Ooh baby.. took delivery of my Miller Bobcat 250 today.. spent a few hours trying to work out how to lay out the truck.. I want it to be aesthetically pleasing as well as functional.
Here’s the current layout.. Click to enlarge
Large compressor between the two tool boxes, air reel and oxy/acetylene reel either side between the welder and the boxes.. there’s room for the smaller gas bottles between the toolboxes and welders and I’m tempted to run with just the D size bottles (about 650mm high).. More trips to BOC for gas, but safer and so much easier to handle.
The look of the gear on the back of the truck really floats my boat. It fits right in.. pleasingly the Bobcat the the Toolboxes are almost exactly the same height..
There’s still stacks of room for more boxes if necessary and good room at the back for a work surface..
There’s room underdeck for ladders.. and along the chassis rails on the sides for more saddle style boxes and storage..
I’m liking it.. but soon I have to make it earn me money as well.
I’m going to need to hold about 5-6 “E” size cylinders of gas on my truck in the near future.. Argon, Acetylene, Oxygen, 2 x Argon/CO2.. being a cautious kinda guy the idea of carrying 6 cylinders of gas around.. 2 of which are potentially capable of becoming fireballs :).. I thought I should google some ideas for a bracketing arrangement to allow the cylinders to be retained snugly and changed over easily.. so I image-googled “cylinder holder welding truck“..
And one of the first results was the aftermath of an Oxygen Cylinder explosion on the back of a ute.. scary stuff!

Lots of images and detailed information on how it happened at the link..
If you need casters in Adelaide the FIRST stop you need to make is the Industrial Truck and Equipment Company.. awesome range.
With my Silver J3 Bedford in the shed I’m having to squeeze work on other projects around it.. I can sort of shove it over one side of the shed by jacking the differential up on a rolling floor jack then rolling it.. it slips off lots, and is a bit dangerous..
In the shops I’ve seen “dollies”.. a sort of low set trolley for the wheels to sit on so you can move a car around a shed.. but I’ve not seen any that would fit my truck tyres, especially the dual rear wheels on the J3.. additionally I’ve seen reports of the casters on the store bought dollies snapping off.. which is rather surprising for a cheap product made in China and sold at budget car parts shops!..
I’ve been wanting to make my own.. today I made the first two of four that I need.. Check it!
The casters are rated at 250kg each.. the kerb weight of the truck is around 2.5 tonnes.. spread over 4 wheels.. each of the dollies I made has four casters.. or 156kg per caster. With the 383 Engine the weight is probably up a bit at the front.. well within the rated load of the caster.. in any event.. a failure wouldn’t be catastrophic.. the truck would drop a few inches on one side.. when its being worked on I plan to jack it up a tad and pop the jack stands under it for safety.
Excluding travelling time to pick up the casters the total build time was only 2.5 hrs.
Holy crap.. it seems Women can do NO WRONG at all.. even when they strap on explosives and blow themselves the fuck up in a crowded market or something its because they are VICTIMS!!
When Men blow themselves up they get the disrespect and condemnation they so rightfully deserve, there’s no attempt to justify or explain their actions.. they are just written off as “Radical Islamic Terrorists”, there’s no examination of the long path of discontent or indoctrination they’ve been subjected to.. no attempt to gloss over their actions.. But that article attempts to smear a righteous veneer of respectability over the actions of Female Suicide Bombers in Iraq.
What a crock of shit that article is.
I made a little Bench sorta seat for near the pool today.. 4 hours work.. if I exclude the 45 min drive to get exactly the right fastener from the specialty fastener store (cup headed, stainless steel, machine thread, recessed drive).. and the 30mins it took to select the timber (Jarrah) from the Timber Store..
The fasteners holding the timber down are set into threaded holes in the metal frame.
The Jarrah is oiled with Linseed Oil.
The frame is made from 40mm x 40mm steel with a 4mm wall, it weighs a tonne and the legs didnt need any additional bracing thanks to the wall thickness.
I’m very pleased with the result. There’s something particularly satisfying about blending hardwoods and steel.

Apparently Aussie Blokes are going soft..
I can only concur, we’re on a slow spiral into a population with amorphous sexuality.. the biggest problem is the increasingly ostentatious houses that, wives, mostly want.. 4 Bedrooms, 2.5 Bathrooms, Gourmet Kitchen, Columns, Grand Entrance.. but with JUST enough room in the garage to park the two cars.. and outside, a pergola and huge BBQ.. but no more than a tiny garden shed.. what an impediment to a guy knocking up a piece of furniture, restoring a car, or fixing the toaster.
In any event, so many wives eschew furniture that doesn’t grace a new glossy catalogue, would never be seen dead in anything but a boastful new black SUV (and certainly would never suffer the social ignominy of oil drops on their front driveway), and view the broken toaster as an opportunity to upgrade to the latest model.
Indeed, any activity that detracts from a wives centre-stage, Oscar Award Winning, portrayal of their personal Urban Empowerment Success Story must be crushed with that subtle emotional manipulation that so many Wives are so darn good at. ZANU-PF could learn a few lessons from them on maintaining their absolute power.
But Wives are not solely to blame in this descent into a common sexuality, they are after all just being led by the nose (like prize winning milch cows) by exceptionally effective marketing that’s performed by a bevy of corporations desperate to maintain the growth in their profits. Guys who “can do” are an anathema to corporations who would prefer that we are all compliant and eager consumers… ready to toss out that Toaster, upgrade to a larger house, buy a new car rather than fastidiously maintaining the older one, and spend $999 on a particle board bookcase with a glossy finish rather than $102.50 on solid timber to build our own.
A good read on male suicide in Australia.. If Men were Whales..
As Lou has correctly identified previously.. one of the great challenges in so many professions is estimating how long a job is going to take. Software, my previous career is probably the worst-case scenario.. a broad estimate of “two years work for 3 guys” can so suddenly become “4 years for 6 guys”..
Hopefully that kind of blowout will be a long distant memory.. although it has to be said that software schedules are so often decided on the basis of “political correctness”.. a Manager who has a fixed idea of the time-scale (often influenced by their market) who hires a contractor or contractors and then vociferously express their view on the schedule.. it’d be a brave Contractor and a rare good Guy who, in the face of a kids and a mortgage, has the guts to bluntly estimate a realistic schedule and present it for approval.. After all, 2 years of good income and a late project is so much nicer than 3 months of income and a “we won’t be renewing your contract beyond the initial 3 months talk” from the Employer. And its not just Contractors that suffer the temptation of underestimating software projects.. Traditional Employees are so often pressured, without intent, to massively underestimate software projects.
Anyhow.. back to the future.. I’ve started a few projects at the USW, light fabrication of various bits and pieces, some pergola furniture, some play equipment, the tray for the silver truck and I’m fastidiously noting the number of components, the number of cuts, the number of welds etc.. I’m hoping it’ll give me a very slight headstart when I get serious about Dunc 3.0 “Mobile Welder” later this year.
Thankfully, a small on-site welding job, or off-site fabrication only has the potential to un-balance me for a week, maybe 2-3 at the most. I’m sure the first few months of Dunc 3.0 will be wild ride as far as estimation goes but even significantly underestimated jobs will deliver huge paybacks in experience, confidence and contacts.
Bye Bye 2-3 year schedules. Hello 1-2 weeks schedules!
Finally got the first of the seats for the Silver J3 Bedford back from the Trimmer today! Red Leather, the whole base sanded, primed and painted black first. Passenger bench seat and back, headliner and carpet to follow shortly (but his nickname, proudly proclaimed on his number plate IS Slacker, so I’m not holding my breath!).. No great hurry, still waiting on tailshaft and it needs a tray before its road legal as well. Happy to wait I guess, the Trimmer’s a decent sort who’s had a rough trot of late (White Tail Spider Bite, cellulitis and a bad flu)..

Too good for a Welding Rig.. the Blue Truck is getting converted to the workhorse and the Silver Streak will be the occasional driver.
I sat in the new seat after he left. I made some V8roooooom!!! V8roooooom!!! noises and decided I like the ergonomics of the shifter. It’ll be a comfortable truck.
Floor carpet will be black and a decision yet to be made on the headliner.
Sharan Burrow, President of the Australian Council of Trade Unions is worried that changes to the Workers Compensation Scheme in South Australia will unfairly impact women.. WTF?? 99% of Workplace Deaths happen to men, one can only assume that they MUST feature massively higher in workplace injuries than women..
Bit the bullet today and ordered a big engine driven welder. A Miller Bobcat 250.

The photo gives no idea of size.. its about 3/4 the size of a fridge lying on its side.
Its a seriously grunty welder, petrol engine and it includes its own generator. Multi process.. stand alone it’ll do stick at 250Amps (100% duty cycle!).. with the addition of a wire feeder and an HF kit (also ordered) it’ll do TIG and MIG.
I’m going to need an Aircompressor on the back of the truck (running off the generator) to drive my Plasma Cutter and various air tools.. a little fridge to keep some Coke Zero cold would rock as well
The wirefeeder is a neat unit, shaped like a suitcase (complete with a carry handle on top) it introduces a level of portability once on site (with a long cable).

The price is less than I was anticipating.. The base welder is around $6K (ex gst).. the Wirefeeder around $2400 and the HF kit (for TIG work) around $2000. Throw in a few cables, TIG torch, MIG gun and the final price will be somewhere around $12K.. delivery anticipated for next Wednesday.
A few Toolboxes, some new angle grinders, another bench grinder for the truck, some big extension leads.. I should be set up for well under $20K.
Most of the News Services I watched on TV last night (I flick around a few) featured the story of a man who regrew a severed finger after a model plane accident.. I was skeptical, at least one of the news services had an animation of a finger regrowing from the middle knuckle..
It was a neatly pre-masticated story, ripe for consumption by lazy news consumers.
A scan of the blogosphere shows a similar skeptical sentiment and a little more information.. Bad Science has a good report on it.
A scan of the traditional news services on the net show that the story has been swallowed pretty much hook, line and sinker by them.
More and more I’m loving the analysis of “news” that takes place in the blogosphere, its a neat antidote to the laziness of the traditional media that will grab any story that will fill a few minutes and titillate their audience. I pity the folk who have nothing but the TV or the Newspapers to keep them informed, they are doomed to move through life in the haze of misinformation, half truths and lies that are peddled every day.
I’ve finally gotten back onto the Bedford J3 that I’m building (the silver one/383 chev one).. I got a bit side-tracked by the installation of the Swimming Pool.. It feels good to be back on it. I finished off the installation of the B&M Shifter today, the safety interlock for the starter motor got wired in and the cover and boot over the shifter got installed.
I trial fitted the radiator I bought for it.. its a J Series Bedford radiator but its off the bigger version of the trucks (J4/5/6). Same design, but deeper. The bottom hose is going to be a tight fit as the front cross member which can be mounted in two positions is mounted forward.. the bigger trucks have it mounted in the rear position. The bottom radiator hose, without work, will foul.. I need to craft up a 90deg upward bend as soon as the hose exits the radiator in order to clear the cross member.
The top radiator hose, rather pleasingly, has a very similar profile to a hose that would have fitted to the original 214 engine. No great challenge there.
Gauges are next on the list, oil pressure and temp. I’m not running with the Bedford gauges. I have some matched gauge/senders and will mount them on the dash to the left of the original instrument cluster.
The Trimmer has promised me my new leather covered seats for the J3 this weekend.. I’m not holding my breath, his nickname isn’t “Slacker” for nothing I’ve come to find out.
I replaced the Radiator in my little red J1 this afternoon.. Top Radiator hoses for the Bedford 214 Engine/J1 application are no longer available.. a more than adequate replacement is the top radiator hose off a BJ45 (early 1980’s) Diesel Landcruiser. It needs to be cut down a couple of inches on the thermostat end but otherwise is a good fit. Part Number CH1603.. readily available.
My son dragged me along to the Anzac Day Dawn Service at 6am this morning. He was keen to but I only went grudgingly.. I rather enjoyed the whole thing though.
A few observations..:
The Scouting movement was out in force, which is great.. How disappointing though that they looked so scruffy and ill dressed.. Sneakers, jeans, shorts, socks, no socks, a real rag-tag bunch.. Which was in stark comparison to ALL of the other organisations present which had a youth component including Army Cadets, Navy Cadets, Air Force Cadets, Police Rangers, St Johns Ambulance, and Country Fire Service, all of those organisations had their youth turned out in matching uniforms..
The attendance was huge.
I detest seeing people wrap the Australian Flag around themselves, cloak-style. There was 3-4 Flag-Cloak bedecked people there.. I hate it not because I think it disrespects the flag but because I detest seeing grand displays of fervent Nationalism and its normally racist rednecks that do it. More though, it misses the point of ANZAC Day.
Every two-bit politician felt the need to be there or send a representative.. Keeping up appearances. Local Government particularly pisses me off.. the Deputy Mayor attended and had to be duly welcomed by the Master of Ceremonies.. who fucking cares? Councils are overrun with lame wankers who have nothing better to do. Abolish Local Government already!
“Last Post” played on a bugle sounds simple awesome.
I just finished a two day stick welding course.. it was significantly more challenging than the MIG course. Stick Welding is a real test of hand eye coordination. Its so much more “coalface” than MIG welding, you’re so much more in touch with the heat, smell and feel of the weld.
I was using a Miller Syncrowave 250DX. This machine allows you to switch between the stick or the workpiece being positive or negative.. or even to put the unit into AC mode so the stick and workpiece alternate polarity. This is new to me, I have a little DIY stick machine that just has an Amps setting. It was an eye opening experience watching the difference between the three modes.
It has a twirly gauge for Amps which is cinch to set compared to most home units which have a mechanical knob to laboriously move the secondary coil within the machine.. the 250DX takes just seconds to dial up an exact Amps setting.
Stick welding leaves slag to be chipped away.. its like Christmas Time when you chip slag away from a weld you take a sausagey looking bead that’s all blacked up and you chip off the slag to expose a shiny bead of virginal metal.
The horizontal welding exercise was really challenging, I tried about 12 different settings before admitting defeat and asking the Instructor for help.. it took even him, a welder with 30 years experience 4-6 beads to get it right.. it made feel a little better.
I spent the afternoon with 5mm plate practising grinding bevels and doing full thickness butt welds.. one root pass, a pass on the back and a second pass on the front to cover the root pass. I went through about 120 welding rods over the past 2 days. I can lay down really neat beads on butt welds on flat surfaces and I can create really neat fillets.. I need a LOT more practise on vertical surfaces. But that comes in levels 2 and 3.
In any event, that most important outcome was recognising a good weld, I can practise at home (even if only on a little buzz-box) and know if I’m producing a good weld or not. I know what to look for now.
I had a brief chat to the Instructor this afternoon.. which went along the lines of “So you’ve been watching me weld for four days.. am I barking up the wrong tree or can I cut it in this game?”.. the response was positive, without hesitation. Which makes me feel a little more confident spending the $30K I suspect it’ll take to deck one of my trucks out with the gear I need.
A young Japanese girl had been taught all her life that when she married she was to please her husband and never upset him.
So, the first morning of her honeymoon the young Japanese bride crawled out of bed after making love, stooped down to pick up her husband’s clothes and accidentally let out a big fart.
She looked up and said:
“Aww so sowwy…excuse prease, front hole so happy back hole laugh out loud.”
I got a new favorite song these days.. Its Bruce Springsteen singing “Racing in the Street..”
The lyrics in part say:
“I got a sixty-nine Chevy with a 396
Fuelie heads and a Hurst on the floor
She’s waiting tonight down in the parking lot
Outside the Seven-Eleven store
Me and my partner Sonny built her straight out of scratch”
And later it says:
Some guys they just give up living
And start dying little by little, piece by piece,
Some guys come home from work and wash up,
And go racin’ in the street.
How awesome these lyrics are.. they neatly spells out two things… 1) How cool old cars with big engines are and 2) How important it is for men to have an absorbing passion in their lives beyond their work and family.
Far too often these days men come home from work to lives that are devoid of passions beyond their kids and spouse.
I finished the very first component of my MIG Welding Course today.. I had a ball
It seems I was the only attendee to get right through to the last weld-exercise. No great achievement perhaps, there was just four of us. Here’s a sample weld, a “fillet” which is used to join two peices of metal at right angles to each other. It was welded on the horizontal. Its not perfect, not even close, but much better than any fillet I’ve ever welded before with a MIG Welder.
Click to enlarge:
I’m really impressed with the quality of the instructors welds, they did some demos and those guys.. they’re awesome. They are Metal Gods. I want to be a Metal God one day.
I mastered vertical down welds today for the first time.. welding on vertical surfaces is really difficult, the molten metal wants to fall off thanks to Mr Gravity.. Vertical Down is difficult.. Vertical Up gives a much stronger weld but takes a LOT more practise.. I tried some Vertical Up in the last 20mins of today and can’t wait to have another crack at it.
The next 2 days is all Stick Welding, I know this is going to be more challenging, the physical action of dragging a rod along a flat surface at a precise distance above it at the same time as the rod is growing steadily shorter is pretty much double the challenge for Hand-Eye Coordination that MIG offers.
Sorry for the steady stream of welding related posts.. its all thats in my head in this week.
Spent all day at the Welding Course today.. I thoroughly enjoyed it. I’ve learnt that really, really, really good welds take a LOT of skill. What I thought were reasonable beads 2 days ago I now know were really ordinary welds. The Instructors are, thankfully, merciless there’s no sugar being blown up anyones arse about their welds. Their criticism is incessant, incisive and useful. My welds progressed nicely today.
Today was all MIG welding. I think the MIG experience I already have was useful, but I’ve discovered I’ve picked up some bad habits that need to be unlearnt fast. I’m very glad I didn’t turn up completely green as I was discreetly looking at some of the other welds from the green attendees and they were terrible.
I had a long chat to the Instructor about the idea for a mobile welding rig business. He was very upbeat on the idea and gave me a good run down on where the work can be found and the going rates and a few other ideas on niche areas that I could target. The inevitable suggestion that there’s squillions to be made in the Mines up North came up, of course its not an option but the money on offer up there and the opening of new projects the at Adelaides Submarine Corp locally will significantly drain the local talent pool and bring up rates with it.
There was an Oxy Cutting course running at the same time, it had around 10 Apprentices on it, it was amusing watching them during the breaks, they were all around 18-19 and all struggling to find their identity in life, most of them were sporting some kind of gregarious body piercing, it would seem big, big earrings that make very large holes in the ear lobes are the in thing at the moment. They look disgusting. Surprisingly they almost ALL smoked, and they had those exaggerated actions that people who still thing smoking is cool have, the “look at me” way of smoking. Many had exaggerated swaggers, all desperately trying to be part of the group, no one game to adopt their natural personality for fear of being excluded. They religiously took their breaks and stayed out of the workshop for as long as every break would possibly permit.
All in all, after just one day of a lot of courses to follow I’m feeling quite upbeat and positive about carving out a very good living into the future, in my local area, the hours I choose and with the flexibility to take holidays when I want to.. and all with skills that will never be out of date.
I have two dogs.. a Dalmatian Bitch and a young male Staffy Cross..
The Staffy follows my lawn mower around eating large amounts of the grass clippings that it shoots out. Perhaps he should have been a cow.

Rather more disturbingly my female Dalmatian follows the Dog-Cow around eating its poo. Its the most disgusting thing I’ve ever seen I think.
Off to School all next week.. Level 1 TIG, MIG and Stick welding.. 2 days each, but I’m trying to squeeze it into 4 days. Followed later in the year by Level 2/3 TIG, MIG and Stick and 2 days of Oxy Cutting training.. then a 5 day certification course.. a grand total of 37 days training. The cost seems cheap, about $4000 in total.
The training is for two reasons..
One.. I love welding and fabricating shit out of metal and I want to do it better.
Two.. For at least the past 5-6 years I’ve been kicking myself that I didnt make a move into a manual trade earlier, Information Technology as a career sucks big sweaty dog balls. It’s SOMETIMES fun but its most often pure drudge, and your skills depreciate so quickly and its output is so ethereal to so much of the population. So, for the THIRD time in my life I’m reinventing what work I do.. I’m somewhat in a hiatus period at this point in time, having sold a stack of assets I don’t really need to do much, for a few years if necessary.. but I still want to earn money, and have a stack of fun at the same time. I have ZIP interest in doing this in the form of a regular job, I will never submit myself to wage-slavery again..
So during the training, over the next 6 months or so I’m going to set up one of my trucks as a complete mobile welding platform, a big engine powered multi-purpose welder (TIG, Stick, MIG, Generator, Compressor) and I’m going to build a shed on my property that gives me the room to do light fabrication (gates, custom trailers, custom truck bodies etc). The combination of the “at home” light fabrication and the mobile welding business, I’m hoping, should deliver me about $2k-4K of income a week, enough to keep things ticking over without eating equity. Most importantly, I’m investing time and money into skills that are extremely unlikely to depreciate, they’ll be with me for life. Perhaps when I’m too frail to do the work I can teach other people to do it.
I’m REALLY looking forward to immersing myself in a new skill and being able to provide specialist welding services to a variety of industries. I love building sites, I love factories and I love exercising a skill in a public manner that results in products and output that a large percentage of the population can really appreciate.. I love hearing comments like “Holy Fuck.. you MADE that!!???“.. its a reaction you almost NEVER get in IT.. the more common reaction is “What the fuck?? When I press this button I get this.. I was more expecting this!! You suck!!”.. The huge foundation that you build for software is hidden, its like an Iceberg.. but the visible portion that your users react to is the 10% of negative crap that floats on the surface. A bit like a turd in some ways. Your kids, your spouse, your friends just don’t appreciate what you do in IT. And there’s almost NOTHING more rewarding than cracking a beer and sitting back and gloating over something physical you’ve made. Being exposed to the Building Industry will deliver me opportunities and contacts that I can leverage later when I get back into property.
I had to go and buy a few long sleeve work shirts today, I’ll have to wash them a few times, and wipe them on the spring shackles on one of the trucks with them and leave them in the sun for the weekend in order that I don’t turn up with shirts that look neatly pressed, and free of stains, grease and evidence of actual work. In any event, I feel a level of anticipation, excitement and challenge that I haven’t felt for a very, very long time.
I’m going to practice my stick welding this weekend, since I purchased a new MIG welder last year I’ve put my little stick unit aside, but the basis of all construction welding is stick based and I want to be confident on day one so tomorrow I’ll break out my stick unit, pop my rods in my Rod Oven for a while and run some practice welds on a variety of stock for a couple of hours.
I’ll post a few photos and comments from next week.. I’m unsure what to expect, but if there’s anything that the last 21 years of working have taught me I generally succeed at whatever I choose.. most importantly I’ve almost always taken on tasks that I’ve thought utterly beyond my skills and I’ve generally managed them to a successful completion.. There’s been a couple of significant failures (I’m deeply sorry, you know who you are) but I’ve taken more out of those failures than they’ve taken out of me.
Duncan 3.0, more to follow.
Has anyone else noticed how younger women fondle their mobile phones.. they lovingly grip them, sliding their hands up and down the phones, always clutching them close to their body. There’s something particularly phallic about how women handle their mobiles.
Went shopping today.. the usual interminable queues at the checkouts.. The usual frustration at the unfairness that the typical queuing system presents, you have to choose a checkout, making an assessment of the number of people in that queue, how many items they have, the apparent professionalism of the operator etc.. Then, there’s a price check that has to be done, new checkouts get opened, but your buried so deep in a queue that you cant avail yourself of it.. the people BEHIND you can and they get through faster..
Target thankfully have seen the light in Adelaide and present just ONE queue, the head of the queue goes to the first available checkout. I like that. It removes all of the guesswork and frustration. I wish more stores would adopt that approach. It makes so much sense.
As far as the internet has come in connecting people together its done nothing, at least in Australia, to connect people living in close proximity to each other. Nothings popped up that has successfully facilitated communications between residents in a street, a block, or a suburb..
I’ve never liked Football.. least of all Australian Rules. Its a thuggish sport long overrun by violent, self obsessed wankers. And, for whatever reason, its above the law. On field incidents are apparently beyond the reach of the laws that govern the behaviour of the mere mortals who don’t play the sport.
Players are free to attack each other with as much brutality as they choose and be immune from any punishment above and beyond the penalty dealt out by the governing body of the sport (simply being excluded from a number of future games). Blatant on-field violence should result in formal assault charges and prosecution.
The on field violence is the least of the ills of Australian Rules, the players are uncouth, rude, drug ridden, overrun by alcohol abuse and provide no fitting role models for the battalions of kids that cheer them on every weekend.
And WHY do so many of them feel the need to spit on the ground with such self-aggrandising showmanship during the game? Its disgusting.
Well.. it seems prostate screening isn’t effective in reducing deaths from prostate cancer. Back to square one.
