I see it sagging but it looks like the center line of the rear tire is about two inches in front of where it should be.

A broken spring shouldn't cause the wheel to shift forward like that. Voting bent control arm as well.

I would be surprised if it was acetylene though. Plumbers mostly use propane/oxy from what I have seen, and use even that less than they used to since it's all gone plastic tubing now, also propane or MAPP is enough for them just brazing 1/2" copper.
Fridgies like me are about the only trade that still use acetylene, due to much larger piping that needs brazing.
Though like a said before, gently caress having oxy/ acetylene inside a van, should use well ventilated utes for stuff like that.

edit: I have heard a case in the UK where a fridgies house caught fire, firies heard there was acetylene on the premises, and just backed away to a safe distance and let the place burn.
The stuff definitely doesn't get much respect to it's dangers down here. Almost every air con company uses vans, and they nearly all have oxy acet in them. Some kind of brazing gear is needed for the job, but a van is more useful to transport a/cs. Strange that nearly every refrig company seems to always have utes. Even though I mainly do a/cs, I still went with the ute, sucks when I need to transport a/cs, but I rather get a trailer for those times, and keep the oxy acet and 4 different refrigerants and nitrogen cylinder, in the tray of the ute, than inside a van.

MAPP is plenty hot for even 2" copper. I just sweated a fitting on an old sanitary sewer line with one. And you're right: that's about the extent of what a plumber would be doing with a torch these days. All they do it glue PVC and crimp PEX. The torch only comes out on repairs, and pretty much only to put a fitting on old copper to get it to PEX or PVC. Copper just costs too much to be worth it.

Well, the other reason why fridgies use oxy acet (and not MAPP), is the heat has to be damned fast and localised. Heaps of seals and gaskets will melt if you try to do fridgy work just with MAPP. Also the longer you heat something, the more carbon deposits inside the pipe which will contaminate the system. So like I said, I can only see fridgies using oxy acet for those reasons, and not plumbers. And every plumber ute I have seen for 10+ years has had propane in it, not acetylene, I'd be suprised if most of them had not switched to MAPP.


VV edit: Sorry, I thought it was a bit off topic enough, without posting a picture that is not a mechanical failure. But yeah, buy that poo poo if you need the quick high temp localised heat of an oxy acet on the road, and not have van go boom.

Had a slight mechanical failure of my own. DID YOU KNOW that if the air supply dies on a plasma cutter, the tip will melt right off?

Air compressor died in the middle of cutting and I didn't realize it. I noticed something was off, so I asked someone to change the air flow from 2.5 to 5.0 (my excuse was I was on a ladder so I couldn't flip the switch and couldn't hear the air compressor over the generator), but that did nothing. After my tip melted, I checked the compressor and the tank was empty because the breaker blew. Joy.

Then the generator died.

And the gas tank blew up.

Which caused a train that was carrying alternating cars of liquid oxygen and LNG to derail.

AND... I'll stop. Plasma cutters melting is pathetic next to exploding train depots.

This is probably a horrible mechanical failure being prevented, but I thought the sheer power involved fit the theme of the thread.

I was leaving the basement of the Georgia Tech Library last night when I heard a noise like a freight train start up. As I left the building, that turned into an incredibly loud roaring/hissing noise from the direction of the Georgia Tech Steam Plant. As I got closer (but still not in full view of the steam plant), the sound reached painful/damaging levels, and I put on my motorcycle helmet to mitigate it. When I reached the steam plant, I saw this:
http://www.youtube.com/watch?v=HKfE9HThrxA

To put things in perspective, the steam plant is right next to the A marker on the map, and the library is in the top left. The pipe venting steam is in the area circled in blue. Bobby Dodd way is a major pedestrian artery to and from the library, and was being pretty heavily used at the time.




The sheer volume indicated to me that the venting is nowhere near normal, and I wondered what sort of overpressure catastrophe was being prevented. I peeked my head into a window of the actual plant expecting to see people running around, but instead I saw one guy, calmly working on something pipe-related. As I got to my motorcycle, I heard a sound like a giant valve turning, and the roar of the steam died down to nothing. I peeked back into the window, and the guy calmly working was nowhere to be found.

I was at a coal plant that did that when they started up. IIRC it was to flush air and liquid water from the tubes and steam drum after service.

It was painful from over 200 m away, even though the plant was pretty low pressure (1800 psi) and the outlet was fitted with a suppressor.

The build the hell out of them period. As a hose monkey, I can tell you they are the hardest drat things to cut apart. Fortunately I've never had the need to do so on an actual accident scene, but the ones we get to cut up in training take some doing. There's no peeling and pushing with hydraulic tools like we do with cars and trucks. This is a Sawzall and air hammer affair all the way, and you have to cut down the bays (under/around the side windows) and open the sides up like mini draw bridges or it just takes too drat long.

Probably a combination of cheapness, the idea that they spend most of the time in 20mph zones (a misconception, but an understandable one), cheapness, lack of specific regulation, and cheapness?

Oh hey remember those dies I said needed to run? Small update. The chromed first stages cleaned up okay with a bit of elbow grease, I got a fella in to sandblast the rest, which made them look much more usable but revealed a shitton of older damage:

[
Much better, though we had to spray a little oil on there as they started rusting immediately

[
A lot of fiddly work, grinding this back to working surface by hand would simply not happen.

[


[
Plenty of old weld repairs visible...

[
Well that doesn't look too bad?

[
Um, will that be a problem? Apparently not for the small volume we'll run.

[
Again, spot the old repairs

[
Apparently this part used to 'run like a bitch' By the looks of it it ran on welding rods.

Anyway, apparently none of this will cause us problems, but it's interesting to see how these things hold up to making a squillion parts.

I've never had the pleasure of welding cast iron (well, once, sorta), but I know you have to heat the poo poo out of it to get anything close to an acceptable weld.

Given how big those bastards are, I can only imagine how much time some poor millwright had to spend with a torch on that. And the water cooled suit you would need to get anywhere close to it.

Cast iron sucks to weld. I've used the Lincoln nickel rods and ferroweld rods on it before. You can do the hot as the sun and keep it that way method or the weld cool and they both work, usually.

Even weird stresses from heat can crack it if you're welding with preheat. Short sections at a time (usually), maintaining even preheat (like 900ish degrees in my experience) and burying it in sand after you're done.


I've only ever tried the preheat version. Cold version and you have to weld in short sections, let it cool, weld again, let it cool etc.
