Here's the DEL-200. I'm still working to dig the Syncro out from behind a ton of "stuff" to get better pictures. S/F....Ken M

WP-26 is aircooled 250 amp torch, no water cooler. It's got the foot pedal and the usual stuff you need to weld aluminum. I haven't used it for anything else, and sadly haven't used it that much. I have a flex head, valved WP-17 25ft I could include in a deal but that'd require a little negotiation....

I'm reducing my equipment at work, so my Syncro 250 and DEL-200 are for sale. Just not using the stuff enough. Syncro 250 comes with WP-26 and I'll include the argon bottle (110CF) if you like. It's down around 500psi, there's enough to test the machine out but that's about it. Asking $1500 The DEL-...

I suspect that in many cases, they're listing the position with nonsense pay so nobody fills it so they can bring in H1x foreigners or other forms of chicanery. Supply and demand, simple as that. We've got guys going without work, yet they're letting in a million+ more people every year. I know here...

Silver solder/braze it? S/F....Ken M

Lincoln Wearshield Mangjet is $191.00 50/LB* ($3.82 LB*) at my friendly local welding supply, but you're buying 50lb cans. You could also try 11018. S/F....Ken M

I just buy 75/25 He/Ar pre-mix. S/F....Ken M

If you use helium mix, you won't need much preheat, just take the chill out with a MAPP torch or similar. That Syncro 250 will be plenty. If it's too hot to touch, it's too hot. Don't let interpass temp get too high either. You don't want to take the heat treat off the block; it's not welding cast i...

Fairly early 1st/2nd generation technique for increasing armour resistance on tanks, mounting the outer steel on springs, over the cast or welded turret. Works up to about 5000fps or so, then penetration is more along the lines of fluid dynamics. Still used for armour intended to resist small arms, ...

If you can spring mount the impact surface, that will help quite a bit. S/F.....Ken M

Not Brodix, but I was involved with welding up a New Century block that chucked a rod using 4943 (not 4043) filler with 75% Helium mix. We milled out the edges square and beveled, then welded in a piece of 6061 to replace the grenaded section, as well as tying into the existing reinforcement weldmen...

330CF bottle 100% Argon cost me $200 bought outright, $50 refills. A 330CF fill of 75/25 He/Ar was $115. S/F....Ken M

It takes about 1000-1100F to anneal brass in a reasonable timeframe.

Pottery kilns are popular for guys making their own jacketed bullet using swaging equipment.

For $200 and not three phase, I'd buy it just to have it, maybe later resale. S/F.....Ken M

Bolt handles are typically silver soldered (brazed) on, but this design won't work for brazing IMO. S/F....Ken M

I work with 25-75t hydraulic cranes on a daily basis and the one thing I can offer is inspect everything that is pre-welded or assembled. As you've indicated, you've had some experience with "professionals" and seem to have a suitably skeptical attitude. I commend that. Good luck. The one ...

This is my LWS. The front side staff can be a little frantic sometimes, but generally not too bad.

Anybody got an online place for Hobart 4953 filler? S/F.....Ken M

weldingsupply.com is another good source for some stuff. They're my LWS, so just pick it up at will-call. And HTP is just down the street too. S/F.....Ken M

They used MIG brazing on some of the newer vehicles with boron and HS steels, trying to avoid brittle HAZ's. For body panels, you should be fine. S/F.....Ken M

Those coils weigh 20k+ in steel, 10K in aluminum. 40+K coils are common. May as well be a solid piece of steel for impact purposes. They destroy stuff all the time. Been a couple cases where foolish truck drivers stop on RR tracks and the train hits the coil. Last one I remember killed 7 people. If ...

Read it again, my friend. I might have made it too subtle for those not in the industry. Coils. 10k-45k+ lbs each http://blog.al.com/spotnews/2009/03/large_Coil%20crashes.jpg Eastern Euro(Russian) trucks drivers are notorious; both for being extremely cheap, and doing all kinds of hinky things.

I've got some strange old Japanese stainless rod that I acquired, I'll check on the exact details when I get home. IIRC it's either 308 or 309, 3/32". I'll be happy to send some sticks off for somebody skilled to play with. If I can recall my thinking when I got it, I planned it for "aw cr...

I've been fabricating trailers to haul coils outta US Steel Gary using my 115V flux core for six months now(those Russian guys always buy everything I can make, but how they complain about the price!) I've started getting checks in the mail from local towing companies. Says it's "commission&quo...

No oiling, no positive control of belt tension, no bucking spikes, all held together by some flimsy sheet metal bracketry.

OK, maybe if you had no other power source in some sort of MacGuyver survival situation, but otherwise?

I picked up something I believe is similar, a Craftsman model from Sears Roebuck, for $35 off Craigslist. Only difference being it's 230v.

It's useful for doing AC TIG off an engine drive. No idea on value, depends on what the market will bear, I suppose. S/F....Ken M
