    I have a surplus flame spray set up and have not a clue how to use it. Has anyone ever done this? Any pointers?

    Unchartered waters here. :)

    "Flame Spray"?

    I have no idea what that is, but it sounds like too much fun to be legal. :gig:

    Flame spraying is a process to apply a rather heavy plastic coating (tyically nylon) to metal parts. I guess it's like powder coating in a way, except there's a torch in the spray head that melts the plastic particles as they pass through the gun, then they harden as they hit the cool part being coated.

    At least that's how I understand it. I've had it done, but never seen it done.

    Flame spraying is also used to coat steel with aluminum for rust proofing the steel and so it can be directly bolted to aluminum parts

    It still sounds like too much fun to be legal. I want one. :)

    Thanks for the explanation of what flame-spraying is. Before you cleared it up, I had visions of singed hairs on one's posterior. :gig:

    It's a tool that is used to apply sintered (powdered)metals to a variety of materials. Including applying aluminum to composites. Boeing used it to give lightening strike protection to composite panels of airliners by applying sintered aluminum. Carbide coatings for wear resistance etc.. It uses Oxy Acetylene and compressed air I think. These sprayers are incredibly exspensive and require some knowhow of which I am lacking. BMW uses a process like this to make their motorcycle cylinder sleeves go 200,000 miles with no measurable wear by applying sintered carbide. They are used to repair worn shafts. I have heard of some body shops that spray steel into rusted areas of car bodys as a repair. Boeing also used it to apply carbide to the rub plates of the 707 elevator counterweights of depleted uranium. This is a tool capable of amazing things and I sure would like to know how to use it. If for nothing else coating my exhaust system. Just thought maybe someone here has had some experience with them.

    Any numbers or placards on the equipment- shouldn't be too hard to google the manufacturer and then get some training.

    I used a flamespray unit back in my Navy days. Post some pics, and I may be able to tell if yours is complete. Then I may be able to give you some pointers.

    I played with my set-up 10 or 15 years ago--Takes a LOT of Acetylene & Oxygen & some compressed air. I think the air was just used to run a turbine geared down real slow to feed the wire you
    used for spraying..

    Seems like it sticks best to a fresh sandblasted surface---I tried brass.
    and aluminum. Jerry

    Now thats one heck of a contraption! I like how you had one simply lying around.

    This was the first google result that popped up:

    http://www.twi.co.uk/content/ksrdh001.html

    Seems quite informative. Reading it... once again... what a contraption!

    I did a search for metco and spray and found this site
    Sulzer Metco - Products and Services

    A quick look at the thermal spray section on the left shows some guns that are similar to what your picture looks like. If you check under the "contact us" heading for Americas, service & support, you find a list of what appears to be dealers for the equipment. If nothing else, maybe you can find someone reasonably close to you who can point you in the right direction.

    Good luck, keep us posted. I dunno what I'd every use the process for except maybe a replacement for powder coating or paint on steel parts, but I'd sure like to see it in action!
