Hello
Was watching American Chopper this evening , I see things on that
show that make me cringe but I do enjoy the antics of that family,
they always refer to Pipe if they are building a frame out of Tubing
etc. , this evening they were working on a dragster bike for NAPA and
when it came time to paint the machine they said that powder coat
couldn't be used because of the heat involved would ruin the 4130
tubing , seems like a lot of engine mounts and other A/C parts will
have to be junked , would like to hear some thoughts on this concept
, as an A/C welder it is of interest to me.
Thanks

Powder coating won't hurt 4130, but is NOT RECOMMENDED for aircraft
Responding to an "old" thread here, but powdercoat cures at about 400
deg. F.

Still not enough to change 4130



Powder coating is done at what, 275 degree F? I gotten my airframe
hotter than that by cussing at it when members wouldn't meet up
properly. 4130 will see it as a pleasantly warm temperature, suitable
for shorts and maybe a light sweater.
