I am just about ready to take the plunge and order in the materials
necessary to duplicate my current airframe out of 4130. Thanks to all of you
guys for the tips and sources. I have one more question. What other metals
are compatable with 4130 when welding? My problem is in locating any angle
in 4130. So far all I have found is seamless tubing and flat stock. My frame
currently uses some angle 1"x1" angle. I would like to stay with using angle
in these locations if possible. So, now this may sound dumb, but can you
weld mild steel or another alloy to 4130 tubing that I can get in angle? Or
better yet, do you know of a source for 4130 angle?

Has anyone on this list ever welded a thinwall 4130 frame with a MIG
welder?

What is a good source of 4130 seamless and welded seam tubing?

Thanks,
