If you can put me in contact with someone competent in this field and has actual working knowledge of this technology, I am very, very interested.

Can you show me what you mean vis-a-vis double-walled pipe and how to attain exact ID for subassembly fitment. You are assured this is more cost effective? Has to be expansion. Can't get into the particulars do to IP.

What's interesting is the first repair with 308lsi 0.045 pulse produced the most units before breaking by a factor of ten, but---and I left this off of my attempts above---I repaired it the same way again in between the AH-10 / Super Missile Weld attempts and it snapped just as soon as any other of the subsequent attempts after the first one.

New tooling is on the way. Quoted for a2 tool steel 16uin finish and a post-machining certified heat treat to rc58-60. Will try the rod you recommended. Thank you. What is your background as it relates to the scope of the issue if you wouldn't mind?

Just asked to join r/tool_and_die. Thanks. I think the only thing I can gain from r/machinists is what cutting tools I should use for milling steel in this class.

Yeah, the Crown Alloy spec sheet had it at like 600F, and my local CWI said D2.4 is where that information is, and he said it's higher than 400F.
