Hello,
I am trying to resurrect a vintage 1975 Teledyne Titan that has a cracked derailleur dropout. I have fabricated a replacement derailleur dropout from TI 6-4 alloy that is an exact match for the original and "beefed up" in thickness to discourage future cracking. Many thanks to the local vocational school for TI milling the AutoCAD pattern that I created from the OEM blueprints!
I know that after a TI frame is constructed or repaired, the frame has to be annealed or "heat treated" to strengthen the metal and joints. My questions are this:
1.) Does anyone know if Teledyne coated their frames a gray color first and *then* annealed them? (This would save having to heat treat once for the metal and then a second time to cure the paint at a lower temp.) 2.) What temp is required to anneal TI 6-4 metal? I am wondering if the existing coating currently on the frameset will be baked off in the annealing process required to treat the metal... 3.) Is a special paint required to paint over 1975 commercial pure TI metal?
This message has been posted to both the ClassicRendezvous and the FrameBuilders forums.
