Frame prep.

#1

Post by sem520 » Wed Jun 10, 2009 9:59 pm

I just picked up a pre-52 panhead frame; it has no stamping on the right top motor mount, and it has squared horn mounts welded to flattened tube (which leads me to think its a late 49). It has been modified by filling in at the neck as if it were raked. I took it to a local body shop and the guy said I could use a heat gun to remove the filler (it's shinny like lead when scratched and I see no welds). Is this method of removal safe? What is the most effective way to go about this? I want to be sure it has not been repaired or otherwise altered, and I would like to have the original look on it. Ive attached a few pictures. Thanks for the help.

Even a Bernzomatic and a wire brush won't put enough heat on it to affect temper.

Ifn it did, it would probably only stress-relieve!

'Tother end of that is a frame is a big heat sink,might need mapp gas.Regular body solder was mostly 70\30 lead-tin,takes more heat than lead.PLEASE wear a face shield and gloves and work outside!

Thanks, it has been welded underneath the fillers I'm going to try to cut just inside the welds to see if it has been altered or if they just welded for cosmetic reasons.

Thanks Again
