The PHILCO Phorum

Hi everyone, Recently I read a post here on the Philco Phorum which pointed readers to a Youtube thread showing how a chap cast replacement knobs in resin using ,I think , a silicone female mold made from the original knob.The chap was restoring a Philco valve tester. Does anyone know  where I can find  this thread? I ask on behalf of someone here in N.Z. who is keen to follow this up. Thanks.

Hi, this one may be the right one, he uses that technique and has a couple vids showing how to make them - restoreoldradios:knobs
