21-23 series rubber sill plates.
Posted by HH56 On 2014/11/6 11:43:42
Made my first attempt at repro'ing sill plates out of urethane rubber. The test piece turned out better than I expected but based on how it looks in the door opening I believe there is a problem I didn't catch -- or need to compensate for.
All of the 47 and 48 originals I had to work with are in poor condition but all seem to be finished the same on one edge and that edge is the question or problem. Question is should there be a tapered rubber edge on the side facing outward next to the Packard name to match the other 3 sides? None of the original pieces have one so either it was not there originally or being thin, it has broken off on all of the moldings I have. Here is a photo of the repaired 48 pieces in the form ready for a mold to be cast and a photo of the test piece I made.
Before someone says it, yes I know the Packard name is slightly different between series but the 47 pieces I had are missing large chunks and just too far gone to use as a mold. Maybe there is more of a difference than I though so can anyone say if the width is also different between series.
Does anyone have decent enough originals or repros that they could post a photo of one of the moldings mounted in the door that shows all the edges. Also, how hard should the rubber be. The test piece I made is shore 40A which is firm to the touch but still relatively soft to bend. I'm thinking they were probably harder so any info there would be appreciated.
