The classic group has visited Richard’s garage twice to see his progress on his lovely 912 project. Currently he’s is finishing the carpet install. Which starts with the installation of the sound deadening.
Thanks Richard for taking the time to share!
Sounds deadening: The original tar based sound deadening was replaced with 3m rubber pads cut to fit and pressed in place with a roller, these pad are less than half the thickness of the original but are very dense and less than 2mm thick which saves on weight. On the areas exposed to engine heat I used a dynamat style sound deadener with foil, this cuts and rolls out exactly as the 3m pads and is the same thickness.
I decided to build my own carpet set using the correct German Charcoal square weave sourced from World Upholstery, the carpet is noticeably thinner that the original but overall very well made and cuts easily to size using the old carpet set as a pattern. Total cost of the material was about $600 vs $1400 for a finished set. One word of advice is to order the several yards (4-5 yards enough to do the entire set) as the dye lots can be different from roll to roll. I found out the hard way as one roll came almost black and I ended up not using this
batch and ordered another yard from a different vendor.
In order to sew the vinyl binder to the carpet a good quality sewing machine is necessary, I decided to pick up a Juki (Japanese) walking foot machine that can easily sew through several layers of leather without a hitch. There are several good walking foot machines from several countries, PFAFF, Consew, Singer, but the Juki stood out as among the best. I was surprised to see that the Porsche factory uses the Juki over their own domestic brands. https://www.youtube.com/watch?v=isiyRH0JDpI
The issue with sewing the binder to the carpet is mostly around doing inside curves which do not allow for an attachment to be used. My reason for doing the carpets myself is that the local upholstery shop refused to help me with the carpets because of all the curves. I started out using a binder attachment which worked very well on the straight edges but needed to be removed before going around curves. After trying several times I just decided to ditch the attachments completely and sew the binder on freehand which matched the original carpets where you can clearly see the binders were done the same way. It took about 1.5 days to sew up the complete set, I messed up on a couple of edges but mistakes can be cut off with a razor blade and you just start over. I was please with the outcome and got some good experience sewing that I can use in the future.




Beautiful work Richard!
This is true Craftsmanship!! Very nice job on the carpets and everything else.
