Richlite & primary bracing

Post by jamtor » Tue Jan 12, 2021 7:08 am

Hi, and happy new year! I have 2 questions

1. Has anybody tried Richlite for a bridge material ? Felt very light and should be strong enough, i guess.

2. Before i rabbet the part of the primary braces that goes over the bridgeplate, is there suppose to be space between the underside of the primary braces and the bridge plate or should it be air tight? i'm guessing airtight, but the book doesnt metnion this and it was unclear on the photos. just want to make sure.

thanks!

I would not use Richlite as for anything on a guitar. It is a paper product. I have played with rocklite https://www.rocklite.co.uk/ which is compose of wood fibers made to have wood properties.

Based on the question for the bridge plate, I am assuming a classical where the center fan braces cross the plate. Those should be tight enough to get a good glue joint between the brace and the plate.

I've never tried Richlite or Rocklite, so no view from me on that.

Regarding the rebates, classical or steel string, they should be tight. Don't forget the thickness of the carbon cloth in the SS situation. One way of getting the rebates to fit well is to leave the braces a little tall, cut the rebates a little deep, but evenly. (The rebates can also be cut with a router). Then plane down the bottom of the braces until the rebate fits well. You need to get good contact of the bottom of the braces on both the sound board and the bridge plate.
