Uke bridge

Post by vandenboom » Sat Aug 26, 2017 11:48 am

The uke bridge in the pic is (Cooktown?) ironwood that I received with a uke kit a few years ago and I retain to copy.
The scalloped ends appeared to have been done with machinery but I don't think I can do that on ironwood with a router. So I always do the ends by hand (chisels, scraper, sanding) but am not always 100% satisfied with the end result.
The radius of that scallop is about 3/16".
Just wondering what to do differently to get a result that matches the original.

Thanks. Frank.

Ok that's great Frank...I could bring up the image on my viewer but the forum software didn't like the file.

Suggestions to get that nice tight radius curve in your bridge wings. I'd drill a 3/6" hole through the bridge blank using a forstener bit before cutting out the meat from the wings and then tidying up with files and sandpaper. It's a method commonly used to make pyramid bridges.

Another option is to file the channel with a small diameter rat tail wood file.
