It happens, I dropped the bridge for Stu Fuchs ukulele on the concrete floor of the shop. I was fitting the saddle. Of course it broke. Not a huge deal, but a small set back, Then I thought, This might be the chance to do a better job of installing the new "string surrounds" Here is what happened.
The problem and the solution
Here was the set-up. A new bridge with holes mimicing previous uke measurements. Then scored with an awl to guide the drill. Holes drilled to guide the larger bit that would seat the acrylic "donuts".
Here I am drilling the small holes to accept the "donuts"
now those hole are drilled. The depth of the holes is measured so as to seat as much of the "donut" as possible.
Now the "donuts" are put into place and CA glue is applied with this device.
So here is the solution. Sanded, the beginning of refinishing, and the string exit holes tapered with the little device shown on the right. The bridge, after French polishing will be attached to Stu Fuch's instrument and the hole will be tapered even more to provide a smooth bend to the saddle.
