My two current snare builds had kind of stalled. Foundering on my inability to cut a neat/smooth inner bearing edge…
I finally got around to addressing this issue. And the results, whilst far from perfect, are both tolerable and encouraging.
Snare #1, above, is probably coming along better, in this respect. Both require a lot more fiddling and fettling. But snare #2 needs much more.
The shell wall thickness and the smoothness of the inner bearing-edge bevel, on snare #2, are much more varied. I’m thinking about what kind of jigs or tools I might make to help sort this out.
Snare #2 also needs the outer bearing-edge enlarging a bit, so the two bevels meet in a ‘sharp’ edge…
The reason I was finally able to get these inner bearing-edges cut, is that I was able to mount my new Katsu palm-router in the jig originally made for my older Titan plunge-router. As pictured below:
Experimenting with a bearing and various stops, I finally came up with a method that appears to work. Albeit, as already noted, far from perfectly.
