Couldn't find the ""made a mess of that" thread to post this, so starting a new one.
So, cutting binding ledges went not too bad in the beginning with my tower jig and SM bits set, but purling ledges on the back required that little spacer between the bearing and the cutter, NOT under the bearing as I had placed it, so.....
Back plate suffered a little bit of router rash, which was successfully removed by using using fractionally wider and deeper binding ledge for (2mm) bindings and routing for double purfling strips, and the top's ledges matched to that width.
After fitting double purflings top and back, I lost an inch of the top's purfling somewhere - broke off during some scraping, so...
Routed off the top purflings that remained and thought, well the back purflings could be better fitting, and went to rout them off as well...
The deeper binding ledge I'd routed now meant the bearing was dangerously close to riding up into the ledge on the back because of it's very tight cylindrical radius, fortunately not much damage was done, but my sphincter was getting a LOT of exercise, and by removing the jig's counterbalance weight to keep the router from tending to lift, i was able to do both the runs needed, but never, EVER, want to go though that again.
Oh, and I roasted the beautiful flamed maple bindings dark brown with the heat blanket when bending them, just for good measure......
NOT my best day
Cheers
