This fiddle had an old set of Roth machine pegs installed. It was reamed out almost to the hilt of my reamer, around 9mm. The holes were also somewhat crooked. After glue sizing and scoring the bushings/holes, I let it set over night. I'll start carving them out and flushing them to the surface tomorrow.
I need to buy a spiral reamer. I got the chance to try one out the other day and it had a far more stable feel than my straight cut one. I think the flat edge of the blade against the straight grain of the new bushings tends to catch and chip. On the other hand the curved blade on the spiral reamer cuts at a slight angle avoiding this chatter. That's the theory anyway.
