Inserts wrap-up
Last night I finished up the inserts, by boring the through holes to the proper diameter. Since I had 3 blanks, I chose 1-1/2″, 2-1/4″, & 3″. After a few days of needing a jig to do everything, it was really nice to just throw the work piece in the 3 jaw, and start boring. It took about an hour to bore out the inserts, and chamfer all the edges. It was pleasurable, as nothing had to be precise.

Three inserts ready for use.
This afternoon, I installed and leveled the 1-1/2″ insert, as it’s the one that I will probably use 95% of the time. and then as a test I cut a short sliding dovetail. It’s shoulder was perfect aside from some tear out. The plastic insert produced a wavy shoulder, because it would flex as the board passed over it.
