Thanks for the compliments. The tool rest is adjustable past 90* both ways . It's on two 4 1/2" ball bearing door hinges and adjust up and down witha 3/8-16 set screw in the middle. The springs on each side hold tension on the table so it doesn't bounce. The table itself is 4" x22". These grinder builds are addicting. I'd build another one if I didn't have so many knives to make.
