This tenon jig is a copy of one by R.J. De Cristoforo. I saw it in one of his books about 12 years ago. I don't have the book anymore so I'm working from memory. The original design was for a miter slot, but it was easy enough to re-engineer it for use with the sliding miter table (SMT) on the Ryobi BT3000 table saw. I've goofed around with the design a couple times and I feel the current version is simple and practical.
