In the latest edition of Good Woodworking I had a very nice review for my cutting gauge.
I had completely forgotten about this as I gave Andy King one to test about 2 years ago. He did say they were a bit slow! Still better late than never.
I've changed the design a little as the rear doesn't have the indents any more. They were a nice idea but not necessary in practice and the guide looks all the better without them.
The knurled knobs are nicely made for me by Phil Edwards.
