You have a good start of antique tools that are very useable. Clean those tools up, good old tools are never rusty old tools.use the tongue and blade of your square to check your mortises, the 1.5 inch chisel matches the tongue and the 2 inch chisel matches the blade.practice, practice,practice.
hi, you better cut with a saw the diagonal then get off the materiel with a 1"1/2 sharpen cisel, it's much more faster imo is your cisel have a round edge?
So can you post up somewhere either on RU-vid or Facebook the saw mill plans with some measurements please I liked your video's and your mill best of all those that I have seen to date
