How straight does a tenon saw plate and tooth line need to be to cut square cheeks? I imagine it has to be next to perfect.
I’ve refurbished a Disston 14” tenon saw and installed a new saw plate from Blackburn Tools. The original saw plate was non-restorable. The plate is seated in the spine well. The spine had been cranked on at some point in it’s life and I did my best to straighten it. Very carefully. I made a lot of improvement. I removed a twist and straightened the tooth line quite a bit. However, a very slight “S” curve remains. I might work on it some more, but I don’t think it will ever be next to perfect.
What do you all consider necessary amount of straightness in your tenon saw plate for good joints?
