I have a Millers Falls No.214 sawset that appears to be similar to the Stanley 24? I have two questions for the saw sharpening gurus. 1) How do you determine how deep the plunger should be in relation to the teeth? 2) My sawset has a flat plate with serations that adjusts in and out that is below the anvil and plunger. It looks like it is used to stabilize the saw plate. What is it for? How do I use it? I have searched here but can't seem to find an answer that I can understand.
Thanks for your help.
