I bought a Stanley 150 miter (mitre?) box off the auction site. I *think* it has all the parts. Took everything apart, evaporust on all the screws and doodads, and it cleaned up rather nicely.
This is my first vintage box, and I'm not 100% sure how tight the sawplate should be seated. If I get the clamps installed I can drop the saw plate in from the top, maybe a 1/16" gap. My engineer's square says its dead square sitting there, but there seems to be too much play at the top to guarantee a square cut. Wondering if it is set up correctly or not.
Second question would be the vertical adjustment. There's not much room in between "too tight to move" and "cast iron falling on the workpiece". Any tips on how to adjust the vertical travel? This seems related to my first issue of getting a square cut, as the vertical piece wants to fall down too far for the saw's back spline to rest on the guides.
Forgot to take pictures but can add some later.
