My Perfection miter box has 11 settings on it. Each is marked with a letter. Starting from the left the letters are M, P, H, O, W, R, W, O, H, P, M.
The question is, “Do you know what the letters stand for?”
Extra credit if you know the associated angle.
I know at least 2 people on this forum that know the answer.
M= miter or 45*]
O= octagon or 22.5*
W= window sill pitch or 9*
R= right angle or square cut
I don’t remember the other letters but the are all degrees of cut angle.
The H on the far right is for “Hand.”
What’s the prize for getting them right? 
Case of books. That’s what I heard anyways.
that is not a young miter saw…
M - Miter or 45 degrees
P - Pentagon or 36 degrees
H - Hexagon or 30 degrees
O - Octagon or 22 degrees
W - Window or Door Sill Pitch or 9 degrees
R - Right angle or Square cut
wow guys, who knew???
I don’t think so I used a table saw for hand modifications.
