I tried my saw out. The saw consists of heavy cast iron castings. It
does not tilt. Depth is set by moving the table up and down a slot
with a bolt clamp. The motor is a big universal, like that seen on
old sewing machines. It winds up to 16,000 rpm. The motor armature
is the blade arbor.
My two blades were a diamond face and a metal blade with a coarse rip
type tooth. I wonder if any carbide tipped 4 inch blades are rated
for 16,000 rpm?
Did your blade have carbide tips or just steel teeth?
