I have a cheapo scms from B/Q, I've never been happy with the "detente" so I resolved to make a device that would guarantee the angles I required,I removed the plastic insert and "copy routed" a hard wood substitute blank.

After plunging the blade through the blank, I then made a guage to be a snug fit in the kerf cut.

Next I made an angle guage consisting of a 90/45 deg angle.

When the two guages are used I get a guaranteed 90/45 deg cut, simple but effective.
