I do not remember where I was shown this, but it sure works to check if your SCMS is cutting square of not.
You do five cuts, and by the time you have finished the fifth cut, if your saw in not square, you will see the problem multiplied by 4.
I started with a piece of plywood about 10" square.
I numbered the sides just so it would be easier to keep track
I put the #1 side against the fence, and cut on the #2 side
Turn it and cut again (turn counter clock wise)
and again
]
and again
The fifth and final cut
I checked it with my machinist square, and it was dead on.
This may be old hat for many of you guys, but I use this when I have to check the SCMS.
If the saw is out even a little bit it really shows up with this method.
This old Hitachi CB8F is sure a good saw. ;D
Cheers!
