I pulled out my trust TS-aligner (see my review below) and I was done in no time. Not a single test cut needed! And I KNOW I am dead balls accurate.
I also had to make a new cross-cut sled because my old one no longer fits the miter track layout (uses both). Again, it was a piece of cake with my TS-aligner and I KNOW I am dead balls accurate
If you don't have one of these it's REALLY worth looking into one.
Of course no affiliation, blah, blah, blah. Just a VERY satisfied end user.
Got questions let me know.
(NO, this was not an invitation for Leon to blast me.) ;^)
