Folks,
I'm cutting a double tenon on the TS, with about 0.17 between tenons. Using a shop-made tenon jig to cut the space between the tenons I wind up with an inverted V shape on the bottom, sticking up maybe 0.010" (that's a guestimate).
Tried two blades: a Freud 80 toother, and a Freud 50 tooth combination blade.
Any ideas why this wouldn't be flat? The 80 tooth blade is only a year old and hasn't seen too much wood.
Thanks, Jack
