Hi, I am new to the forum. I did some seaching and could find an answer to my question, so I am posting this to see if you can help me. I am having issues when cuting a groove with my dado blade. I have a 2X1 inch board. I want to make a centered 1 inch groove to the board. The way I am setting up my cut is that I set my dado at 3/4” width, leaving 1/2” space to the table saw fence. This way make a pass to the board against the fence, flip it 180 degrees and make another pass to get my final width on the groove. The issue I am having, is that the groove seems to be cut at a tapered height, 1 mm off. (I do multiple passes to insure i did put pressure to the table saw and get a paralel cut) so when i flip the part and repeat the tapered cut, the groove is not flat at the bottom, it shows to small steps at the end of the board.
I have been trying to understand why this happens with no luck. I use my dado with a zero clearance insert and make sure is completlyl flush to the saw. Also I don’t see an abrut change in the depth on the groove, it seems to be increasing constantly as I push the material thru the blade.
any comments I am going crazy and can find a reason.
