I have to break down a lot of sheet goods for cabinetry and wanted something more efficient than the track saw / table saw method I’ve been using for awhile. I’ve set everything up. The fence side of the saw is cutting very nice, cuts are coming off straight and parallel. The large sliding table is another story. I am struggling to get it square or even consistent. I have been using the 5 cut method which I have used before. Going through the process I have gotten results where the numbers show I’m only losing in the 10 thousands of an inch per inch cut. Which should be amazing. Except when I put a piece through the regular process of squaring… it’s not square. This process is cutting a straight line with the track saw, straight line against the fence for two parallel sides, straight side on the cross cut arm to square perpendicular side, that side back to the fence to rip a parallel edge… and it’s not square. If I cut parallel sides on the fence side of the table saw and put one of those sides against the cross cut arm to square the perpendicular side… but this time stay on the crosscut slide and flip the board and also cut the opposite side (using the same straight reference edge against the fence) I get very perfect isosceles trapezoids… which are really sneaky because if you just check the diagonals they are equal distance. The give away is the top and bottom lengths are not the same and they always seems to be about 1/16” difference in length. I have been working on this for days and I’m getting extremely frustrated. What could be happening where the 5 cut method gives a very good result but then cutting a new piece results in a isosceles trapezoid??? And if you want to check my math this is an actual result I got tonight that resulted in the trapezoid when testing a piece after: (A) .5000 – (B) .4925 = .0075 / 4 = .001875 / (L) 35.625 = .00005263 error per inch Is the 5 cut method not the right way to square the sliding table? Could something be misaligned on the sliding table that no matter what my adjustment is it throws off the cut? I have gotten it square a few times but my other issue is the sliding table isn’t consistent and goes out of square VERY EASILY and I have to start all over. Am I expecting too much from the saw and sliding table? I’ve noticed a few other issues like the tape measure to the right of the blade has accuracy issues, at about the 30” mark the measurement ticks jump to almost 1/32” off where they should be which is annoying.
