I have had this little contractor saw for 3 years, bought reconditioned and assembled. Everything about it 100% works as it should, minus 1 unknown error that has caused me concern and grief. I have spent quality time calibrating this machine down to 0.005” all around (from the miter slot to the saw blade, saw blade to the fence, miter slot to the fence). But somehow, I always had a +1/16” on some of the boards I have cut. For the longest time, I blamed my material handling technique leading me to purchase feather boards, Grrr-ippers, etc to no avail. Yesterday, I finally found the issue. When I was calibrating with the fence, I always measured from the grey metal to miter slot / blade, not the end black housing pieces. And there was the problem all along. The end housing is skewed by 1/16” ever so slightly, causing boards longer than 24” to do the 1/16” taper. I found this out late last night so will have to find out how to adjust today, but I’m sure will be no problem.
