I have had a Love Hate relationship with my Jessem sliding table purchase since day one. When I bought it of course I was hoping for day in day out accuracy. I have been through the set up sequence several times and I still cannot get consistent results. I do several test cuts and adjustments until it is right on at 90 degrees. I do my best to maintain consistent body mechanics as I propel the fence through the cut. Then when cross cutting several pieces to size (using a Forrest blade, mounted in a well tuned Unisaw) I get varying accuracy. I have tried using this rig for cutting tenons and it is not good results. One shoulder will be true 90 and the other side will not be.
Is there anything you might suggest that I might do differently to be able to rely on this for making repeatable door frame parts or accurate face frame parts as I had hoped? Any advice is welcome and I am willing to tear it down and start over again on setup if that is where you think the problem might be. Thank you-Bill

H,
Thanks for your question. I am forwarding it to John White.
Sincerely,

Thank you. Any and all help with this problem would get me back at it and going strong. I cannot figure out how to set it for 90 degrees and trust it at this point for tight joints.
I look forward to any future posts. Bill
It is near impossible to diagnose something like this at a distance, but here's my best guess:
The first thing I would check is to see if the table is moving exactly parallel to the blade, if it isn't you won't ever get the thing to cut correctly. To do this, clamp a small stick to the miter gauge so that it just brushes the teeth of the blade at the infeed side then slide the gauge forward and see if the teeth still brush the stick at the outfeed side.
