Hi Good Peoples,
I decided to build myself a new table saw Cross Cut Sled as per this woodwhisperer video 146 - The Cross-Cut Sled - The Wood Whisperer
All was going brilliantly. The base was cut to size, the runners were installed and I had cut the two fences. They were square, flat and true. I partially cut through the base and fitted the fence. (Shown around the 8 minute mark on the video.)
I then checked the accuracy of the work. The fence was so close to 90.00 degrees to the blade it was not worth adjusting. The fence was also 90 degrees to the base of the sled. Bloody hell. I had got it right and so close to perfect it frightened me. :oo:
Time to complete the next step. Drill the extra two holes and properly fix the fence to the base permanently.
:o Loads of four letter words! :doh: The fence is no longer square to the base. Played around with shims and eventually get it almost right (but not as good as previously.) Then I made the first cut. :(( The fence is no longer 90 degrees to the blade. Its so far out of wack it will reach Pluto soon. :~
I am pretty sure the problem had something to do with the final two screw holes and the tightening of the four screws. The question is how do I stop that from happening again? I have puttied up the holes so can redo the back fence but want to get it right this time. Suggestions please.

Why/how did I stuff this up?
