But I came unstuck this weekend crosscutting long boards - 3" x 1" x 72". the cuts were made using the mitre gauge and a scrap fence that I tacked on for the extra support - all good but the cuts were nowhere near 90 degrees.
Now my table is within the prescribed tolerance and everything by the book or so I thought. On closer inspection the screws under the mitre gauge were loose and caused me the above problems. All 3 screws that could be tightened were in need of pinching up. This is something I have over looked and on this project did not matter too much as it was a fence/run for a dog kennel but could have been costly if I were after the accuracy one would normally expect.
Thought I might share the "gotcha".
