The other small problem is the T-square is hard to tighten down and maintain absolutely square. The white paint which is thick, peels off under the clamping surface in the first couple weeks, which leaves the clamp a little slack, so the fence will move with some pressure from , say a full panel feed. There are two set screws on the inside front of the T-square fence that adjust the squareness of the fence and also the clamping force of the handle. They must be tightened together almost degree by degree to keep the fence from moving left or right as the clamp handle is locked down. Just a little work with a dial indicator and I have a little less than +/- about .002″ total movement from square at the out feed end of the fence as the handle is clamped down with satisfying clamping force.

I put a magnetic base and a dial indicator on the square T-guide tube, which is magnetic. I can use a board against the saw blade and fence to set the position of the fence and then move the fence with the dial indicator, say exactly some few thousanths of an inch. Lock it down. Run the board through and get exactly the difference removed. Finally freedom from the tyranny of fractions! And my parts just go together with what ever tension I want.

With the addition of a narrow kirf, high TPI, teflon coated carbide blade and a zero tolerance saw insert, I get at least a half horsepower cutting speed improvement and panel cut quality I only dreamed of before the Biesemeyer. All hail!!
