I recently bought a new miter gauge for my tablesaw. The miter gauge I chose is the Mite-R-Excel made by Jessem.
Overall, I think this is an excellent tool.
The bar is easily adjusted to fit the slot through snugger bars. There's three of them adjusted by turning a set screw on top of the bar in three places. Each location has a brass plate that's bulged out somewhat by that screw causing it to take up any play between the bar and the slot in your saw.
The head attaches to the bar with a very accurately machined brass bushing and rotates very smoothly, no catches, no slop. Just a good smooth motion. The head has semicircular plate on the top with a series of brass bushings through which a pair of pins is pushed. The main pin locates the head to the bar in 5 degree increments. The second shorter pin can be used to offset the gauge from your chosen position in various amounts of offset either right or left in 1/2 degree increments up to 2.5 degrees one way and 2 degrees the other way.
If you choose, you don't have to use the indexing feature. There's a spot in the head to store the main indexing pin if you want to use manual angle selection. The marks for indicating the angle look precisely cut into the aluminum.
The handle is a large aluminum round with knurling to provide a good grip. It holds the head very securely in your chosen position and provides a good size handle to push and pull on.
The fence is an aluminum extrusion with a flip stop on top. At the left end is a short piece of fence that can be pulled out and allow the fence to support a 36" long piece while using the flip stop. Of course you can use the gauge to cut something longer, but then the flip stop has to be out of the way.
Everything about this gauge is fully adjustable, very nice machined and finished. All parts fit together extremely well with no play, just smooth action. I suppose this is all to be expected for the money charged. Woodcraft charges $220 for it. I got mine when they had a sale going on.
The last thing to say is that the one I got from Woodcraft had an issue with the indexing feature. I contacted Jessem about it. I had thought they'd send a new part to correct the problem, but Dan Sherman at Jessem chose to send me an entire new guage. The whole process of resolving the issue was handled very quickly and entirely to my satisfaction.
Again, the tool is excellent, accurate and appears to be of the highest quality. And Jessem's service is absolutely first class. I just couldn't want for more in a tool or manufacturer.
