Once I got the fence running smoothly, I needed to have a more accurate way to set the fence. The fixture uses two wood blocks. The 1st block has a 5/16”x18 bolt with inserts in the block. This block moves the fence in or out depending on which side of the fence it is placed. The second block has a 1-2” dial indicator mounted to the second block of wood. This determines the actual movement in thousands of an inch. Note that both blocks have rare earth magnets attached to the bottom of both blocks to hold them from moving. To use this fixture you set the fence close to the final dimension and lock the fence. Next place the block with the bolt end against the fence. Next place the end of the dial indicator with the travel about half the way on the dial. Then zero the dial. Now release the lock on the fence,turn the bolt clockwise while watching the dial on the indicator until you reach the desired distance. finally make the cut. This sounds complicated until you have done it a few times. Comments are always welcome. Thanks for looking.

I love it, Jim. That makes the movement of the fence so accurate you don’t have to keep making test pieces of critical parts!!!!!

Very interesting. Do you find those magnets to be strong enough to not worry about slipping? Where did you get them? Thanks for posting.

I like the use of the magnets … most TS tops are cast iron and magnets make very good use of that property. With what you have done precise setups can be logged and reused at a future time to duplicate a part!

I am going to adapt this to my cast iron RT top as it could use a little more precision too!
