Glen,

I bought one of those Rockler micro adjusters. I cant resist a new gadget. Its an illness. In theory it should work but the magnets arn't strong enough to keep the thing from moving along the fence rail. It hasn't gone into the trash yet because I'm sure I'll find some use for it.

What I do with all fences that need to be micro adjusted is to position the fence, and make a test cut. Clamp a block of wood up tight against the fence and losen the fence and then use a paper shim between the block and the fence to sneek up to your cut.

You probabaly know this but Incra sells fences that allow you to adjust the fence in and out by thousands of an inch. They of course arn't cheap.
