Shop-made micro-adjustment jig
Build your own jig for routing precision
Eking precision out of threaded rod and scrap
Here's my shop-made version of a micro-adjustment jig for use as a router-table fence. I made mine out of inexpensive MDF to the dimensions shown. The threaded rod, which is epoxied into the grooves, has 32 threads per inch allowing you to position the fence in precise 1/32" increments. The knob then locks it in place. To make minute adjustments, just unlock, move a step, and re-lock.
