This is a micro-adjustable dual fence mini router table that attaches to a Dremel 3000 rotary tool. The first pipe section screws onto the collar threads on the tip of the Dremel, the other pipe section should be screwed in tightly to the bottom of the plate (and is intended to be left there permanently).

Screw the lock nut onto the bottom pipe, then screw the top pipe on. Each full turn adjusts the table height (and therefore the bit height) by 1/16 inch. So micro adjustments can be made, for example 1/4 turn is 1/64'th inch.  Once adjusted, turn the lock nut so that it is tightened onto the top pipe segment.

Attach the fences to the plate using two copies of fencescrew1.  Then screw the other side of the fence (the hole over the slot) to the appropriate sized bean (bean1 for the first fence, bean2 for the second one) using two copies of fencescrew2.

The scale for the main fence is calibrated in 1/32 inch increments, which measures the distance from the center of the router bit to the closest point on the fence.  The two longest scale marks are at 0 inches (where the edge of the fence crosses the center of the bit), and 1 inch from the bit center.  The secondary marks are 1/8 inches, the tertiary marks are 1/16 inch, etc.

With the second fence attached, both fences can be adjusted to squeeze onto a piece, which should perfectly center it over the router bit.

This version uses fractional inches. Two further versions will be provided that support decimal inches and Metric. OpenScad source will be made available at that time.
