I have a need to make fine adjustments when using the table saw and thought that the Incra Positioning fence would be great cost and setup limitations (moving the table height of both tables mainly) caused me to think of other ideas.
Along came the adjustable collar, If it could be used vertically, why not horizontally. I designed many jigs, most with precise dimensions and metal supports for repeatability, but simplicity won out.
A 2 by 2 and a few seconds in the lathe. I would guess if you used a 4 by 4 there would be no need for the spacer underneath. And yes, I use the collar set screw to hold the collar in place.
I made a test cut wanting 2 5/8" and the caliber said it was 2 45/64.
Moved the collar against the fence and clamped it in place, loosened the fence, rotated the collar 5/64", tightened the fence and made my cut.
I had taken pictures of the calipers showing the before and after boards, but the display wasn't clear.
So how is this a solution?
-Cutting miter runners for sleds.
-Making precise width dados without using shims. Set the blades narrower than desired. Make one pass, measure the precise width, adjust the collar and make a second pass.
-Make those cool filler pieces demonstrated on the Incra video
Additionally you could use it to make repeated length cuts by placing it on the other side of the fence. Cut a dowel, drill it in the middle to accept a 1/4 20 bolt and then attach that using a T-nut to the fence. Slide on the collar.
If anyone is curious, the little white arrows on the collar are cut from a refrigerator magnet ( made lots) so that I can move my reference point easily.
Hmmmm, thought I new how to post pictures in the body of the topic??? Anyway, just read to a pause and click on a picture,
