Accuracy is everything when doing fine woodworking. Unfortunately I’ve never found a reasonably priced, accurate device to make very tiny adjustments on the tablesaw. The old tap tap method is frustrating and too often inadequate to get super accurate cuts. This easy to make and use device incorporates a Kreg microadjustment turnscrew (around $20) made for a router table. It clamps onto the tablesaw using two clamps for stablity. You could make your own too but this one was just to simple and reasonably priced to pass up.

For the record, the heavier duty DeWalt clamp on the right is by far the best of its type I’ve tried.

A threaded screw insert that fits the Kreg device’s screw was placed into the block of wood that sits up against the tablesaw.

This one is made to fit over the measuring device of a Sawstop. Your device needs to be sized to accommodate your own tablesaw.

To move the tablesaw fence closer to the blade, you release the tablesaw fence, turn the adjustment screw clockwise, then gently push the fence into the adjustment device then relock the fence.

To push the tablesaw fence away from the saw blade you first release the fence, turn the microadjustment screw counterlockwise and then relock the fence. That’s it.

In seconds, you can make adjustments that pretty much just take off a layer of dust from the workpiece.

yeah a micro adjuster is a great feature on a ts fence,much more accurate that the fist bump method.

looks like a good inexpensive method and I agree with constant micro adjustability that’s why I have the Incra TS-LS fence on my unisaw.

Very well done! I was thinking the same thing as Petey about using a magswitch base to make it universal. Thanks for posting :-)

I’m a fan of the Irwin quick-clamps like you have in your pictures. Knowing your prefer the DeWalt though, I’ll have to keep an eye out for a couple to try.

Thank you, I spent almost an hr last night trying to get a tounge to fit in the groove. I was think I needed away to move the fence just a couple of thousandths, and then yyou show up. I order 1 2 mintues ago.
Thanks Joel.

-- Joel, People ask what I make. I tell them I make sawdust, and now and then a nice box or frame,or clock, or lamp pops out.

Thanks for the kind comments.

Mag Switch – I use them and love them. One might work. Two will surely work and would be lots quicker to apply than a clamp. The big concern is stability of the device. It has to be rock solid. If you knock a single Mag switch it can move a tiny bit which would defeat the purpose of the device when aiming for moves of a few thousands of an inch.

Incra fences – These are awesome devices. They provide amazingly accurate and reproducible settings. The 54” version of the fence you mentioned does it for over $1,1100.

Clamps – The biggest difference between the Irwin and DeWalt clamps shown is thickness of the bar. The thicker bar does cost a bit more to manufacture and buy. But the difference in strength makes those few dollars worth it. In retrospect, I regret buying the cheaper versions. For $10 more the DeWalt is a pleasure to use. It provides much greater clamping pressure and much less concern that it will flex and move the pieces I’m trying to clamp. If it flexes, it’s to such a small degree that I can’t see it.

I was thinking two mag switches. I learned not to bump the stop from cutting wedges (segment bowls) with a miter sl (incedra 1000hd) so I use two mag switches with a stop because you can bump them. I am going to make this -thanks again for posting
