Super accurate crosscut sled

Nice sled. That fine-adjustment wheel is a brilliant idea. I’ll have to use that sometime.

Thanks AdrianT. I’m afraid i didn’t do a very good job of explaining how the mechanism works. I plan to do a blog detailing its construction when I make my box joint jig. I hope to do it within the next two weeks.

Remarkable! I LIKE! I’ve been wondering about how I am going to built a really accurate sled and you’ve just given me some really good ideas, suggestions, hints, etc. This is on my “next 5” list for sure. Thanks. I CAN DO THIS NOW!

Sweeeeet !!!!!

Dave, really great idea on the adjuster. If I may be sold bold … the 5/16-18 rod gives a movment of 0.055 inches per single revolution. The 1/4-20 rod gives a movement of 0.050 inches per single revolution. Since one is pushing (unscrewing) and one is pulling (screwing), the difference 0.055 minus 0.050 or 0.005 inches, is the movement of the fence for one revolution of the adjuster wheel. ... very accurate adjustments for truly fine tuning the fence. Thanks for sharing this as many of us will put it to good use.

This is one of the best crosscut sleds I’ve seen. Fantastic job… I might be stealing this soon.

Thanks everyone. I thought long and hard about how to make my own micro-adjuster. The two different pitched threaded rods provided the perfect solution. The hardest part was figuring out how to join the two different parts. I first tried to turn and thread a rod, but had trouble getting the two halves concentric. I decided that the threaded inserts would be the next best thing. As an added bonus, it provided a thumb wheel for tool-free adjustments.

Would like to see photos of this in use, on your table saw. Hope you’ll add some photos.

Unique design and well done.

Nice sled. Very original adjustment. I like the extension to the width of the sled.
Sorry for being dense, but other than the original sled setting, what do you use the adjustment for?

Ralph: after the initial setup, the adjustment isn’t used anymore unless the jig becomes misaligned. If I had made the jig so the adjustment wheel could be easily removed, it could be reused on other jigs.

First, awesome design! Second, I have the same question as Ralph…. did you leave the adjuster on for future recalibration? Is your top hardboard on top of ply or mdf? I love the handles, very smart and easy way to keep the hands out of harms way.

-- Sneaking up on the line....

I just had a flash of inspiration/understanding, and I know how the adjust mechanism works! Sort of like a turnbuckle, but instead of both in or both out, it’s one in/one out, at different rates, am I right?

Seems super simple to build, too – one through hole and 2 inserts?

-- My broker promised me he would treat my money as if it were his own. Trouble is, he did.

Too bad you can’t use it elsewhere. I wonder if a universal adjustment can be made with that mechanism.

Love the idea. I’m sure we will be seeing these pop up for different applications. I have only one suggestion that would take this over the top… Pentagon adjustment knob. One flat = one thou!

Well done!
