I tried with my Incra 1000SE and had similar problems. It is very difficult to get the same length and angle. I used a sled and with a coupe of trials was hitting it right on.

Can you take all the pieces, stack them up on their back edge and look to see if there are any that are out of spec?

That’s one of the first things I checked.

They are all identical.

Too many variables. Miter gauge not perfect, saw cut not perfect, and human not perfect. Any combined error is multiplied by 20 cuts.

For what its worth, I like to do the segmented glue-ups like that in halves, sanding the final joint flat to its mate, eliminating trying to get everything perfect. I imagine there’s nothing wrong with your incra. I think its compounded problems. Wood tear out not allowing a perfect seat on your fence, stuff like that. Also is the vernier scale at zero too?

I like to wrap a tie down strap, or a band clamp around all of the pieces.
I think that gives you a better idea of how much its off and also where.
That could tell you where you need to adjust, or where the problem may be coming from depending on where its off.

Maybe this will help. https://www.youtube.com/watch?v=QzV-o4_kacc&t=26s

You’ll get a better answer from Incra than you will get here.

If I had a do-over I would not purchase the HD1000.
Mine had a broken part in it (which Incra quickly replaced) but the one I got was terribly out of square and only after taking all the adjustment range out in a counterclockwise rotation was I able to adjust it to 90
90
should be in the center of the range IMO.
Even though its heavy it does not feel robust, just big heavy and unbalanced.
I find myself still reaching for the stock miter gauge and using the crosscut sled.

Ok, I’ve had mine for over 10 years. Works perfect. I’d ask a couple things. First, i’m going to assume the 90 is dead on, so the issue is only in the angles. Is the 45’s dead on, checked with a machinist 45? Second, when you use the detents are they in the very bottom of the groove. Second check that you don’t have some little bit of sawdust in the groove as well. Finally that vernier scale can get challenging to hit just right if its off a few degrees.

I had some similar issues, in the beginning but stuck with it, and used clamps to hold the material consistently and it helped. Check you rail. It should be tight in the slot. That will give you a slight variation. They wear and expect to change them every few years.

One final comment. Not knowing your blade, cut your first cut close to the line, and then shave the final cut off. You could be getting a slight deflection in the blade.

Mine’s monkey nuts dead on.

What you have is a tolerance stack up problem, not a miter gauge problem. First of all, you will never be able to consistently cut things in such a way that the end result has zero error. Even if the gauge is 100% accurate, your technique and equipment are not. You didn’t assemble the thing like one would normally do. What you did was to put the entirety of the error in one joint. Typically, all pieces would be clamped together at the same time with a strap or band clamp. That would allow the error to divide itself among all the joints instead of forcing it all into one. The clamping pressure would make the tiny errors disappear. Your stock is quite thin, making proper clamping difficult. If I were going to make a lot of those, I would make a glue up fixture.

I have used an Incra 1000HD for over 10 years building multi-sided boxes and accuracy has never been a problem.

I tried it again, but I used a nice piece of baltic birch ply.

I also did a test fit with a strap clamp, and it looks to be spot on.

So I guess I’m good to go.

Dang, Charlie. Nothing like my feelings about it. I think it is wonderful! Within a few days of having it, I lost track of where my original equipment miter gage even is, let alone ever reach for it.

I’m curious: what table saw did you try it out with?

I recently bought the HD1000 and the Miter Express. After complete setup, it is dead on. The 1/10’ vernier takes a little time to get used to, but once you read the addendum they add, and do it once or twice, it is really simple.
I actually was able to set it up to 11.25’ yesterday afternoon, and laid out four rings, 16 segments each of walnut and yellowheart, zero light in the seams on all four rings when dry fitted with band clamps. Glued them up and happy, happy, happy.
One of the secrets seems to be able to cut the segments the same exact length every time. I use a block with magnets in it, up against my table saw fence below the blade cut. I slide it up so I can measure from the blade to the block, then bring the block back down so the block is not in the way of the cut, but sets the distance. Run the wood off the Miter Express to the block edge, then push forward from there into the blade. I can measure to 1/64th of an inch with this system, using a calibrated rule.

Had mine for several years and would not give it up. Can’t say enough good things about the folks at Incra and their products.

I know I am in a tiny minority.
It just started out bad for me and I guess I have just never been able to get past it.
The end of the plastic piece in the sliding stop was broken off at the screw hole.
I found it when that piece slid out of the stop because neither screw was tightened.
There are 4 screws that hold the miter, you loosen those to adjust for square. I managed to get it square but I had to twist hard counterclockwise, there is absolutely no more adjustment available in that direction.
Loose screws, broken part, required adjustments on every parameter….just wasn’t what I expected when I paid the $$$ for the Incra.
Incra replaced the broken part after I sent a picture and I didn’t have to return the defective one.

You know if you buy something from Harbor Freight you have certain expectations and when you buy something from Incra you have certain expectations…..I feel like I got the Harbor Freight experience with the HD1000 instead of the WOW this is better than sliced bread experience I was expecting.

My saw is a Delta 36-714 hybrid, I have adjusted it so it is square, straight, and true.

I get excellent results with my Incra, but I have learned that there are many parts of the cutting operation that can subtly alter the angle. This compounds when you try to complete a many-sided polygon..

The one trick I use for “perfect” joints is to cut the angles the best I can, and if there are an even number of sides I’ll do the following:

Join the segments together forming two halves of the circle. I like using blue painters tape stretched across the joints to pull the miter dead tight.

Now unless everything is perfect, these two halves will not join perfectly together. I place each half circle on a board that runs against the table saw fence such that the blade will take a small trim off of each end of the half circle (use double sided tape or toggle clamps). This establishes a perfect cut at 180 degrees which will mate perfectly with the opposite half.
