I received an incra miter sled for Christmas. Put it together last night. The sled isn’t PERFECTLY flat on the saw table, so it won’t be perfect 90 degrees to the saw blade. With a digital angle gauge I see the sled lays about 0.3 degrees off of horizontal.

Do you guys that use incra miter sleds adjust your blade to make it vertical to the sled to account for that when you use the sled? Seems like a nuisance to adjust the blade each time to use the sled then adjust it back so the blade is perfect vertical to the table when not using the sled. i’m relatively new to woodoworking, so who knows, that may be standard operating procedure. Or, there may be some step I missed in set up. Any insight appreciated.

Thanks.

Mine sits flat. I would inspect it to see what might be causing it NOT to sit flat.

This should fit flat to the table, no doubt. Unless there’s an user-assembly issue (always have to keep an open mind about this …), then contact Mark Mueller (mark@incra.com) to discuss the issue – he’s excellent, and is committed to getting user questions resolved. He will either find a quick solution or have the unit replaced.

Pictures may help in diagnosing the problem.

BTW, I’d start by seeing if it sits flat without the miter gauge attached. Perhaps it’s not so much of an issue of sitting flat on the TS as much as its the workpiece not sitting flat on the sled?

MJCD: yeah, tell me about it, I’ve bungled assemble before, so i’ll check that.

To the eye the sled sits flat, it’s not like it’s visibly heaving up or not flat and parallel to the table saw top , but when I zero out my digital angle gauge directly on the tablesaw top then place the gauge on various spots on the miter sled panels, i get a range of readings from 0.25 to 0.45 degrees. That’s the issue i’m experiencing.

If I read some of the responses correct, you guys get the same exact angle reading when taking the angle on top of your miter sled panels as you do when measuring directly on your table saw top?

Thanks for the quick responses guys, very much appreciated.

I get variances like that just placing the Wixey on various parts of the table saw itself. I bet you do too.

Cosmicsniper: yeah, could be the digital gague, but I also used a precision square (pretty good one, from woodpeck) and when I place it on the sled panel and check for vertical to the blade, I see a sliver of daylight near the top of blade indicating the panel is not perfect 90 degree to the blade…but I know with 100% certainty my table saw top is perfect 90 degree to the blade as confirmed by both my digital gauge and precision square.

also, i really don’t think it’s my table saw side wing causing the problem because when I assembled it (11 mo’s ago, brand new sawstop), I used a veritas 36” straight edge to get the wings perfectly flat and parallel to the center of the table.

Hmmm…in that case I think I would give Mark a call…after double checking that I assembled it correctly. :)
