Topic tags/keywords: table saw t-track miter slot miter bars sled crosscut sled tablesaw

Say you’re going to build a table saw crosscut sled.

You want to attach a couple of miter bars on the bottom of the sled to fit in the miter slots on your table.

You also want to use a few t-tracks on the top of the sled to be able to attach different things.

You find a great deal on a large quantity of t-track.

Is there any reason you couldn’t use some of the 3/4-inch wide by 3/8-inch deep t-track as miter bars on the bottom of the sled instead of buying additional 3/4-inch wide by 3/8-inch deep miter bars?

Thanks in advance for helping a newbie.

In theory, if it’s the right size it should work.

I think the challenge will come in the actual sled build, specifically when attaching the sled surface to the runner. When I make a sled, I put the runner in the miter slot, then position the surface on top, and attach the surface to the runners with screws. That’s the step that could cause a hiccup in the sled build.

I suppose you could put the T-track runners down and attach them to the side surface with double sided tape, then carefully lift it out and screw the runners to the surface.

There’s no reason not to try…if it doesn’t work out, you still have the T-track for other uses.

we tried that in shop, but for some reason the rocket scientist in charge of relocating once used seem to hit it on every thing, and put gouges and nicks, making it a tough slide, ended up with the high density plastic guys, worked a whole lot better

happy days

If the miter slot is exactly 3/8” deep, then the bar should be 1/32” to 1/16” less in thickness. You don’t want the bar to be the same thickness as the slot depth.

It seems all the miter bars and t-tracks are 3/8 by 3/4 so the miter slots should be 1/32 to 1/16 more (either 13/32 by 25/32 or 7/16 by 13/16). Right?
