Help Making Miter Sled

The T-Miter track goes into a dado (top of ply). The runner doesn't
(bottom of ply). Both have to be parallel.

And if you want it wider, make sure youre table saw fence is parallel
to the miter slot and use the fence as your reference.

Ahhh..that makes sense...I just couldn't think for some reason.

Mount runner for miter slot, cut to length, flip and use cut edge on
fence to make dado for t-miter track.

Thanks for the help!!

Thanks for posting the link below. Great easy to understand
instructions for building a sled.

Make the miter-track fixed at one end and adjustable at the other, then
fine-tune it when its all put together?

Put the runner on the bottom of a sheet of plywood. Make sure the plywood
extends past the blade of a table saw.and trim off the excess. Now you're
left with the edge of the plywood parallel to the runner and you can mark
for your miter slot based on this edge.
