re: New mitre sled

OK I’m very happy about this. I just got a chance to do my 2 tests and they both passed with flying colors.

Picture frame is very tight. It’s scrap ply 3-1/4 × 16 or so. I figured this sort of larger test size would reveal any imperfection in the fit. I’d say it’s about as close to perfect as can be.

The triangles are cutoffs from the picture frame. One from each side of the sled. They also line up very very nicely. It passes the finger test – line up the bottoms and run your finger up to feel for a change in height between the 2.

So it looks like my idea of starting with a nice, square sled, squared up against the table saw fence while attaching the runners was a good one. This gets the front of the sled square to the blade and allows for use of the speed square to line up the mitre fences. I think that’s more accurate than most combination squares. I guess I got the idea right the first time, but just executed it poorly. This guy, on the other hand, makes me very satisfied.
