45 degree mitre crosscut jig/sled?

Both Jeff Gorman and Charlie Lieb had good stuff on their websites. Don't have the url's for you, so you'll have to DAGS.

I made a fairly large, heavy duty one that has a single runner slide on the supporting jig. The blade stays vertical.

The jig is simply a 45 degree sled with 'T' slots for clamps to hold various widths of boards. The board to be mitered is registered against a 'fence' on the near side. This insures a 90 degree alignment of board to path of blade. The clamps hold the work piece to the jig. You first cut your work piece to just over length and slap it in jig and then push it through the blade.

The first cut throught the blade also cuts the jig to fit the blade.

Voila! 45 degree miter up to the width of the jig. Length of board can be a bit longer (sqrt of 2 times x) than the height of ceiling above table saw...or move it outside for the really ambitious projects.
