To Build
Sled
I really like the Mattias auto-stop feature. After cutting the box splines, it would also be nice if I could drop in some 45° blocks to hold a box.
I need to rebuild mine. The one I have is both too heavy and not as useful as I'd like. The next build should have longer tracks. I think I can use a much thinner base for the bottom of the sled. I'd also like to put in a stop this time and better saw guard. It should be sized to contain that blade at it's max height with a decent padding (~1/4" all the way around, so 3/4" wood). I like the box joint indexing tool I saw.

Pushers
I like the I-Build-It ones
I'd also like to make a Micro-Jig style: https://www.youtube.com/watch?v=9ZdJEEyZ07w
Should have 3 legs. The right two ride on the piece of wood and have high grid sand paper glued in place for grip. The right most leg will need to be very thin, ~1/4", so I'll probably need hardwood or sheet metal. The left leg moves up to parallel with the other two so it can also sit on the wood, or it can drop down up to 1.5" for stability. The back needs an overhang. I'm not sure if this should be adjustable. It would be hard to make it adjustable on the right leg.
Feather Board

Stand
The saw stands up on it's own, but I'd like to make either a stand to fit under it, or a stand that it can sit on (with the legs folded up). Top will collect saw dust and the rest should be storage for all the jigs and attachments.
It might make more sense to use a finger board than a feather board. It might also be nice to be able to support it from the top too.
Zero Clearance Inserts
Make a few at once.
