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.
Pushers
I like the I-Build-It ones
Feather Board

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.
Tuning
I think the blade is not square to the miter slots. Need to get that aligned correctly.
