Featherboards with Locking Miter Blocks

MarcElbichon presented https://www.thingiverse.com/thing:1795001 with featherboards and locking miter blocks. I really liked his featherboards, but found I needed some miter blocks that would fit a Craftsman Model 137 table saw with 5/8 inch tabbed miter slots, I also found that I needed something that could handle a bit more slop in the expansion of the locking design. His knobs were a bit small, with limited available leverage, so I designed some of those as well, using the same basic design.

I have included his featherboard files (any file labeled as "TF") as well as the attribution file from his thing page.

My system requires 1/4 inch flat top machine bolts for the miter blocks, and matching nuts for the knobs.

Design documents are in OnShape and can be copied at: https://cad.onshape.com/documents/46083cf1441521b078903738/w/204c17d6e66791d86a461f5d/e/e63800c2ea8bb090e48bbe96

Remix button is not working to find the other project, so I included the attribution file and
