Colleagues: I run a SawStop ICS with a Colliflower zero clearance throat insert. The Colliflower insert has replaceable inserts to accommodate various blade kerfs and dado widths. For those not familiar with Colliflower products: http://www.colliflower-zci.com/
Problem: inserts are a mystery “wood” or some other man-made material. Colliflower claims the inserts are MDF, but the screws holding the inserts in place do not hold and easily strip out. Tried “reinforcing” the screw holes with Crazy Glue, but that did not seem to help.
Measurements show Colliflower inserts are ¼” thick. The local Home Depot carries small pieces of ¼ MDF and ¼” plywood, which is not a “true” ¼”. Would screws hold better in the ¼” plywood and a masking/painter’s/duct t tape shim would bring it up to ¼” thickness?? Am apprehensive about the 1/4" MDF.
I also thought of ¼” both sides smooth Masonite, but no one around here carries it.
Can anyone think of any other material that would work? Thanks for any suggestions.
