I am wondering if anyone has done tests to see if it is better for no friction or friction. I can see both sides. Friction could help hold the router on it’s cut but would defeat the counterweights purpose. A low friction would allow for smoother movements and reduce any jumps or drags.
If frictionless is the way to go then what are the solutions. Several coats of polyurethane, marine paint, a good sanding, or change in material (I.e. melamine, acrylic, or metal all would have low coefficients of friction).
