I reminds me of making my first carve, tring to make part clamps with no clamps
Hah, very familiar. My first carve was the airflow diverter to use so I wouldn’t lose my mind while I was carving the dust shoe next.
At least you have a shield along the rail. Now that’s a mess
I did very simple cut from the plywood first, install it temp. then start cutting real deal without these mess.
Hah, yeah, I threw together a temporary cardboard dust shield when I was making my first shoe cuts, bit of a Catch-22
Also I don’t see any reason to use 1/4" bit for cutting that material. Bigger the bit bigger the mess. I always use 1/8" single flute for plastics on fast feedrate, slowest RPM and shallower depth. If it makes sense.
