All good thoughts, thank you sir.
I struggled with the cutting speed trade-offs but slow speed and continuous air on the cut sounds reasonable. Your comment regarding air as both cooling and chip evacuation tickled my memory. The photo below is my small Leitz universal horizontal mill normally used for squaring up stock.
There's an air line magnetically attached to the column of the mill, directed at the cutter to blow off chips. My thought was to mount a ten-inch woodworking blade on the arbor (not the slotter shown) clamp the Delrin to the tombstone, make four cuts, rotating the part after each pass.
But this is over-kill and would require quite a bit of time to set up. Besides, the cut probably wouldn't be all the way through anyway and would have to be finished off on the bandsaw.
So I'll stick with the band saw, if it seems practical. Any comments about the blade configuration and pitch ? 8 inches is a lot of plastic to cut through, might require more than a few wedges
Thanks !
