  A slower speed is required for hard material.ie. 3 to 5 hundred rpm. I use a mortise & tenon cutter, but I'm usually cuttin soft sugar pine. On sugar pine I can run it quite fast & rune compressed air. For quarter sawn maple plugs I turn it sloooooooow. How slow? Bout as slow as Fenton sweeps.grin

  Hi Fenton. I've done them just like that, on the edge to minimize waste and heat buildup. The plugs I cut were Delignit, and generated quite a bit of heat at that. The composite is somewhat less dense overall, so it may not be a problem.
