Hi All,
A friend of mine wants me to cut a complex shape in basswood, including a lot of sharp edges and corners. These edges vary randomly in direction relative to the grain.
I have no real trouble with cutting smooth smooth curves with ball nose tools. My problem is only the sharp edges and corners. It seems like there is always at least one grain direction where the router leaves little uncut bristles. I can't seem to get rid of all that "fuzz" - without hand sanding.
I'm assuming the keys are sharp bit (maybe straight flute for chip removal but minimal tearing) - relatively low rates of cutting (depth, stepover, ipm) - high rpm. I think another component is sequence of cuts, but I'm floundering.
I'd like to know if it is possible (or practical) to cut basswood cleanly, without needing significant sanding (and maybe sanding sealer). Does anybody have any suggestions, please? [Maybe I should just go back to hardwoods (only).]
Thanks for your attention.
