machineing radius edges

[phill05]

Removing the bulk of material could be done with a TCT wood cutting router bit shaft sizes go up to 12mm, could the transition be finished on a lathe.

I had a go at machineing the keyway yesterday with my less than perfect cnc designed for cutting polystyrene and although I had to go very slow and I only took 1mm cuts it did get the job done quite well, it would have been even better if I had a long enuff bit too.

Now I just need to find some one with a machine that can do the radius a bit better.

Only if the design is such that the corner radius is >= half the part width.

Which makes it a piece of round bar if its square or not doable if it isnt.
