60cm square will be plenty. Do you have any example profiles that I could cut with typical corners etc? If so then send me the drawings.

I will pm you my address.

Do you have any preference on the cutters that you want me to try cutting it with? Like I said before I have some 3mm carbides with 3 flutes but I am finding that you have to run these at very fast feedrates to get anything like the correct chip load. I am sure 1 or 2 flutes would be much better.
