Thanks for your input lads,
Its a mine field out there. I thought I had my work cut out with Cambam, but the different types cutter seems even harder.

You'd think some one would right a book for us newbies so we could get our heads round this new fangled hobby.

I thought building the machine was going to be the hard part, but its the other way round.

I agree with you Silyyavski, a 2 flute cutter at 1/8 to a 1/4 would be a good starting point, but I've never been told to run something until it breaks and then decrease it by 5% until it doesn't.

What happens when the bit snaps. Does it fly out in all directions. Are there any precautions I should take when attempting this undesirable act.

I'll have a go at that and let you know the outcome.

Thanks again.

Michael.
