Hi there,

I recently built a CNC Router after watching varous videos online & for the last week or so ive managed to mill a couple of signs and engrave a few patterns etc. It has a few teathing problems but overall ive been surprised at the modest success i have had.

While testing the beast ive been using some cheap old router bits i had knocking about but would like to now tryout a few end mills etc. Im a little confused on how i go from my routers collet which is a fixed size to various sized endmills. Do i litteraly need a new collet for each and every size I require? Sorry I know its a daft question, its just there are so many on the market I find it confusing to get my head round.

Thanks in advance

Oh yes one more thing, any recommendation on where to get 10mm bore collars to hold my leadscrews in place?
