I just got a mill (well not delivered yet)
I have a set of 12 endmills for creating the channels.
Now from what I understand I drill a hole with a drill. Stick me end mill in and start taking off small layers. From the indo above it seems to indicated I can go 1.5* the diameter of the endmill down. So for a 1/8th endmill I can mill 3/8 depth? Seems a lot.
BTW Fixittt the slot mills I mentioned in my "Hi from me" thread, have two cutting blades where as endmills have 4 cutting blades (according to a fitter and turner whos worked for many years as a fitter and turner)
Also Is there such a thing as going too slow? I wouldn't have thought so but I'm going to be cautious and practise a lot.
