I just ordered a new Lead Machine from partstore. This is probably something I should have asked before I added it to cart, but how exactly does the high Z mod from openbuilds actually work? I realize this is a very basic "explain like I'm 5" question. Can you use standard endmills or do you need to buy extra long bits even for short jobs? If you are using a long bit, wouldn't deflection be a major issue and massively reduce your feeds/speeds? I'm hoping to work with some pretty dense hardwood, is that going to be okay with the standard Makita or will I need a spindle? Thanks for your help.
