Wow, thanks for all your work Allen that is indeed impressive. I know for a fact that the Mikini spindle would have stalled within .5sec or almost immediately on contact with the part with that .25 DOC and probably would have stalled within a second or two with the .1 DOC. I have actually stalled a .5 rougher with almost exact parameters (.1 DOC, .5 WOC, S1800 F11) in steel, I had to adjust to .05 DOC F8. I would not even have attempted .25 DOC. I forget the details right off but I can do a .1 DOC full slot at around S2900 F19 but it is with a 3/8 variable flute endmill and it is still loud as hell, but it makes it and to my surprise has yet to chip the flutes (because it has a .03 radius). I want to do this conversion but it will have to wait for some funding. Any plans of trying to integrate LCD panel back into operation?
