    This is what I do. No stock prep for aluminum or plastic, cut a 60° dovetail for titanium or pre-hard steel. Quick swaps on center between the vise and collet fixtures.

    I run 1000PSI TSC through the collet while cutting so it stays clean. I blow it out a bit and give it a spin by hand between tools.

    I have a few DNA-11's for 1/8" shank tools. They work pretty well. I don't remove the collet from the nut.

    Not if you don't tell them what it is. Usually people post an actual problem or question, with a descriptive subject line.

    My thinking is it's a Yamaha R6, (or R1 with dual contact), not an F-350. It's a lot faster and it corners real nice, but if you're moving sacks of concrete take the truck.

    Digitals are the easiest to read. Also the easiest to mis-read when you don't notice it's zeroed wrong or that it skipped a bit due to coolant. I find I get the best readings from dials, until...

    H11 IS a tolerance. Your scenario was throw a part at a guy and ask him to make it without a print, and you ridiculed the concept that they had the gall to ask for a print. Yeah, if you bring in a...

    If you hand me a part and ask if I can make it I will ask for a fully dimensioned and toleranced print (or a model that includes tolerances on every dimension) before giving an answer. If you don't...

    That's a hobby machine, and as such is against the rules to discuss here. That said, either use a flycutter or take multiple passes with a much smaller solid carbide cutter.

    A 3" indexable is probably too big to run on a VF-2 in 4140 prehard with good results unless it's a shallow finish pass. You have a Yamaha R-6, not a Ford F-350. I'd use a smaller solid carbide...

    Better rigidity is always better, all else being equal. It also tends to be more expensive. Is it worth paying for, for your parts in your shop? That's up to you. It can also have some...

    I run 15K for hours on end in Titanium for finishing small surface details with a 1/32" ball. I'm getting a quote for a Toodle so I can run it faster.
