    He contacted me. The issue he's having is using the P values to coordinate upper and lower Turrets for pinch Turning. I haven't done it in several yrars and obviously wasn't standing in front of it....

    It looks like a lot of moving parts. Not enough to justify the maintenance.

    I'm sure a lot of it is glitz and glam, especially the robot arm. Ox makes a good question about doing side work. Also...

    WTF are you talking about? Do you have a reference that says these come with pre loaded programs to finish AR lowers? That's questionably legal. I would be willing to bet Haas would NEVER give that...

    Okay, I really like Kennametal's DF series. Others do not!! They are very loud if you're running them right. You need to get coolant through the Drill, no exceptions. I would start at 3/4 of the...

    I'm assuming that "bolt" is Norwegian for blank or something, and not a Fastener.

    This is not a difficult hole to make. Drill it as big as is realistic, then use a Boring bar and finish the size...

    It's good practice to do the best possible for initial ops. But it's most important when you have subsequent ops. If that's the only thing that needs to be done--fuck it.

    Why not use local? No idea where in Utah you are, but Western States Calibration (30 th South SLC) has done very good work for me. I sent my Interapids to LII. But my Blake, Federals and B&S...

    But that's assuming the parts don't turn into a Potato Chip after Machining them. I spent hours with a Vee block, Indicator and Dead blow getting my parts Round. They were perfect* in the Machine.

    Honestly!! I don't ming this specific thing that much either. It can be really entertaining. I've had to work with junk equipment a lot, and had to make good parts on it. BUT it's the asshats that...

    Might as well use a file or a spoon.

    Plunge milling is about moving material fast, not slow-doesn't make any sense. Use Gregor's advice with 30% step over, 100 IPM isn't weird.

    Why not just use a Drill toolpath? Select points and drill.

    IMO your Speeds and Feeds are painfully slow. I'd probably start at 600 SFM (3056 RPM). And feed at .0175"(53.5 IPM). But if I used...

    Good lawd, nary a man born hence 1944 is going to get that reference. It would be an awfully good memory, and a drab, dull lifestyle to boot, if they did.

    It isn't Politics. Obviously. It's sentence structure and punctuation. It's the use of proper conjunctions with olde timey queens English.
