    Much better for tool changes, but rigidity with 50 is even better. 5MT is 1.75" gage line diameter. NMTB50 is 2.75" gage line diameter. Not a big deal for most work, but if trying to tear off stock...

    Last place I worked in got a lot of use out of their HBMs, all 3 ran pretty much every day, and that was a job shop. But Garwood makes valid points IMO. I would definitely not want to go back to MT...

    Runout can be an issue in Morse taper machines if they've had anything spun in the spindle. That's the inside of the spindle. They can be reground if necessary. I far prefer NMTB50 spindle in an HBM...

    I only have 2 acres, but yesterday out in the very back of my yard, I spent a couple hours splitting wood from tree falls and enjoying nature and the quiet. Lots of rabbits and squirrels zipping...

    A36 hot rolled would probably stay pretty darn close to whatever it was when you started. More relevant than movement after machining would be what that plate is going to be laying on or welded to...

    Yep, would like to poke my eyes out now, thanks for getting me to watch it!

    Although 90% is high, even in a real job shop it's still probably at least 70% of work in a vise easy. The rest in my experience is either in an indexer or super spacer (including rotary tables here...

    Not sure if they were special order, but my 818 series II has a direct drive 3 HP spindle. It is a sweet machine.

    Well, obviously it's a toolroom lathe, but it seems a very limited one in terms of getting much more done than fuzz cuts and fine threading. If that is all O.P. has in mind or if he doesn't mind the...

    I'm thinking he meant go over the high places twice rather than low.

    Aww man! C'mon grunts, you could at least grease and tarp the poor thing. I'd like to grease and tarp all the C.O.s who let that kind of thing happen!

    It's sounding like if your parts are mostly collet sized work, an HLV would be a very nice machine. If you have much heavier work to do, a 10EE would be better. 1 HP is not great. 5 HP is much more...

    Yes, the stones absolutely need to be flat. That can be accomplished on the surface grinder or by "lapping" them with a flat diamond plate. DMT plates were guaranteed flat within .001" when I bought...

    Currently, I've got the 2×JT2 Valenite and 1×JT3 Valenite adapters left, along with the ⅛"-⅝" Jacob's chuck on the Narex JT3. Also the NMTB Acura- Flex, but that's not CAT 40.

    I think probably because he had one simple geometry question that he wanted to get an answer to. To do all the rest of that would require quite a lot of pictures and writing/typing.
