    Moving jaws only have a jaw on one side, the center holder has jaws mounted on both sides. That is why the center holder can't do both.

    But, can the dovetail center jaw holder be tapped with the 1/2-13 holes to mount normal jaws?

    He includes a center jaw that is just a plain old smooth jaw (think hard jaw). And two hard jaws to bolt to the slide jaws (old-skewl style) to mate that center jaw.
    That is the only reason for the 1/2"-13 jaw bolt holes under the talon-grip strips in the slide jaws.

    Yes, kinda.......
    The right hole ends up being very shallow because one, it gets in to the hold-down bolt. And two, there is a bunch of meat missing to accommodate the dovetail feature.

    Well, you don't need much meat there as it is only in compression really.
    Just holding it from sliding around.

    Again, the 4-inch bolt pattern will fit on one of those skinny center hard jaws, I checked it out and the bolt depths are good without hitting anything. Then you can get "extra wide" (6") jaws for the 4" pattern all over the internet.

    That fixes nothing for me. I would still be making all new jaws, or putting the 4" bolt pattern in existing jaws
    At that point, I'll just switch to dovetail (like I already did).

    So, a hard dovetail insert with 1/2-13" threads in it won't work?

    Sure would (you give up its thickness). Who has that? I don't have time to make it. I'm running already..............

    Just replying to the other folks asking about putting a bolt pattern on the center jaw. Or maybe I was misreading!

    In the process of re-arranging the shop. Not wanting to follow in our boy David's footsteps:

    img_1398.jpg

    That ingress is about 4" behind the front of that drive. Which means I have to run my fat paw past the battery plug at least 4 times!
    And, pull 4 stiff #4 THHN's out of there. Dumbest place possible for that stupid plug!

    "Now is not a good time, leave me alone for a little while!" LOL

    Is this the real place the term "buzz kill" came from?

    Just about the last chunk of iron I would want to bring in here, came in here end of last week:

    img_1390.jpg

    The short of it is: I need another 4th equipped mill real bad. And, I had to pull the 4th out of the big-fat-haas and revert it back to pallet-changer.
    With VF2ss prices being in the tank right now. And, a guy I trust having a well equipped 4th ready '06 for sale. It was financially the best option.
    This new (to me) unit will be better suited for random jobs than the other one (with a 4th) which is once again now committed to final OP on the production parts.
    So, I pulled the other, and parked this one exactly where it was:

    img_1392.jpg

    Then: the Brother and the lathe were shuffled around. It gets awful tight in here when that 22k lift wanders in (the floor survived, thank god!)

    img_1391.jpg

    And finally, the 2 that was pulled outside was brought back in and set facing the Brother forming a cell.
    So far, this is fantastic having those two machines arranged this way.

    img_1394.jpg

    img_1395.jpg

    Then I proceeded to attempt to kill myself over the next 48hrs running power/air (and parts!).
    I am wasted now. And, today will be spent at the desk programming the next parts waiting to go in the new pig.
    It looks nice and roomy in here in the pics. Trust me, as I filled it back in with tables, cabinets, carts, etc, it became quite cramped.
    Not, to cramped to be functional. There is a clear 2ft path around everything. So, two guys buzzing around in here is no problem.
    But, Pit-Stop access without moving tables is out of the question now.

    I bought a 4k sqft building recently to move all of the non aerospace and xometry work over. Didn't have 3 phase either.

    The power company will do the 3 phase install with my paying the horizontal lines boring under the road for $5800 and a $3500 transformer differential to have a pad mount instead of above ground.

    Wonder if they could do something like this for you?
