    What are these dedicated lathes or dedicated units you guys are always referring to.

    To me a dedicated machine would be used in a production type environment and set up with fixtures, stops, maybe form tools and then run by an operator with limited skills. The machine would be left set up this way and adjusted by the set-up man until the entire job has been run thru it.

    What is your meaning?

    If by a dedicated unit you are referring to a real lathe that is designed to do many operations quickly and efficiently.

    I hope you don't mind me calling my leblond lathes and my gorton mill "real"
    When someone drops by my shop I show them my two 3in1's then I show them my real lathes and mill. I guess I shouldn't mention them on a 3in1 forum. But I do still use my 3in1"s every once in a while. And it is interesting reading about how some of the machines have been rebuilt and redesigned by their owners. You guys have done some amazing rebuilds.

    Keep up the Good Work
    and Good Luck

    dedicated

    As in lathe dedicated to turning. As in mill dedicated to milling. Or reference to a machine or object designed for a singular purpose or process which may or may not be capable of other purpose or process.

    barrel

    Final polished shank is 1.20 inches which works fine with the four jaw chuck for threading or simply facing off the chamber end. Sometimes I thread using the four jaw chuck....sometimes with a faceplate, dead center, and dog.

    Like I said, a real lathe is a very versatile machine

    You can also mill on a lathe, if the work is small you can hold it with the tool post with the cutter in the spindle. You can also use a milling attachment.
    Or even a Versamill in the lathe. Or milling cutter held between centers, work held on cross slide or saddle. There are many ways to get milling done in a lathe.

    And you can turn with a mill. Work goes in a collet or chuck in the spindle,
    Cutting tool held in a vise, move the table for cutting depth, raise and lower the quill or knee to make the cut or fix a compound to the table. Not the ideal but it works if you have a mill and no lathe on some work.

    Dedicated units as you call them would be my first choice now that I own and have had experience using both my 3in1's and a lathe and milling machine.
    But everyone has their own preferences and will buy what they want. If they want a 3in1 nobody will talk them out of it. And if they are set on separate machines nobody will talk them into a 3in1.

    Good Luck

    Nine years

    I know. I've been using a south bend lathe and bridgeport mill for nine years. Occassionally I work with a turnmaster lathe.

    The shoptask is for home use.

Which can be done with a reamer to fit the needle bearings. Also the shaft needs to be turned down. So I don't see any difference with the gearing or any reason to change it due to other design changes.
    On the older 17 20 models, the 31 rpm kit was a couple of extra pulleys that you put between the motor and the center idler. After they went to the hi-low spindle brake design, there was no room for these pulleys. The gearing assembly is pretty much the same on all the machines, just the spindle rpm has changed.

    "Most of my threading will be for rebarreling Mauser actions for custom rifles."

    if you are going to be threading rifle barrels on your new shoptask, you might as well start checking your wheel bearings and tire pressure on your trailer, you are going on a little trip to vagas soon.

    First Shortblock you have to buy a machine to do that. To bad JT changed the color you can't take pictures of his machines anymore . People will know for sure this time. As for the red mine was red first. But you didn't know it was just primer.

    Glossy red primer?? Yeah Right. Even if there was such a thing, only a fool would try to paint green over it.
    C'mon Digital- Fess up. At first you were just trying to make a copy of the red patriot machine. Now you are mad because they changed the color.
    As far as all those supposed defects are concerned, none of those pictures show any thing in any detail and are no proof that you even took them. How about some pics with you holding a copy of the day's newspaper.

    fastlanecafe your another one of those people claiming to have a shoptask. It's time to put up or shut up guys. The red machines showed up after I posted my pictures not before.At least I can prove I own one you just talk allot and no show except pictures of JT's machines. Your pathetic and you need to start proving what you say. By the way don't you think green and blue is a better color than red anyway.

    This guy's lips must be shaped like a shoe for all the times he has stuck his foot in his mouth. Trying to tell people on a machinery forum that you use glossy red primer under green paint- who do you think your're kidding. How about tell me the name of the paint company, because that stuff is an exact match for the paint on my patriot.
