    It appears to be the same lathe pictured on Tony’s site. It lacks the stop rod for the Rivett version of ELSR.

    The serial number (523) is the same as on tony’s site, but the photo of the SN tag...

    That's pretty cool, and the schematics look beautiful.

    Do you have a way of sharing the zip file? I'd be more happy to send some money to cover the cost of this.

    Also, if you'd like a CAD model...

    Glad to hear consensus is just sanding to adjust clearance then refinishing the sanded face. I wasn't sure how bad refinishing the sanded edge would be, glad it's straightforward. (You can tell I do...

    I have the same box, similar vintage, and the same problem. Pretty annoying, it's been that way for 5+ years. My other Gerstner is smaller and in rougher shape but has never had this problem in ~15...

    To add to what JHolland said, don't turn on the drive motor with the headstock cover off at anything but the lowest speed. It'll fling oil, even if the spindle itself is stopped.

    To check oil...

    Nicely done, I think you'll be very happy with the machine. I'm glad you bought it too, I really don't need another lathe but was very tempted. I always liked the tailstock on these; stoutly built...

    That’s an insanely good deal, assuming it works. Basically a long-bed monarch 10ee with a larger swing and D1-4” spindle. Also the vari-speed drive is a self contained mechanical unit, so way easier...

    Regarding FEA, it's not a *huge* amount of work to learn, but also easy to use it in a way that you get garbage results. If you have a CAD model already I'd be happy to run a few basic FEAs for you,...

    Confirmed you are correct. I use an E size 40 position toolpost on my 1030F. It fits the machine well. Only downsize of E is it's a less common size so haven't seen as much used tooling. But that's...

    Viscount 44 and ETD150 are both good general prehardened toolsteels. ETD150 is as hard as 4140 prehard, but stronger. Viscount 44 is an easier to machine prehardened type of H13.
