  • Thanks for your concern. It turned out very nice.

    This isn't one of those little "wank" lathes, so it is very rigid.

  • We have a couple of LeBlond's in our shop. My question is how to date them.

  • Leblond still keeps records on most of their old machines. If you call them with the serial number, they will have all the info. Mine was delivered to Westinghouse Electric in June, 1943.

    I hope you dont need to buy parts from them though. They are scalpers to the max. I make and sell the

    2 1/8-5 TPI chuck backing plates on ebay.

  • Thanks for the compliment.

    The material is drill rod.

    The completed threaded section will be milled into a gear

    cutting hob, then hardened.

  • Good old lathe sure don't make em like that anymore. Nice looking LH thread too!

    New lead screw?

  • @JohnnyGadgets81 Sorry I took so long to answer you. No, making what i hope will be a gear cutter.
