They may be able to make up a nut and feed screw for your Roundhead Regal lathe. Not a big shop, and they seem like reasonable folks from what I've There is a shop that does make new feed screws and nuts for the South Bend Lathes. I'd remake the screw out of "Stressproof" or maybe 4140 or 4340 steel.ģ. Large valves and sluice gate operators around the hydroelectric plants, and we used aluminum bronze to handle the higher thrust loads. I would go with something a little harder/stronger than ordinary 660 bearing bronze. The nut can be made from a chunk of hard bronze bar stock. With a roughing tool and another for finishing the threads can cut that thread in a lathe. A good machinist with the time to grind a small boring bar LeBlond likely hadĪ special set of taps (roughing and finishing) for cutting the threads in the cross feed nut. Local machinist (a kind of semi-hobbyist sort, or a retired machinist with a small shop) and ask about having a new nut and screw made. Write off any ideas of getting a new cross feed nut and screw from LeBlond, unless you have a side-entrance into Fort Knox's vault. A worn crossįeed screw will only wear a new nut, and things will start off as sloppy (or as nearly so) as they were prior to replacing the nut.Ģ. Replacing a cross feed nut without addressing the cross feed screw is going to make things a little better, but not fix the root cause. Chances are if the nut is that worn and broken, the screw threads may well be knife-edged in areas seeing the most use. They are not so accomodating as Hendeyman or Logan, nor are there the huge numbers of new old stock (NOS) parts or good used parts available on ebay (or similar) as there are for South Bend or Logan lathes.ġ. On the other hand, the heavier LeBlond lathes are supported with some parts and drawings, as I learned in dealings with LeBlond when I worked at NY Power Authority.Īs noted by G.Wilson, LeBlond Ltd, if they have a cross feed nut on their shelves, will charge as if it were made of unobtainium.
LAGAN LATHE CROSSFEED DIAGRAM SERIAL NUMBER
They have some information as to when a particular serial number lathe was built or shipped, but not much else. I do not think LeBlond supports Regal lathes that pre-date the "square head" Regal series.
