I finished rebuilding the half nuts for my Logan 10" lathe. This process should work for other small lathes like Southbend or Atlas Craftsman

Good Idea. I was going to bore out the worn out half nut threads just enough to remove just the threads. Then bronze braze the half nuts and set up a fixture on the lathe to thread them but it's complicated. It seems I'm better off redesigning the half nuts so that threaded inserts can be easily replaced without gluing them together. I wish I had the original dimensions to these half nuts. It would really help.

This is such an awesome idea. Could you have made a shoulder on both sides of the bushing so it's pushing the shoulder against the half nut body when you're threading in either direction?

Hola hermano buen video arregle las medias tuercas de mi torno seguí el mismo procedimiento pero tuve que repetir porque la primera goma trasparente que tu muestras estaba muy liquida, y se despego al hacer la primera rosca , pero luego tu muestras al final del video una pega gris que sacas del torno compre después la pega gris porque era mas solida con este me quedo genial y ya rosque mi torno es un Colchester clausing . Saludos amigo y gracias por tu video.

Wouldn't recommend using steel, a softer material is much better because it is a lot easier to remake the nuts than to replace the lead screw. Probably phosphor bronze would even better as it is self lubricant, but I guess brass is just right if you are a hobbyist.

Hi Richard, I have been using my original set for over a year now with no issues at all. They still work just like when I installed them and show minimal wear. They don't see daily use, but I would say quite a bit of use considering I am just a hobbyist. Probably about 3 days a week I am using my lathe. I will put an update video on my channel if I ever run into trouble with them. Thanks for watching!!
@richardcox34856 жыл бұрын
Hi, I have started on a set for my Atlas but one thing I am having trouble with is how deep to make the thread, having trouble finding in the handbook. Do you happen to remember how deep you made yours? have watched part 1 but don't recall you ever mentioning it.
@BuildFixCreate6 жыл бұрын
Is it an 8 TPI leadscrew? I believe standard acme thread depth is 0.5*pitch. So if it is 8TPI the 0.5*0.125 = 0.0625 But you need to know what the minor diameter is that you bored it out to as that will affect it a little

13:41 I feel dumb but, why do you need to clock the brass insert to the dial? To make sure when the dial is on a whole number, the distance between the half nut and the dial allows the nuts to close up? As an alternative (for me for instance I bought replacement half nuts for my south bend so I can't clock them) ..... if I run into trouble, I could shim out my threading dial to achieve the same end result -no?
@dizzolve5 ай бұрын
10:00 Since Logan makes half nuts for this lathe and since they must be clocked ....... all half nuts must come cut in the same clock orientation?

seems the oil holes are missing or you filled them with epoxy My lathe uses almost the exact same setup but it has oil holes that allows you to get oil directly into the nuts

I don't believe you have to "clock" the half nut when you glue it in. Your thread would just start when you engage the half nuts.
@BuildFixCreate6 жыл бұрын
It's not really about where your thread would "start". It is so that your half nuts engage the lead screw at one of the lines on the threading dial and not at some random place between the lines. Sorry if I didn't explain it well enough.
@daveanderson80626 жыл бұрын
No no. You explained it well. My point being, when you engage the half nuts at a line it's gonna do the same thing every time. The line may not be 100% perfect, but it wasn't on ypur clocked example either.
@CraftedChannel6 жыл бұрын
Actually, I replaced a threading dial gear without considering this clocking issue and when I lock up the 1/2 nuts my threading dial stops about 1/8" off the tick mark. When they build these lathes they engage the 1/2 nuts then take a cold chisel and strike in an indicator mark that lines up with the dial/feed rod combination as randomly clocked at assembly. The video producer is right on target. This is absolutely required if you want to clock into the mark in your threading dial. I own at least 10 different Atlas lathes and they are all ticked in different places.
@BedsitBob6 жыл бұрын
Is there no provision for adjusting the alignment of the threading dial itself? Alternatively, you could make/attach some kind of reference mark (maybe a dab of paint) to the body of the threading dial unit. Also, why not make the nut with a shoulder on both ends, so there's no tendency for it to be pushed out, whichever direction it is travelling?

This is a great video and I definitely something I could have followed to restore the worn half nuts in my Boxford Model C (similar to a South Bend or Hercus 9"). I had considered other ways to "restore" the thread including soldering and re-threading but none of them seemed viable bearing in mind the difficulty of having the two half-nuts already split into two parts. Yours is definitely the best solution as it provides an entirely new thread but re-uses the existing half nut mechanism. Nevertheless I have (for the moment at least) managed to delay this restoration task by a simple modification to the half nut pivots - I've machined new pivots with an eccentric part which now allows me to adjust the half nuts which was previously not possible. It might even be that some of your viewers wish to go the whole hog and do your repair AND add the means for adjustment. In case you are interested here it is kzbin.info/www/bejne/nqXSmWOKm5aNfMU
