Lot 4 tailstock screw broken

 

I’ve owned this Dalton six b-4 lot 5 s/n 294 for almost 20 years. I’ve always used it gently knowing how old it is, but today its age finally caught up to me. The screw that drives the tail stock in and out broken off drilling a 1/4 inch hole. I guess it was just its time. ?The screw that drives the tail stock in and out broken in half. I’m assuming there was a crack from the keyway that slowly got larger overtime and it finally bit the dust today.
?
Is anyone familiar on this group with obtaining replacement parts? ?I sincerely doubt anything is for sale, but I was wondering if anyone knew someone that could make me a replacement? I have all the pieces so I’m sure a competent machine shop could make a replacement for me. I’m just not really sure where to go as this is always been a hobby for me. I only use the lathe 3 to 6 times a year.
 

Hi Aaron,

? ? An easy fix would be to drill that broken end of the shaft out, tap it, and screw in another threaded piece with an oversize diameter, with threadlocker. After that cross drill and ream it, and press in a pin to lock it securely. Then the new piece can be turned, threaded, and the? keyway cut. I would do it, but I'm located in Canada, and the shipping might be problematic during these times.

Jerry,

This sounds like good advice. I’m not really a machinist and really use this lathe for random repair projects.? What you are suggesting to occur to me, but is really beyond my skills. I’m more of a woodworker and a welder primarily. I was making a replacement collar out of aluminum for the guard on a jointer. I’m restoring when it broke. I’m going to see what I can find locally, but if nothing else, I’m willing to take a chance of mailing parts to Canada.I’m going to shake the tree and see what falls out. Thank you for the advice and I appreciate it!?

Aaron

OK you can repair the screw.? You need to make a replacement end to replace the broken one.? By facing off the broken part of the screw up to the larger diameter that passes through the screw in end of the tail stock.? Make a new part with a spud on it to go inside the hole you have created?in the acme thread screw.? Not sure this is all that clear but I have repaired?any number of broken or damaged lead screws this way.? ? You might be able to use a bolt to make this part so you don't?even have to cut threads.? ?You can use bushing lock locktight?and a small cross pin to secure your replacement?part.??

Hey Dennis I was just looking at the tailstock on my 9 inch dalton and I noticed it had a removable plug on it out of all the daltons I have or seen this is the only one I have.

That is a tool for greasing a dead center.

The hole on top of your tail stock is a reservoir?for white lead.? White lead was used as a lubricant for dead centers.? The pin you show does not make any sense as the dobber that was in the hole from the factory was made of brass. Dobber was used to apply the lube on the end of the dead center. Dennis

I don't know if anyone has responded yet but I'll offer a couple of suggestions.

I've been watching a good many brazing videos lately since I'll have to braze the belt guards for my Dalton lathe and a steady rest for my Clausing 111.? An accomplished welder could braze but it must be held in perfect alignment.? You would need to touch up the diameter on a lathe and repair the keyway.? Brazing results in a remarkably strong bond.

Another option is to face off the broken stud to square the end.? Find a Grade 5 or Grade 8 bolt with the thread you need, cut it to length (both ends) for a new stud, cut a keyway on the new stud and press (slight interference fit) fit it into the hole you drilled on the end of the screw shaft.? You would have to cross drill the shaft/stud for a taper pin to secure it permanently.

I'm sure you could find a replacement part but you would likely have to buy the complete tail-stock.

There are more experienced people than I on this forum; perhaps they will weigh in with a better idea.

Regards,
Peter
