Tail Stock Stud Removal

Can someone please tell me how to remove this stud from the tail Stock? I have managed to remove everything else but not this stud and I would like to remove it so I can clean and inspect the brass wedge and it's seats.

Thanks in advance.

Would you care to share any details of the machine????

My apologies, it's a Boxford BUD. According to the serial number, made around 1972.

Martin,

Look at this picture of Boxford tailstock bits:

The stud next to the rule is the bolt you are referring to. So if you lock two nuts on the bit you can see then you can unscrew it from the inside thread. If you are not familiar with the method of locking two nuts on a thread to remove a stud, then post again.

Edit - just thought, beware that a previous owner may have Loctited the other end of the stud, in which case you may have to heat it to break the seal   while its warm.    It having been in a fire doesn't mean it won't be stuck!

Cheers Robbo,

Thanks for that, I forgot to add the model. I must be asking to many questions if people are starting to remember me. Lol.

Lock nut method is the route I will go down, I know this method and was going to try it if I did not get a response. Due to limited funds at the moment due to purchasing the lathe, some other bits and the price of parts for these, I don't want to break anything. And I don't have lathe to make one at the moment. Lol

The picture was taken as a response to a previous thread from an owner who needed to make the parts for his own Boxford - a picture being worth a thousand words.

Don't want to give the impression I produce pics at 5 mins notice!

Why not remove the stud plus the two bronze pinch collars? They should just pull out once the tailstock barrel has been removed. It would be a good idea to download the BUD parts list from the web - **LINK**

I may be missing something blindingly obvious here, but isn't there a second bronze piece below the one in your photo, seen on the underneath of the tailstock casting?

If so, surely tapping the end of the thread downwards will extract both stud and bronze part downwards.

The two brassy coloured bits should be free to move in the hole in order to clamp the tailstock barrel in place.

If it's a blind hole, so the parts won't punch through downwards, straight through the casting, then I guess you need to pull them upwards using a length of tube, a washer and a nut on the end of the stud. Since you've not got much thread to play with, you might need to pack it up several times.

The earlier Boxfords had the casting slit and this stud was used to squeeze it tight on the barrel. This version just bored out the top of the hole to take a single bronze clamping bit. Improvement at minimal cost not seeking perfection.

OK, so different to the diagram in BobH's link then; that would explain the problem, so don't try just pulling it out then. Unfortunately this forum's software won't let me edit my previous post.

As Bazyle says, the details changed. The stud is tapped into the bottom of the hole in the casting, so once it is removed the bronze insert(s) will drop out.

I would have expected your system to be like the myford with two brass pinch pieces that hold the barrel in place usually taking the top brass securing part out, lets this all come out

Robbo,

I am not angry just very disappointed. Why do you not have all pictures to hand on everyone else's matters. Lol. I was surprised and thank full that you had that to hand.

Bob H,

That was my plan, it has not been well looked after so I am doing a full strip down and clean up, a lick of paint and some oil should last me a good few years.

Just to confirm, it is one brass collar that slide out. For those interested, I will follow up with some pictures. Of my progress now the stud is removed.

Thanks for all the help and comments peeps.

Your children have interesting play apparatus

You should see what they have to play with in the workshop. lol

They love the tressels, a few planks and a sheet and they are hunting in the forest. lol
