Bob, that is the early type. When you tighten the star wheel under power it rotates, the later type does not and has a different clutch assembly. The early type tends to slip if you don't tighten it up whereas the later one really gets a grip even if you only just nip the star wheel.

Hi all have stripped the saddle down and I have found the problem the 2 half moon chevrons that fit inside the clutch are missing does anyone have any idea what size they are and what they are made of or who can supply new ones I think the number is 52 in the catalogue

The left hand bolt in the end of the star wheel is also missing does anyone now what thread or who could supply me with one thanks

These parts appear to be available from Boxford for not (too) outragous prices. Seems there are a few variations, though, so yo will need your serial number to get the correct parts for your machine.

On my 1964 Southbend there is a spring clip on the inside end of the clutch. Most peoples seem to be missing whenever i see photos of southbends, also missing from the 1942 one i have nearly finished putting back together., Does the boxford have such a clip?

The clutch appears to work fine without it though.

Hi I have found my lathe was made in 1951/2 being a mark one .

the part I want for my lathe clutch plates part number 3656-64 ( half moon ) are not avalible from Boxford does anyone have any idea of sizes so I can get some made.

Or is there anybody else who sells Boxford parts I've made contact with the Boxford forum thanks

[Old ElanParticipant @oldelan]

You could try John Ward at http://www.latheparts.co.uk/

I recently bought a cross slide screw and nut from him.

Excellent quality and well priced.

[BazyleParticipant @bazyle]

I don't think you nee to be too precise with them actually. The curve I just so the fit the hole and don't rattle too much. In operation the bit that does the job is the centre part of the curve that jams into the bottom of the clutch cylinder. If the diameter is too great it catch at the sides not the centre and if it is too small it will twist off line.
The diameter edge is rounded off to fit the groove in the central operating rod.

I think a few experimental cardboard ones will soon find the fit if nobody has one in pieces to measure.

Exploded view of clutch assembly

"Half moons" in position

The half moons on my BUD are the same size as the "floor" of the clutch brake halves, i.e. when lying flat inside the brake shoes the flat edge is flush with the brake shoe edge

Here are the dimensions of the ones on my lathe

The inside diameter of the brake shoes when in position in my machine is 1.180" which would be to OD of the half moons (near enough)

Both the straight and curved edges are well radiused as described by Bazyle

Hope this is of assistance

[Mark CParticipant @markc]

I think if you make the OD to fit the clutch cups you will find it works OK. I think they are are about 1/8" thick (3mm) and as Bazyle mentions, just make them progressively smaller until they sit at the correct angle (by eye will be good enough)

Hi All what good hobby we have when so many people help a fellow modeller I would like to thank everyone for the help and kindness shown to me on this subject ,

With all the help I will be able to bring back to life a old girl of 67 to do the job she was ment to thank you. just a afterthought has anyone restored the half nut ( imperial ) for screw cutting

[mark smith 20Participant @marksmith20]

I`ve been meaning to restore the half nuts on my spare southbend 9A. Havent got around to it yet but once ive figuring out how to clamp the half nuts for boring out the old (whats left of them)threads ,it should be pretty straight forward. I`ll be using the method popular in the USA of making a threaded bobbin out of bronze and gluing and pinning it into the half nuts before sawing them apart..

Like sort of described here:

Heres a photo of the half nuts that need repaired ,they are in fact boxford ones but fit perfectly in the southbend.The proper southbend ones are on the right which are on my good lathe.

Lovely post I feel I would try to set my half nuts in my beaver mill and remove old threads but I would have a problem cutting the nut before splitting so over to a local machine shop I think

[ScrumpyParticipant @scrumpy]

Sorry I should have replied to Mark no there is no spring

[ScrumpyParticipant @scrumpy]

Hi All I have been told by Boxford they have the clutch plates after all , last week these were not avalible but after another search they have found a set .

Does anyone have any idea what size and pitch the left hand threaded bolt is thanks

[larneyinParticipant @larneyin]

Hope this rough and ready sketch isn't too dark

Looks as though the thread is 3/16" x 32 BSF

[ScrumpyParticipant @scrumpy]

Hi thank you so much it came out fine Derek

[ScrumpyParticipant @scrumpy]

Hi After getting the clutch plates from Boxford I have spent the most frustrating morning trying to fit them you want 3 pairs of hands and extra eyes but I succeed in the end, designing a rubic cube must have been designed by Boxford

Ps how do other people do this job there must be a easy way

[AjohnwParticipant @ajohnw51620]

I think that there may be some info on working on the apron on lathes co uk but under southbend. I've not looked at it so no idea how useful it is.

Some people strip the saddle when they first buy the machine and clean it up etc. Mine was a little sporadic but worked fine after the feed had been used a few times so I left it alone.

Having done this a number of times, I don't think there is any "easy" way. You just have to struggle – I expect with practice it might get easier!
