Nice one Nobby, foot motor, or electric? Should look good, with the rust gone, and a bit of paint. Ian S C

Hi Ian
It is pedal driven with a large heavy fly wheel . Encountered first problem You may be able to help or someone else. How is this 24 tooth gear removed from the end of the leadscrew ? Therse a tapped hole in the end or is it a perminant fixture ? thank you for your interest & comment

Hi Nobby,
This is just a wild guess. If the two holes in the gear are threaded then maybe they are there to draw it off using a plate with three holes in it. The middle one threaded for a bolt to press on the end of the leadscrew.

Hi Nobby, might there be a small grub screw or two inbetween the teeth. If all else fails, maybe you could take the handwheel off the other end and withdraw the leadscrew, and then maybe get a better look at how it is fixed on.

Regards Nick.

Hi Nobby

Well that should keep you busy for a bit!

It looks reasonable cosmetically so a bit of elbow grease should make a big impression.

I find this type of project very rewarding – bringing stuff back to life so to speak.

Do you intend to treat us to a photo diary of your restoration? ( please!)

Norman

Hi Guys
Thank you all for your input on this. I will have a look tomorrow there is a 1/4" whit thread in the end I will make a spacer and try and pull it off But I will have a look for grub screws etc I will try your idea John first as I recall I made a peg spanner before Her indoors has a list of jobs as well.
I had an exe lathe before but i cant recall having this problem

I notice that Tony ( at Lathes.co.uk) is seeking photos of this lathe – no doubt you will already have seen the information presented there. I guess he might be a useful contact re removing bits?

You can use an old shifter, (adjustable wrench) with a couple of stainless pins drilled and inserted into the jaws

One size fits all as you open the wrench up, an adjustable pin spanner

Have fun nobby

Hi Andy
Thank you for your interest in my latest project I had a lok at the "link" thats a brilliant Idea with the Adj. spanner
I'm off down the shed/workshop and have another go. I got in touch with Tony @ lathes.co.uk and he said it may be keyed but he was'nt sure but he said let him know how what happens
Cheers Mate

Hi Nobby

Looking closely at your photo of the gear it looks like there might be a seam between the gear and the part with the holes in. If so could the part with the holes in it be a collar that screws onto the shaft and locks the gear onto a keyed shaft. That way it would allow different gears to fitted to the lead screw shaft.

Just a thought

No sure of the protocol here, a driven shaft on the LH end, would it have a left hand thread? Or would that be on the driving shaft? Just thinking out loud, sorry if I confuse things. Ian S C

Hi Nick & Guys
Nick your idea to take the leadscrew handle off Etc was a brilliant . as you can see by this photo . I was able to get behind that gear & spacer as Martin noticed ( a seam) a light tap with copper mallet and the popped of . I still have a long way to go Bob it could go in a museam with my Drummond lathe & Drummond hand shaper

Looks a worthwhile project Nobby.

I like Ady's adjustable pin spanner

Hi Nobby, I should have realised that it was a collar with pins through the gear and into the leadscrew. Same type of keying that you get with the old Drummond and one or two other makes of lathe from that era. Martin's obsevations said it all really. I'd say the threaded hole up the middle of the leadscrew would be for a set screw for retaining it all together when in use, as I suspect that the gear and the collar are normally just a sliding fit.

Hope the rest of the rebuild goes OK and I bet it will look a nice machine when it's finished.

Regards Nick.

Hi Nick . Ian & Guys
You are right its the same system as the drummond that I have an early flat bed type.
I done a quick test today using a test bar I ground at work many years ago . Anyway the reading was
a thou ( 0.001 " )over five inches I havent starting cleaning the rust off yet as you can see
Ian you dont confuse the issue its good to have input from you

Do you realise that EXE engineering still exists in Alphington Road Exeter? see here

Not producing lathes anymore but, as you will see, still with some connection to workshop equipment. I picked up a S/H Keates V angle plate a while ago which was made by them. You can see it at the top right of this picture sitting on on the faceplate. ( The lettering which you can just see on the front of it says :- EXE ENGINEERING – EXETER)

I doubt they have any spares for your machine though – but maybe they would value a picture of your project on completion?

I recall that they bought up the last stock of Keates angle plates, and there was some information somewhere in ME for those who want to pick one up. Perhaps they stamped them with tehior name,but i'm pretty sure they didn't make them, though i could be mistaken.

Hi Guys
I have cleaned up the gears today . 54 , 33 etc they seem odd but with 12 tpi leadscrew they work out fine
the driver is 18 ie 33 divide by 18 = 1.833rec times 12 = 22 tpi . there will have to be an idle gear
