The part you've shown goes between the two halves of the clutch, it pushes it out of engagement, hopefully my photo this.

Michael Gilligan - thanks for posting that link, they are easily the best and most useful photos I've seen yet of a Pultra headstock stripped down.

Much obliged

Colin

Great idea, shows that there's a use just waiting to be found for all the random items that we collect over the years.

Great design, and looks to be superb workmanship.

Colin

That's a fine looking clock, fair play to you for taking it on.

Interesting use of the graver, I'd have been tempted to form the dome on the end of the bar, and then used a parting tool to part it off, but your method has worked fine. Good work.

Colin

Phil P -- thanks for posting your excellent and very clear drawings.

I am thinking of making a pair of these collet blocks, and maybe a third one in a cylindrical form. Can I ask - did you make them, and did you make any changes that were advantageous?

I was thinking of using Jason's idea of making recessed nuts, for instance.

Thanks

Colin

Welcome Martyn.

You'll certainly get plenty of good advice on here.

If I'm not mistaken, I think I bought a Pultra lathe from you last year.

Colin

That looks excellent, very impressed, top job.

That looks excellent, very well done.

No problem, i was just going to post this, mine is quite different, and all the rest of my 17 series have just the usual screw drawbars.

I only have one of the 17 series with the lever headstock, and suspect it's different to yours, but I'll go have a look this morning.

Colin

A nice choice of colour, looks good, do post a picture when you've finished.

Here's one of mine in probably the same shade of green.

I'm doing this on my phone, and clearly haven't got the knack of rotating the pic to the correct orientation yet. Bear with me.

I don't have any experience of Multifix motors, or brushless dc motors either, so can't help on that, sorry.

Colin

Hopefully these drawings etc will help, but your manual from Smart & Brown should be much clearer.

My first attempt at uploading pics, so this may go horribly wrong.

That's a good question, I'll have to go and have a look in the morning. I've only got one with the quick close lever on the headstock. Just to muddy the water, that one is a 1770, but with the large bore headstock, it is listed in the catalogues of the time, it takes the 20mm collets, same as the 1590 models. Think they are 19.7 mm by 1.666mm pitch. Much like Schaublin W20 collets.

The Mardrive doesn't take up much room if you can arrange it into a cabinet and fit it underneath the lathe.

Or in one of the under drive cabinets that Pultra sold, with drive to the left, drawers on the right, and room for your legs and the clutch pedal in the middle, quite neat.

Colin

That certainly is an unusual tail stock, I can't see anything like it in any of my Pultra parts catalogues etc.

I don't think it looks like a Pultra part that's been modified either, but it looks nicely made and fit for purpose (as far as I can tell from the photo) , so well done, you'll not regret buying a Pultra ! I believe I've got eight, at last count, they may be breeding ?

The compound slide looks a bit modified, but as long as it's functional, who cares. Someone must have done it for a reason.

Hope you enjoy using it, I'm sure you will.

What you need now is a nice Mardrive or similar motor/countershaft arrangement.

Colin

Good work Russ, thanks v. much.

Thanks Chris, for bringing this auction to people's attention. I only live around 10 miles from the auctioneers premises, but wasn't aware of it.

Been and collected my purchases today, just 6 lots, nothing special to note, but I am pleased to say I found the company to be very pleasant and easy to deal with.

Don't know if anyone got any bargains ? can't see a list of sold prices on the website.

Colin

Useful information, thanks for taking the time to post this Chris, appreciated, Colin.

Wow ! Brilliant job, very inspiring.

I will definitely have a read of the build diary.

Colin

Thanks, Colin.
