I guess it depends on the size and whether you can get the block out of the machine.

I've had success using a high speed bench drill with solid carbide PCB type drill bits.

When I picked up my Centec, it came with a Clarkson C type chuck and a set of imperial collets.
Until I found some metric ones second hand, I made my own set.
As far as I'm aware, all Clarkson style cutters use a 20tpi BSW thread form; The Clarkson Germany brochure claims they are made to BS122/4

Unfortunately, I've not been able to find free access to British Standards from within the GB, though it looks like readers in Northern Ireland might have access using their library cards.
Derbyshire Libraries don't seem to offer access remotely, though may do so on their own premises.

edit; I can't try it myself, but anyone with a Lancashire Libraries card??

I did a factory tour back in 2008

If you have a Facebook account, you might consider joining Home Built Belt Grinders, and asking there too.

Maybe an HSS form tool and a basic lantern chuck in the lathe
If you can find one the correct diameter, you could even use a woodworker's carbide tipped router cutter in the toolpost, as the form would then be ready ground.

I'm not sure what you mean by Chrome search engine.
Do you mean you use Chrome browser? If so, head for the settings page under the three dots top-righthand-side.
From there, there is an option to make Chrome the default browser, and also, which search engine it uses.
Sometimes during a major windows update, they try to get you to make Edge the default browser, with Bing as the default search engine, which is easy to miss after the update's re-start.
I use Opera as a browser mostly and have set it as default; that one has the option to always check if it's still the default and alert you if not.

Probably the best site I've found for old catalogues is via Archive.org
https://archive.org/details/internationaltoolcataloglibrary?sin=TXT&sort=-week

There's a similar one for Lathe Manuals

Here's a slightly larger one in use by Cliff at Wrights Scissors in Sheffield

There's several on ABE Books, starting at £150, but obviously they are still listed so no buyers at that price.

On on eBay UK at £110

But one completed last year at only £46

It's not a full capstan attachment, but Chester have THESE on offer at the moment, with a 30% discount coupon available.
https://www.chesterhobbystore.com/shop/tooling-accessories/tool-holding/multi-head-indexing-tailstock/

The MT2 version isn't particularly rigid, and unfortunately, they can't supply spare tailstock ends.
I bought that one, so I could use it in the Myford as well as the larger Warco gearhead.
Note that the various holders are primarily designed for metric sized dies etc, but obviously can be adapted or duplicated.

Not Damascus steel, but this video is worth a watch

Tamahagane: Miracle Steel of Japanese Swords
https://www3.nhk.or.jp/nhkworld/en/ondemand/video/4001416/

There was a very good one a while ago about Yoshihara Yoshindo, Katana Swordsmith
Unfortunately it's now beyond a year since broadcast and been removed, unless you can find it elsewhere

Do enjoy your new toy.
A couple of folk have mentioned the 3 jaw shown fitted.
If you're not familiar with this model, it' might be slightly counter intuitive in its operation.
The manual is HERE, it it's a GripTru with particular instructions on setting it to run true for any given diameter on p4

There were days before I was allowed to use a slide rule.

I Know I've posted this link before, but it seems an appropriate time to give it another airing.

Which Inch, does mention the 1795 brass standard length of 1m, and the later platinum one in 1799

It's a pdf download, but I've used it many times and it appears to be safe.

A little video for you; we used several different designs at work, e.g. a secure supply would feature T shaped earths, or some computer kit would be a different shape to stop the cleaner using an adjacent socket etc.



A Little bit here about the old 4 screw sockets.

Look through your older books folks,and particularly US ones.
35/64" regularly comes up as the tapping size for 5/8" BSF, in books where 14mm isn't suggested.

As examples;
My early Machinery's handbook 6th edition suggests it, though my 20th edition says 14mm
Myford Series 7 Manual by Ian Bradley mentions both 35/64" & 14mm as alternatives, like my Zeus tables.
The Amateur's Lathe, by Sparey only mentions 35/64"

Metal Turning Lathes by E.T.Westbury interestingly shows different;
So does my Speeds & Feeds Pocket Book ~ Hayward-Tyler & Co. July 1942
They list the tapping sizes for 5/8" BSW as 35/64" and BSF as 9/16"

Bill

Yes, I have used my router as a toolpost grinder;
There photos are just a mock up, as I took them to illustrate a different point to help someone on a Facebook group.





Bill

Mine are Metric version as well, but maybe an earlier one.
Since your query is about 35/64", this forum thread might be interesting

There's a number of different threads on Vintage Radio Net about them; this is one, there are several others

It might just need disassembling and cleaning out.
