My personal experience was wonderful, Clive

I will find my previous thread for you, but am also very happy to discuss by eMail if you wish.

Just a thought, Nigel ...

Another option would be to make a significantly smaller diameter spindle, and bush the headstock to suit.
You already have bigger capacity lathes available, so perhaps the EW could be usefully adapted to suit more delicate work.

... I expect Dowty would be pleased to see that  ‘generic’ bonded seals are  not being marketed under their trade name.

I am reviving this thread, to post a  **LINK**

https://www.ebay.ie/itm/Levin-Watchmakers-Lathe-Filing-Machine-Clock-Tool-Attachment-Filer-Die-/172822040549

The item is already sold, but it is worth a look if you are interested in building a ‘machine filling‘ attachment for a small lathe.

The design is by Levin; but, given that his book is rather pricey, it’s perhaps worth studying the ebay photos whilst they are still accessible.

Thanks for the link, Martin

Some interesting items there ... but ‘condition is everything’ and it’s too far for me to travel to view.

Please excuse the stupidity of my previous edit

I was, of course, barking up exactly the right tree !!

Nice ones, Neil

That rings a bell

I won’t spoil Sam’s fun though.

1. Yes, Scotland Yard ... Hence the slightly tenuous relevance to my ‘security‘ recorder
2. The 7 segment display on your calculator contains a cypher

I bought a secondhand ‘surveillance’ video recorder a few year back, Sam ... only to find that it was password-protected.

It didn’t take me very long to guess 1212

Thanks, Nigel

Yes, I think that must be the one.

Funny, that ...

What I read in 4.14 was about sample dimensions, depth of immersion, ultrasonic power, and duration [and more] ... all packed into less than one page.

That, together with the documented results was sufficient to convince me that you would be wasting your time [and that of anyone who steps forward to do a 30 min test for you].

... and if that is the best that can be done, then the Print edition of MEW remains my choice, and archival storage my responsibility.

I am well aware of that ... which is why I pointed you to 4.14

It happens to us all, Pete

Too late to edit:

This is a useful reference to Avago sensors: **LINK**

Dated 2006 ... so there may be a newer version available

That should give you plenty of time to read this, John

The Wikipedia page gives a useful overview: **LINK**

I may be back later
