Phil P:

Thank for posting the link!

MichaelG:

Thank you. I'll measure again with greater care!

In accepting the imperial measure I may have been influenced by the understanding that one of the pre-decimalisation coins was exactly 1" in diameter.

Bring forward the tailstock with thread rolling die/head attached and form the thread. (I bought a Russian made M1.2 thread roller on ebay for £13.01 inc. postage from St. Petersberg. Fantastic value for money.)

...

I couldn't immediately find your "thread roller" but did see a Cyclo item at nearly £100 and that without rollers; I have put mine in the safe!

I make the penny 0.8" in diameter ie not metric?

MG and SOD - thank you. Is there any connection with the unwanted emoticon arising from a right bracket?

Somewhat apropos:

I wish more posters adopted your practice of giving the link in full so that readers have more chance of knowing the contents of the bag they are being invited to put their heads into.

Why is your title mangled by the side list but not in the post itself and will this be fixed by the new software?

Steel lamp posts - sometimes see them at the scrap yard. I found a bit of 8" some years ago for a log stove chimney

Or a condemned air compressor tank?

JasonB:

Many thanks for your response.

Incidentally, the Weldon holder obviously works in practice but seems inferior in principle to the contracting collet. The Rotabroach system uses two flats at 90 degrees to each other which again seems preferable to the Weldon.

Happy to help but I will need your email address (via PM, of course).

Do you find that you can safely grip the Weldon cutters in a conventional collet?

My dad was on HMS Victorious as it was transiting the Suez Canal on its way to the Med. from Aden as the forces were assembling on either side of the canal. As you can imagine an aircraft carrier in the Suez Canal was a sitting duck if things kicked off. The Captain took it seriously enough to order the ship's crew to all write their wills.

...

I think I am right in saying that those wills would have been "privileged" in the sense that the normal formalities of execution/witnessing would not have applied.

The question then arises, who is a "sailor" for this purpose and to the headline "typist held a sailor on board ship"!

Excellent coverage the other side of the most painful tracker wall I have yet to encounter.

Thanks for the link.

As an amateur manual machinist, I couldn't follow the precise nature of every collision catastrophe but I often found myself wondering whether these wonderful modern machines incorporate clutches or other fail-safe provision.

The last excessive overhang incident showed that a simple under-support is just not good enough.

Useful tip: drop a bit of plasticene into the hole before running the tap in; the dirt, etc will be forced into the flutes and come out with the tap.

Yes, and my catalogue has:

961B As 961, but with vernier sleeve graduated to read to 0.0001"

The serial number, normally stamped somewhere on bed, would help.

My M&W catalogue is from 1970 and so no direct help. At that time "961" was the initial element in the part numbers of a range of micrometers with varying features eg "961MF" micrometer with friction thimble.

Is there any information on the reverse of the device?

I think it must date back before WWII when he joined the family company - is there any easy way of finding out when it was manufactured ?

The first step would be to ascertain the M&W reference number and then to track down catalogues for possible relevant periods. (I assume there is no date on the instrument itself, of course).

Has the use of a magnet to test for temperature been mentioned? This avoids the uncertainty of cherries, etc.

Tubal Cain's little book has excellent photos of the various temperatures and it just happens to be number one in the series.
