Fascinating stuff! For some reason it reminds me that Gamages had an establishment there, too.

Liam Hutson:

I think that this sort of upgrade is usually a shop-made effort calling for some straight forward turning and dividing. GHT's MEs Workshop Manual may give you some ideas about how to go about it. You would need to identify the leadscrew pitch of course and decide whether to go for radial or diametral marking ie whether a given depth of cut is off the radius or diameter of the work. From your photos it looks as though one problem would be the location of a witness mark.

I see from the link to Tony's website that on some of these lathes "cross and top slide were fitted with, for the time, generously dimensioned micrometer dials" and it would be helpful to know how the manufacturers approached the problem. He can be very helpful but does say that his email load is very heavy.

I can't suggest a specific source of an existing item and, apart from the cost of such things bought as spares, there might be some reluctance to sell them for use on a "foreigner".

JasonB:

Thanks - although it looks as though they "went bust" some time ago.

I think my own modest set of BMKs was bought about the same time ago; rather like spindle hole size one never has enough!

The apparent absence of micrometer dials on the slides is a clue to its age but you might well want to fit some.

JasonB:

I looked at your finger joint link and see that you are using the excellent BMK cramps. I have tried without success to source these from time to time and wonder where you got yours.

Thanks for the link.

I liked the comment that "the battle between vees and flats has given rise to much fruitless controversy".

I trust and pray the dam won't burst but, if it were to, would that be an "Act of God"?

When I saw the news I wondered whether the dam had been constructed correctly.

FullaFlava:

Thanks for the tip. I see you have the highly-rated MultiFix type toolpost. Brass chips will get everywhere and I wondered whether you have to take time to clean down the mating components when changing tools?

BTW, this and other recent posted pics highlight the need for advice from some knowledgeable member about rotation.

Or worse. I once attempted to drain a flooded single story flat roof with a garden hose by this method and the rush of water to the back of my mouth had me (standing on the ground) fighting for breath.

Thanks for the further enlightenment.

My only experience of this sort of thing was when a friend produced some large artworks in steel and roped me in to help him erect them. I don't remember the process - they might have been flame rather than laser-cut - but I do recall acquiring some of the circular offcuts.

I'm sorry to see that Michael Gilligan's light-hearted response to my post was seen as an excuse for this. Howard Lewis got it right: "It's not WHAT you use for transport, it's the way that you BEHAVE with it that counts."

I understood the programme presenter's theme to be the factors leading to the advent of the motor car. Here's a link to the historical point I had in mind:

Martin Rock-Evans:

Thanks for the link. He seems to stock only the 1L size, however; when I need to I shall be looking for the more economical 10L

At last, another PR88 user.

An excellent product but not readily available. I see you are in Devon and wonder where you get yours.

Paul Lousick:

Thank you for the explanation.

I suppose I had in mind that it might be possible (if not economic) to run the laser using some suitable cheap material to produce a result which could be checked by the customer; all being well, the real job could then proceed.

Is there some way a laser cutter can do a dummy run to check?

He covered essential elements like the wheel, axle and roads but did not mention that the development of the last was driven by the cycling boom of the late 19/early 20C.

Intriguing that the inspiration for Henry Ford's assembly line was the abattoir.

Michael Gilligan:

Thanks for the interesting Sumitomo link - I had no idea they were into this kind of thing although they know a thing or two about steel.

J Dewar McLintock professed to be "hooked" on the Dauphine and has a good deal to say about it in his book about Renault including the gift of one to the Queen which was used by her and the Duke (!) at Balmoral.

Copper or aluminium?

By way of complementing the points made above, I seem to recall that the Renault Dauphine's battery lived in the (front) boot and that the relatively long cable run was in aluminium.

Not sure how much fair play was involved in the Eton Wall Game!

The American author of Spindles (WPS 27) clearly had a high opinion of the S7B. Interestingly, however, he says:

"Most of the work I carried out was done on a Myford Super 7 ... I did use a 10" South Bend lathe to do the heavy work when a lot of material had to be removed. However, all this work could have been done on the Myford ..."

The Americans are rightly proud of their machine tool industry but I think this has tended to blind some of them to the merits of the Far Eastern product.
