Gentlemen,

For information and for those living North of York, Smith and Allan in Darlington sell soluble cutting oil in 5 litre containers, or larger, over the counter; they may also have the neat version as they are oil blenders.

I have no connection with them other than satisfaction with their products

Some years ago I used to work in a great barn of a workshop where the only heating was from 2 big red diesel fired space heaters [20Kw each perhaps]. The condensation was not good; we had to thaw the coolant tanks on the DSG lathe and big vertical mill BEFORE we were allowed to enjoy some of the direct blast to do any work!!

I wouldn't recommend them, but the comment by Clive Hartland about redistributing heat from upper levels is very relevant, sadly it was not something employed in that shed.

In my own shop, a well insulated building of single garage size inside an outer barn type structure, I use a 0.85Kw capacity storage heater run off Economy 7 night rate electricity, backed up by a small dehumidifier. Sauna it is not, but it does dispell any condensation and maintains ~12 Centigrade on most winter days. It is a lot better than the alternative of heating on demand by fan heater as well as being more cost effective.

I hope that is useful info

Thank you Jason, nice to know that

Maybe you can't access your messages for some reason. I have the full set of original Haining articles in ME and can help you.

Please send me a message instead.

As usual the thread is drifting away from the original enquiry! It seems to be inevitable.

However, I do agree with John S and his disenchantment with the Myford metric banjo, shared by others as well as Derek Brown with his neat concept of a permanently installed additional metric gear train.

Graham Meek's inspired clutch, well discussed further back in these threads, now gives us the chance to draw together both these good modifications to reinforce each other and make a unified whole.

I for one am grateful to be able at last to realize a dream, long thwarted, of a full auto clutch that was so well described by Martin Cleeve for the old ML4. Making it work, selectively, for both threading languages as well will be a real bonus whilst still retaining fine feed finishing at the same time; ideal. That sort of refinement is usually in the realms of expensive toolroom machinery.

John S is quite right of course, I should have checked that before sounding off!

In my case the gearcase is further crowded by the DAG Brown metric banjo and I doubt I could even accomodate a 35 gear in that position.

My apologies to all, one of the troubles with doing calculations alone

Hello Norman

There are possibilities using the standard fine feed in conjunction with the standard Myford box. I haven't tabulated them as a Excel file, but you might find these useful

Mandrel 24--Gearbox 10TPI--12BA; Box 16--17BA; Box19TPI--18BA

Mandrel 25--Gearbox 9.5--11BA; Box 12--13BA; Box 13--14BA; Box 14--15BA; Box 16--16BA

Mandrel 25-- Gearbox 12--10BA

Mandrel 40--Gearbox 8--5BA; Box 9--6BA; Box 10--7BA; Box--7BA; Box11--8BA; Box12-- M2, M2.5

Mandrel 50-- Gearbox 9--4BA; Box12--M3

Mandrel 55--Gearbox 9--3BA

Mandrel 60-- Gearbox 9--M5;

Mandrel 65--Gearbox 9.5--2BA; Box 11--M4; Box20--M4

Mandrel 70--Gearbox 8--M6, M7, 0BA

There are many other conbinations in between the standard Myford gearset, but these are readily available with the usual provision

I hope they are useful

A tool auction box with a decent internally threaded Myford 5 inch 4 jaw chuck, a new vertical swivelling slide, still in it's grease, a small Coventry die head with some dies, a nice through hardened 4 inch Vee block and a very tired 4MT Brown and Sharp running centre [since remodelled into a Myford nosed tailstock chuck mounting] and a few other bits and pieces. Hammer price £21

Didn't I do well?!

Try Jenny Blackwell at JB Cutting Tools, they specialise in inserts and may well have a match. They are a nice friendly bunch too and are keen to help

No website or email I'm afraid

Hello Stuart,

If you are thinking of visiting North Yorkshire I would happily skim it for you, I live near Thirsk. I imagine though you would prefer somewhere nearer to you, but the offer stands.

Best wishes Brian

Tracy Tools sell ACME form taps and dies, could save you a lot of work

Brian

The ML7R does have a pin as KWIL describes, use that instead of back gear, it is much more positive ion use.

Hello Peter,

I've only just found your query, I tend to run a little behind other people with these posts.

Handbooks are available; get in touch with Tony Griffiths at www.lathes.co.uk his email address is

[email protected] I've found him very helpful in the past

I think you will be able to sort yourself out with the drawings that are part of the manual

Kind regards

Brian Wood

Hello Alex,

I tend to run a bit behind the herd with these posts and have just come across your question. Can you post another picture please with the capacitor moved clear of the other wiring, the capacitor is the white cylindrical object in the terminal box.

I can't decide whether your motor is capacity start, induction run, or capacity start, capacity run. Seenig the lay up of the other cables will help so that their tags can be read, presently obscured by the capacitor. It should just lift out.

Also, look inside the lid of the terminal box, there may even be a wiring diagram there.

Best wishes Brian Wood

I think that is very heartening; one man believed the story and was prepared to prove it. What a result.

I am just old enough to be able to remember Spitfires in battle, but strangely I have no recollectionds. It might be because my parents moved out of London in 1941 to a safer location.

Hello Allen,

Myford lathes come with a 2 Morse taper [MT]spindle socket, so all 2MT taoer shanked tooling with fit directly.

The ER collet holder probably has a 2MT shank on it with a thread into the small end of the taper which is where the draw bar screws into to pull it into tight contact in the spindle socket. It is needed to stop the whole assembly 'walking' out of the socket in use.

ALL sizes of ER socket are intended to grip parallel sided material; if your fly cutter is so equipped you can grip it either in a chuck or the ER chuck with the right size socket.

You can't grip Morse taper tooling in ER sockets

Does this help you?

Regards

Hello Martin,

If you have a 70 tooth gear wheel, it might be worth using that as the 'Mandrel' gear driving the quadrant gearing set up for FINE pitch and the gearbox at 8TPI.

I did some calculatiuons on threading possibilities some time ago, mainly to see what one could get with the finer BA thread cutting, using the fine pitch arrangement to achieve the necessary reduction in gearing. I do suggest you check it out with some M6 threading [1mm pitch] in the chuck to be sure it follows before cutting your faceplate, and remember to keep the clasp nuts engaged until the thread is finished.

Good luck

Brian Wood
