|Thread: Taper attachment capabilities ?|
Hello Siddley, Keith and Alan
I thought I had some pics, but they are rather poor, so I will do another more complete set and put an album together,
In the meantime KWIL has shown a nice version of the same sort of thing. Mine is of course full length as I've said.
I chose hydraulic ram material from the experience gained in making hydraulic forming tools at an agricutural engineers works, the seamless honed tubing having beautifully finished bores comes in all diameters and is another joy to work with. I was especially keen to eliminate corrosion damage and just observing modern excavating machinery with polished rams working in all weathers convinced me in my choice
So patience please, all will be revealed soon!
I made a full length taper turning attachment for my Myford S7 variant using a 20 inch length of 18mm hydraulic ram as a guide. It is hard chrome plated, straight as a die and resistant to bending as well as being on size to within a gnat's whatsit. The bar is carried on two cantilever supports built out from the two ends of the bed; the tailstock end has both fine and coarse adjustments to set the angles. The headstock end is just in steps of 50mm, so by juggling about you can cater for tapers that close up or open out with tool travel towards the headstock. Setting in my case uses the DRO to define the angle over a set length.
The slider is a hefty section of aluminium bar bored out to be with a close fit on the guide bar and is closed at the two ends with felt wipers to keep the grot out. The vertical link up to the cross-slide is a sturdy 40mm diameter chunk of bar to resist any side motion flexing.
In use you disconnect the cross-slide feed screw and let all the motion come from the guide bar. Angles of +/- 10 degrees are about all you can expect before it gets cranky and moves in jerks.Tool feed is put on by the topslide. My installation is permanent, it is far too fiddly to be putting it on and taking it off and I've cut good Morse tapers with it.
In my opinion it has the advantage of quick access and the ability to cut a really long taper that the proper Myford accessory can't do, being limited in length. That is a brief description, I have no drawings since it evolved as it grew, but it should be enough to impart the essential elements..
The vital guide material can be bought as a cut length from hydraulic engineers who offer a repair and overhaul service. I think mine was about £1 an inch at the time [~7years ago] Look them up in Yellow pages.

|Thread: Source of "Soft" Iron?|
I have a transformer lamination to which you are welcome. Overall dims. are 170mm long by 39mm wide, with two punched out slots leaving a 95mm undamaged section between them at 39mm wide. Thickness is 0.80mm. It is a little rusty here and there, but it is not heavy damage.
Transformer laminations are ideal for your needs requiring the rapid build up and collapse of magnetic fields where any residual magnetism would severely limit magnetic field strength and nullify the operation. If you PM me with your address I'll post it.
|Thread: advice re scroll saw|
Hello again Ian,
Just a thought while I was cleaning my teeth! For the use mine has had since I bought it, virually nil really, I would be happy to sell it on if you are interested. i think I have some blades for it, a book of projects and I will still have the owners manual hidden away.
If you are interested send me a PM. I live just outside Thirsk North Yorkshire, it is not the sort of gear I would trust in the post.
Kind regards Brian
I bought one some years ago from a joiner who was selling up after diagnosis with emphasima [sp?] and in pretty bad shape. It is a Woodwise PM22 dating from 1992, maybe no longer trading,
It has a cast iron base, table and operating arms, it is heavy and sturdy. The whole thing stands on resilient feet and it handles as a solid quality machine. It looks very much like a Hegner and capable of delicate work as well.
To be honest I haven't used it a lot so I can't give you much operating experience but that is the sort of thing I would look out for.
Enjoy your pressie Brian
|Thread: Cutting oil|
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
|Thread: workshop heating|
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
|Thread: Old Issues|
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.
I've sent you a PM
|Thread: Myford Gearbox and Metric/BA|
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
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
|Thread: What was your best buy|
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?!
|Thread: Parting tool Inserts|
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

|Thread: Machining services|
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
|Thread: Which MEW had acme thread and tap article?|
Tracy Tools sell ACME form taps and dies, could save you a lot of work
|Thread: Myford chuck security|
The ML7R does have a pin as KWIL describes, use that instead of back gear, it is much more positive ion use.
|Thread: Tom Senior Milling machine (Junior)|
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@example.com 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
|Thread: Wiring new lathe motor|
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
