Thread: electrical fault puzzle

Where there's a rural ceiling cavity there's always a chance of mice.. ..the dribbly little blighters..

Thread: clarke CL430 lathe

Isn't there a dial on the handwheel - how's it marked?

Thread: Play in new arbour for mill
16/09/2023 19:06:30

What size and fitting is it?

..that sounds rather a lot of money for a drill chuck arbor..?

Thread: Kerry Lathe Tool Post
14/09/2023 17:06:18

(Well look at that, after three years or something, I've found my original login)..

Looks like the Kerry might use a T-slotted topslide, if that's the case a wedge- or piston- type 'Aloris' (or clone) should be a fairly straightforward 'slide-in' unless the Kerry uses some obscure 'nut' size - these toolposts mostly come with a stud and large flat T nut as standard, originally intended to replace the lantern-style toolposts that were then still common in the US..

I'm sure you'll find dims. somewhere on the 'net.

The wedge-type is a good toolpost, solid and repeatable in use, with cheap to buy / easy to make holders..

Piddock!

Thread: Lathe improvements?
03/10/2019 08:36:02

..that is cheap, BUT..

..yours is built with personally-selected components that have been hand-fitted to meet your own specifications for performance, durability, and accuracy that you know to be absolutely true, because you made it yourself.. ..you can't buy that for $700..

Thread: Perfecto 3-1/2" x 16" lathe half nut lever operation
03/10/2019 07:41:06

Hi Charles, looking good.

Whilst it is apart, it might be worth checking for burrs along the edges of the pin slots, particularly the curved ones in the disc. As well as any obvious ones caused by damage, also check with a finger for any feeling of sharpness inside the track edges (overtightening of the disc in the past can sometimes cause burrs here).

In the ML (albeit the tracks are a slightly different shape), burrs along the lip of the track can give a rough action or even cause sticking, and it could be this which has caused someone to be rather rough with yours.

If any are present, lightly dressing them back with a small file gives a noticeably smoother action.

Happy to see it progressing,

Thread: nutcracker
01/10/2019 11:27:47

pgk - seriously, for hedgerow nutting, I have great success with a middle-sized (9"-10" pair of water-pump pliers - whilst slightly too big for the back pocket, they do fit comfortably in a waxed cotton jacket, have a cut-out in the jaws, and the long handles give such control that the shell can be cracked without crushing the kernel, particularly once one gets a feel for the adjustment. I've never looked back!

Thread: Perfecto 3-1/2" x 16" lathe half nut lever operation
30/09/2019 08:02:51

Just to reassure; because the half-nuts are balanced, i.e. the upper one is held up by the lower, if you will, the only out of balance part that gravity would have to overcome would be the weight of the small operating handle - friction in the gib alone is sufficient to overcome this, whilst still providing light operation..

30/09/2019 07:55:31

I have just been out to check my memory of the ML4 apron in my slippers, and the omens are all good; the action is virtually identical - the handle is held in the up (disengaged) position by friction alone, derived from judicious adjustment of the gib.

Whilst I can't guarantee that mine hasn't been mutilated in some subtle way over the years, there are no detents of any kind, or evidence of there ever having been so, and it used to operate quite satisfactorily. The gibs are not over tight - the operation is light, but there is enough friction to hold the lever in the "up" position - perhaps because the dovetail contact area is quite generously proportioned, as I see is yours.

I'd use grease (rather than oil) as a lubricant during re-assembly, and carry out a final adjustment once it's all back together and hanging in it's proper place on the saddle.

If you'll pardon the question, what are your half-nuts made of? ..perhaps it's a trick of the light, but I'd hope it was some kind of bronze..

Good luck with the restoration.

Thread: Unusual GPO hammer?
29/09/2019 10:03:38

The "curved pointy bit" looks very like the shape a tinsmith would use to persuade sheet-metal over a wire in order to create a rolled edge..

Thread: Electronic water gauge
24/09/2019 11:05:27

..looks like there's a schematic on page 2 of that thread..

24/09/2019 10:51:32

There's a thread on the "Paddleducks" forum, titled "Water level sensor", in which reference is made to Stan Bray's book "Model Marine Steam".. it's here.. ..some way down..

www.paddleducks.co.uk/smf/index.php?topic=6138.0

I searched "electronic water level sender model steam", so something along these lines might throw up more results..

Thread: Manual for a Meddings M10 High Speed Drill
24/09/2019 09:54:39

Have you tried Meddings themselves?

Thread: Stuck oil filter
22/09/2019 13:00:30

Search "Oil Filter Cup Wrench" - which is just a large "proper" socket, designed to fit over the Hex that is on the end of the filter. Saves a ton of messing around, especially in a restricted space..

Thread: Miitutoyo caliper error
22/09/2019 08:53:41

I have paper instructions here.. .."E" does indeed mean the scale needs cleaning - the instruction say to clean the scale, and if the "E" error message still remains, it is necessary to then remove and re-install the battery.

If still no go, I would try disassembly and cleaning the inside "track reading" area of the head unit before I consigned it to the scrap bin..

Hope this helps

Thread: Fiducial lines on a Zeiss Microscope Eyepiece
20/09/2019 07:35:53

..but of course you wouldn't see it through an eyepiece.blush

20/09/2019 07:32:30

Apologies if this turns out to be a stupid comment, I know very little about microscopy - but don't camera lenses employ an alternative fiducial line for focussing in the infra-red part of the spectrum?..

Thread: Any interesting lathe projects for beginners?
18/09/2019 08:01:26

File - I agree entirely with Nick W. ..it's worth the investment of learning for at least two reasons I can think of (before 8:00 in the morning), although I do stand to be corrected, of course

1. Filing small and/or awkward components can often be completed in the time it takes to set up a milling operation - finishing curves, for example..

2. It doesn't take very much practise, and only a (relatively) small investment in the correct tools, to be capable of producing a very high standard of finish.

It does take a little patience!

17/09/2019 08:22:20

Do you have other machinery?

A very common source of small workshop projects - for example, any covers, controls, or adjustments that require a spanner or key to operate might benefit from a dedicated, well thought-out handle, perhaps to make speed changes less of a chore.. Do all parts (depth stops, table- and mitre-clamps operate accurately, smoothly, and as you would wish them to?

Fixes can be as simple as say, making a thicker chamfered washer to move the stop position of a clamp handle to prevent it fouling other parts, to as complex as one might ever wish.

With regard to your comments about steam engines, try a Stirling - if you pick the right "wrong" design the resulting expenditure of time and effort for so little gain might well cure you of latent-but-unwanted engine-building desires for ever smiley
