Try this, looks like a private UK seller...

Cambridge won 13 races on the trot 1924 to 1936..?

Thread: Workshop and Drilling holes with an ER collet chuck
02/05/2021 08:49:51

..And.. ..a bit of cross-referencing and canny selection can let one hold certain metric 'part-sizes' in imperial collets (& vice versa) without needing to squash them down to the limit, if they're going to be used frequently..

Why is your chuck so tight - might be worth checking that there isn't a burr or 'ding' on the keyway / key? - if it's been in-and-out a couple of times you might be able to see where it's been rubbing..

Thread: Problem with a dremel
01/05/2021 17:18:00

Hm, maybe. ..I'd (unplug!) and check the brushes first, they are under the little caps on the sides opposite the speed switch - the original brushes aren't very generous..

If the brushes are okay, whilst they are out, peer down the little hole and see whether there's debris stuck between the segments of the commutator which is probably the most likley place for trouble of the kind you describe.

If you can see debris in the commutator slots, use a cocktail stick or a splint of wood to fiddle it out of the brush hole, or dislodge and shake it out of the back cooling slots.

If you need to 'split' it, the screws are some squitty Torx size (sorry, they're not in mine anymore - could be T2.5?), it's straightforward inside, note how the cable is routed between the pillars ('cos you'll have to get it back exactly the the same way if it falls out).. ..the motor is supported (I think) in a rubber bush at the end, and might have a 'hole and pin' register to stop the bearing spinning that has to be lined up on reassembly.

The bearings are supported by the plastic casings which aren't very accurately moulded, I had to fiddle around with the screw tension (to the point of tiresomeness) once I'd reassembled mine in order to get it to run smoothly at high speed..

Will it work on cast iron ? Noel

I wondered the same thing..?

For steel, I'm not too keen on used engine oil, I find that organic (vegetable) oils give a noticeably 'blacker' and more even finish - linseed gives very good results..

Thread: How Do I Open Walker-Midgeley Documents Please?
30/04/2021 07:26:30

Firefox (the standard browser) will open .pdfs - right click the document and go to 'Open with' in the drop-down and Firefox should be there, I think MSEdge will also open .pdfs..

If you know how to set defaults, then Firefox (or Edge?) can be set to open .pdfs just by clicking..

If neither of these are available, or one can just (still?) download the free version of Acrobat Reader from good ol' Adobe themselves..

UK made and cheap..

JB Tools

Thread: First steps with a Shapeoko router table

It's a pretty substantial-looking piece of machinery, I watch with interest.. ..and maybe a little envy - looks like fun..

Thread: CNC Lathe Scratch Build

Joe, if it is any help in any way (and you haven't been there already) there are some useful downloads on high speed spindle /contact-free seals here, including labyrinth sections, photos, detail of design aspects:

Thread: Hobbymat MD65
14/04/2021 06:54:09

I might try cleaning up the bore with a piece of hard wood / 'coarse rag on a stick & vinegar' or similar before resorting to the reamer - the spindles and shafts are of very soft steel on the Hobbymat. If you do need to ream, go very lightly, just the tiniest skim. The size is 1MT.

Thread: Face Knurling...
11/04/2021 18:50:58

Just musing out loud, but might there be a way of 'cut-knurling' these.. ..driving the shallow-angled corner of a wheel across the face.. ..can't remember whether I've seen it done or not..

..only posting in the hope it might jog someone else's memory..

Thread: Loctite or Draper? Much difference?
11/04/2021 18:28:11

542 is a high spec. hydraulic / pneumatic pipe sealant, if you just need a 'general purpose' thread lock and sealant for machinery assembly, use 243 which is (much) cheaper.

If you need it for HP pipework in an extreme environment then you can check the suitability of equivalents from the manufacturer's datasheet.

If you do just need it for general assembly, then as Clive says, any similar medium strength ('blue' ) lock'n'seal type products ought to do the job.

Thread: Three Cylinder Steam Aero Engine
11/04/2021 10:45:04

Nice job, John - the inlet pipework looks much more in proportion to the whole. ..I rather like it without paint, too - tho' it always feels a bit cheeky to be commenting on the finish of another's engine..

Please keep us updated on the prop and other bits & pieces, it's an enjoyable build...

Thread: MS 'Edge' - Points and Pitfalls?

I hope this fits in with this thread. It may influence the decision of the OP before he changes supplier.

I have continuous problems with Chrome and Google. I get the dreaded "Before you continue to Google Search" popup each time I use search or change sites no matter how often I go through the settings

I have tried various fixes from groups on the net. The last one worked for a while but I suspect that the latest update has found a way around the fixes.

From online comments I see I am not alone with this harassing behaviour.

Are the other browsers like Edge Brave etc, any less intrusive in your experience?

Has anyone a fix that works, short of giving up?


Some of your problems may be linked to your cookie settings - if you have your browser set to 'delete all cookies on exit' or some similar setting, then every time you exit and re-enter sites you will see all the reminders, warnings, and acknowledgement tick-boxes anew.

It's probably possible to enable cookies for selected (frequently visited?) sites in your browser settings.

It will undoubtedly become harder to 'escape' having to accept unwanted cookies because they are increasingly a resource worth large sums of money.

Because some providers would very much like you to retain all their cookies, there comes a conflict of interest in making sites easy to access for those who don't wish to cooperate or participate in their marketing programmes.

FWIW Firefox is a lot less 'nosy' and with better privacy settings than some of it's competitiors..

Nigel, for e-mail, one can use Thunderbird - it's free and from the same developers (Mozilla) as Firefox...

I use both, very happy with them.

Thread: Shaping Skew Gears on a Lathe
07/04/2021 12:16:16

A take on manufacturing skew gears that I'd not seen before, not a tutorial by any means, but with enough detail on the home-built set-up to be of interest to others, maybe;

Looks very much the same as the charging lead on my Karcher window vac, but of course that's only low voltage. Is there any chance a standard figure of 8 lead would fit? I think they are called C7.



Not as it stands, Phil ... The vee is quite pronounced

Thanks for the thought though.


..if only we had a milling machine..

Inspirational and beautiful work William, I am in awe. Thank you for posting this and please keep them coming, this is just the sort of thing I love to see on the forum.


..Exactly my sentiments.. Thanks for posting Williiam

Thread: Is RSJ Steel machinable?

They'd make the basis for a useful hydraulic press if you add a cheap bottle-jack and a couple of bits of angle..
