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.

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...

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..

Thread: Milling Attachment for Flexispeed
14/03/2021 20:54:55

Looks like a good idea turned into an effective attachment - nice work. .you could make a drilled & tapped plate to bolt to the top of the slide to clamp work to, if you are stuck for a vise?

According to this is 240mm dia sure enough..

..I'd never cut someone else's property up of course, but the bigger ones are only about a skinny 3mm, sorry can't be more specific - I'd hazard a guess that the 4.5kg will be about the same thickness.. could 'double-layer', I guess...

It is - this chap (to whom I have no connection) posted a record of removal / replacement for posterity here;

Bazmonaut MD65 Spindle Bearing Replacement

Thread: tapered roller bearings
13/03/2021 10:03:02
Posted by Henry Rancourt on 13/03/2021 01:09:53:

Since I have to replace the bearings I think angular contact bearings with tighter tolerances make sense. They don't cost much more than top quality tapered roller bearings....

Do bear in mind that the original taper-roller fitment might have been deliberately chosen in order to meet some specific requirement - controlling whip in the end-driven spindle, as an example...

Henry, just out of interest, what is it that you find unsatisfactory with the standard set-up?

That's looking really good, Ron, nice work an' a useful read as well..

Thread: Shimming Techniques
03/03/2021 08:04:53

There was no play in these bearings that could be felt by hand - before & after adjustment, using same cutter & set-up..

It'd be perfectly normal to have to adjust the spindle bearings after a period of running as the cycles of heating / cooling, vibration and pressure settles the components into place against each other, and the initial cold setting made at the factory is lost..

Maybe someone (with knowledge of the SX?) could explain the 'how to'? ..I'm gonna be really late for worksurprise

..If you centre the spindle over the fixed jaw of your vise / edge of a parallel /slot/angle plate first, you will have a diametral reference plane against which you can then visually check the set up of the cutter...
