Thread: Recommended Lathe speed?
09/04/2020 17:51:35

Another point in favour of a suitable speed less than maximum is that, as you know, brass chips go everywhere and I think this will be less of a problem at the lower speed (don't know if a chip shield can be used with your Turnado).

I remember hearing that thorns could be used in lieu of needles; can anyone confirm?

We still had some in about 1960, and a device for sharpening them. Dad said that they were made of hawthorn, though whether it was the actual thorn or turned from the wood of the stem I have no idea.

George B.


Very likely to be the actual thorn, I would say: We have Hawthorn trees in the field behind the house, and some of the thorns are impressive to say the least [and they do make very good material for crafting miniature items]

I suspect [but have yet to find any proof] that thorns were harvested, and used for their special properties.



Edit: I have just looked at the [His Master's Voice] packet, and I see that the needles are described as thorn

Not Thorn EMI, then!

Thanks for your reply above re the tip; I speculated that the shape might be a response to the difference between the inside and outside of the recording groove.

This is a stereo pair [Stereoscopic, not Stereophonic] angel

The tip of a commercially manufactured wooden ‘gramophone needle’

... i.e. not a natural thorn

I wonder what is the "point" of the asymmetrical tip?

Did the needle have to be installed in a particular axial orientation?

An onomatopoeic recording about steam locomotives - diddly dee, diddly dee, etc - I don't recall the name.

MC wrote a number of articles about improvements to the EW. His steady design was updated some years ago and written up in one of the magazines. Here is my version of the latter:


You do need a bush for each size, of course, but the advantage is that in theory at least they need no axial adjustment.

My traveling steady has been used but think a Martin Cleeve bearing-type steady would be better for much of my work.

One use for the MC bush-type steady would be to get round the problem of the small Myford spindle hole.

Were you thinking of a travelling version of this? Not sure how this would work for repeat cuts.

Yes, that RTP looks like an early Myford job with its boat-shaped tool height adjuster.

One small mystery I can solve is the disconnect between the text on MEW 292 pages 67 and 68: on close examination, the first line on 68 has been near-obliterated by the red line under the pull quote at top left, which has been repeated on page 70.

Read my article in MEW issue 292 about adjustable chucks, more will be said in the following issue about the tightening screws.

I'm looking forward to the solution to this "great mystery"!

I'd be grateful if anyone who does buy the latest edition could let us all know whether its 2996 pages are section-sewn or merely "perfect-bound".

And whether the thumb index is present?

I find it helpful to insert photos using the camera icon between two carriage returns; that way you can always insert text above and below the photo.

Thread: Griptru wil not ad just

Well, I have viewed old mart's video, looked at MichaelG's link to the thread on the PM site (well worth reading in full) and re-read GHT's advice and conclude:

1. Slight loosening and final re-tightening of the retaining screws is unlikely to do any harm and may avoid straining the chuck through heavy-handed use of the adjusting screws.

2. The man in the video, who did not loosen/re-tighten, seemed to make rather slow and heavy weather of the process.

3. I have no immediate suggested answer to the OP's question beyond that already given by Tony Simons (over-tight retaining screws) unless the chuck is actually defective or damaged.

4. I need to do some experiments.

PS I haven't used this setup for some time but, looking at the photo, I can see that the "top slide" gib is on the wrong side for taper boring, something to bear in mind for the future. That said, I don't recall any problem of lack of adequate stiffness.

In default of a TTA I have fitted a spare ML7 cross slide to my S7 cross slide:


Fine adjustment of the "top slide" is via the gadget installed in the front tee slot.

Nick Clarke's ME article:


Plus correction:


PB leaflet drawing:


PB leaflet instructions:


My immediate reaction to the ME article was that my Griptru, which I think must be the Myford/Burnerd direct mount type, doesn't have the "tie-bolts C" referred to but does have three cap screws in the back of the chuck; these are the screws that I slacken slightly and then re-tighten after using the adjustment feature.

The ME correction, of course, retracts the advice to loosen screws "C".

The instructions which came with my chuck say nothing that I can see about loosening and re-tightening, a practice which I have adopted in light of GHT's advice.

It is apparent that the Griptru came in various forms.

Time to do some more experiments on the hardware!

PS I have yet to look at old mart's video.

A very timely offer as I have just been vainly trying to upload the results of my researches in PDF!

I won't trouble you unless I have to as I can probably re-scan to JPG.

Nick Clarke:

Many thanks for the offer; I will see if I have this myself but if not will certainly PM you.

I suppose it might be a public service to post the article on the forum.
