Thread: Can anyone identify this collet holder?
14/11/2015 17:10:51

Ignatz Fellinato:

A beautiful tool but unlike any ER holder I have seen (I am no expert and generally make my own).

In the absence of a public profile I have no idea where you are but there may be someone who will lend you an ER16 collet. Failing that, the cheap ones are very cheap to buy (!) and if bought on amazon, for example, can be sent back if unsuitable.

ER collet caps have a distinctive flange for extracting the collet after use which I don't see on yours.

Thread: Looking for a book from the 40s/50s
14/11/2015 16:59:58

james Schutte:

Your post rang a bell with me because I had this book as a child, lost my copy and much later was able to pick one up for 50p. My copy is stated to be an "ENTIRELY NEW EDITION" but it does contain the slot machine and X-ray camera. No publication date that I can see but produced to the prevailing economy standards.

Good luck in your search.

Thread: What direction should this forum be taking?

Michael Gilligan:

Yes, puns before pedantry any day. But can you please share the secret of inserting special characters like that e acute?

Peter G. Shaw:

Good luck with the search function. A search on "Teletubbies" just came up with nothing!

Michael Gilligan:

Isn't that "point of order" a point of information?

Where's that nice Mr Bercow when you need him?

Neil Wyatt:

I wonder if it would help if thread starters tried to make their titles as informative as possible so that those who are definitely not interested in the main topic can readily choose to ignore them.

I am not going to give examples as I have no wish to appear to criticise individual members but there have been some very vague and unhelpful titles (and some models of clarity).

G.E.O. Thomas wrote a beaut article on boring bars many years ago in M.E. Maybe somewhere it is archived?

It's reprinted in the Model Engineers Workshop Manual

Indeed, and I recall urging the OP to invest in a copy some time ago.

Thread: micrometer restoration

Paul Davies:

Yes, that looks like the catalogue item:

Paul Davies 8:

My M&W cat lists the 940MX with locknut, rather than clamp, and alternative anvil to give greater range. Is this your type?

13/11/2015 11:12:10

Paul Davies 8:

I suppose that mic can only have seized through rust or oxidisation, etc of the oil on the screw. Rust would be bad news, of course. The next question once the mechanism is free is what lubricant to use to protect the mechanism in future?

I have never heard of a mic seizing before. Are you sure the clamp isn't on?

Thread: New lathe arrived today : The ongoing saga
13/11/2015 11:02:46

Brian John:

I always use this kind of boring bar - ie round section with flats top and bottom - in a shop-made holder either of the kind described by GHT or a simple split block closed by the tool post clamp screws.

My understanding is that they are made so that the insert is on centre when the flat is horizontal and the bar centre level with the lathe centre line. This means that you can make an accurate holder by gripping the blank in the toolpost and drilling, boring and reaming with tools held in the lathe spindle. I am not sure how this would be done in detail on your lathe but believe the principle is sound.

Incidentally, using the same approach you could probably make a holder for the considerably stiffer 8mm bar.

Thread: help needed in exeter
12/11/2015 16:55:39

Ady1:

I agree and think it would be helpful if the "county/state" box were a required field (it would still be possible for members to decline having a public profile).

Thank you for indirectly answering a question I asked elsewhere on the forum.

Thread: M1.7 - what is the history behind it?
12/11/2015 16:41:17

John W 1:

"There is a site that lists metric threads that might be of interest."

Thanks for reminding me of this useful site - it feels odd that one goes to the US for such a comprehensive list.

Thread: The Interesting Dynamic Properties of Blu Tack
10/11/2015 23:05:24

Michael Gilligan and Mike:

Thanks for the link and for the information which I will follow up. It sounds as though Sorbothane might also make a good base for the bench grinder.

10/11/2015 16:39:30

Michael Gilligan's interesting piece (No 235, p 61) reminded me that my cheap and cheerful Astra bench drill has been sitting on four Blu Tack pads for many years. I have yet to borrow these and try his experiment but, provisionally, understand that in that position the material will be stiff until re-kneaded. In my innocence, I thought it would retain its damping qualities as well as locating the machine.

Is there a better material for my purpose, I wonder?

Neil Wyatt:

Thank you for this and no doubt it was the route by which I set up my own profile but how does one choose what information is public?

Other forums encourage members to give an indication of their location presumably because it opens up the possibility of direct contact as, for example, in the Optimum saga.

Thread: A new small lathe on ebay from China.
09/11/2015 18:08:34

"The base looks like it might be a piece of steel rail from a railway track."

I have seen this very thing done and remember a knowledgeable friend explaining why it is not the best way to provide a very stiff foundation for a lathe bed.

I think one of the pictures in the listing illustrates turning nuts!

Thread: Belt splicing tape
09/11/2015 17:59:34

Brian Wood:

Perhaps I should have been more specific! I permed Trevorh's "high impact cross weave tape" with your reference to amazon, searched on amazon and came up with the negative result I quoted in my post. A google search does indeed throw up items on amazon and they do look like the tape I have seen on commercial abrasive bands.

What I was after was a more positive indication of a particular product which will do the job.

As to your question, I don't think I had a view as to whether you had searched or not.
