Thread: Exploding Grinding Wheel
30/06/2020 09:36:27

A previous employer of mine sent me to do my 1 day abrasive wheel course on 21st June 1979. ....despite me asking for the day off as it was my 21st birthday, I still had to attend...

Thread: Harold Hall basic grinding rest
29/06/2020 06:38:19

Thanks again for your replies.

Magnetic hold down method similar to the advanced version seems the way to go to add a bit of versatility.

Regarding the table moving as it's only relying on the plastic ball and one countersunk screw is an excellent point, I wonder if the problem exists if the ball is metal as in Danny's example.

I guess any design has areas for improvement

Thanks guys for your replies.

Great photos and really useful information . As I have an 8 inch grinder I will have to do a few mods to the height. Regarding this, is the height measured from the table to the base to coincide with the centre line of the grinder? or is near enough ok?

I am also going to fit a cup wheel instead of the normal straight wheel.

Yet another job i am going to do is to use the method by "stub mandrel" on this site to modify the way the wheels are mounted on the spindle - currently it uses a 1mm step on the shaft to ensure that an 8 inch grinding wheel runs true! Something similar was recommended by Harold in his book "Tool and cutter sharpening".

What a great forum this is, so much help and information....!

Hi everyone

I am looking at building the simple grinding rest by Harold Hall, as opposed to the more involved and longer to build advanced version.

So my question is how did the build go and how are you finding it during use?

Although the advance version looks more versatile I have looked at both designs and the simple version seems to do all that I want such as grinding lathe tools etc

Looking forward to your replies

Thread: A polite question - from a beginner :) Drilling a NONE wandering hole
21/05/2020 18:09:00

Hi at the risk of hijacking the thread, I would like to ask Jason to clarify what he thinks is a small drill that is too small for sharpening?

I have discovered in my workshop lots of small (less than 2mm) drills but despite using a micrometer on the shank (yes I know it's not accurate!.), I am not sure if they are a number, metric or imperial size!

I have always used centre drills or just drilled via a dot punch but I suppose these new fangled spotting drills are the answer to more accurate starting of the drilling process I have never used them....but of course the drill has to start in the right place whatever process you use to mark out where the hole has to go.

Regards to all.....this is a great forum!


Thread: Understanding Digital Subscriptions
12/05/2020 13:46:58

Thanks Neil that has cleared up some of the confusion I have.

I am now going to treat myself to a digital and paper subscriptionto MEW!



Thread: Reading Digital MEW
11/05/2020 20:48:29

And that's why unfortunately I wont go the digital way.....too many variables.

In this day and age why is it not all viewable via pdf......or is that too simplistic?

As I understand it mytimemedia you can see the archives but difficult to read and impossible to print a hard copy whereas pocketmags you can... but not if you use windows 7, but seems to work ok on apple stuff....

To be honest this really needs sorting doesnt it?. Most of us would sooner be "lathe-ing" than wasting hours fiddling around with a pc/laptop/tablet trying to access something that should be easy and that we have paid for.

Rant over.....sorry!

Regards to all


Thread: A Big Thank You to all Forum Members

Well said Neil and big thanks to Jason.

Welcome to all newbies who have joined.

I would also like to thank CUP Alloys, Chronos and Arc euro trade - those suppliers that advertise on this site and give us fantastic support.

I have recently placed orders with these companies and have found them all helpful and friendly. I have received my "bits and pieces" that I ordered with no problems despite the current virus related issues that are currently causing much disruption for us all.

Great job Neil in making us all welcome, well done!

Thread: Inconsistent access to MEW archive
22/04/2020 10:59:57

Hi all

I am dithering on taking up the latest offer to subscribe. One of the attractive things for me though is access to the archive, and possibly the potential to print off articles....and that in itself seems problematic.

It does appear though that there are difficulties with reading or accessing the archives, I am not very computer literate and I am reasonably confident that I would not have the skills, or the patience! to be able to resolve it. I find trying to resolve silly issues with computers a frustrating time wasting exercise to be honest. There seems to be too many variables that needs to be in place before a user can access these archives, it must be a simple way isn't there?

I am in the process of culling my old copies of ME and extracting useful information that interests me. I am not sure if I want to start collecting more hard copies (even if it is MEW!) Hence the choice of digital format plus archives is my preferred option but......

Regards to all


Thread: Metric taps and dies - and pitches
16/04/2020 14:08:17

Fantastic response guys thanks.

I have Tubal Cains book...why didn't I look in there first?......doh

Much clearer now. I guess its metric coarse by default if the instruction/drawing says to "tap M5" for example, otherwise it would be specifically stated if the metric thread pitch was to be any different ...say "metric fine (MF?)

Thanks once again everyone

Stay safe



16/04/2020 11:56:12


I am a little bit confused with the metric taps and die choices available. I have loads of "imperial/English" taps and dies and am more familiar with feet and inches to be honest from my apprenticeship days long ago. But more and more drawings are referring to metric "stuff".

Now I don't mind metric stuff - I have a metric Emco mill, and an "English" Myford!

So to my question.

If a drawing says tap or thread for M5, does it actually mean M5 x 1mm pitch or M5 x 0.8 pitch etc.....? For example Tracey Tools show that there are 5 different pitches with an M5 thread.......and I thought metric was supposed to be easier!

I am sure there is a table showing the preferred/standard metric tap sizes and pitch for Model Engineers somewhere....otherwise do I just use the Metric "Coarse" range? (it seems so much easier with the "old" stuff e.g. tap 2BA or thread 3/8" BSF for example...wink....)

Hopefully one our our resident metric thread persons on here will be able to advise which of the 5 available choices of M5 I should buy - in fact what metric taps and dies should I buy and what pitch?



Thread: Which is the most popular
31/03/2020 18:32:56

I would sooner subscribe via this official site and support ME and MEW as well as gain access to the archives.

Ian and Georgineer, I am going through the same process of rationalisation of all my volumes of ME's, was going to do this in the Summer but looks like the ideal time.

Going for print and digital for 6 months then decide.

Thanks for all the replies and comments to my post



31/03/2020 09:47:44

Thanks guys for your replies,

I think I will go for print and digital to see how it goes, and then maybe go digital only next time...I am assuming I can upgrade/downgrade my subscription package?

Thanks again!



31/03/2020 07:42:27

Hi everyone

So I am thinking of subscribing to MEW but not sure if just digital or print plus digital is the way to go.

I would like access to the archives but have loads of old ME magazines that are now just taking up space don't really want to add to them however when making something for me it's more practical to have a hard copy in the it easy to print out hard copies from digital only? I have read on here problems with on line readers and pocket mags etc, dont want extra "computer" hassle!

So just wondering what the preferred subscription option is that all of you on here use....pros and help me choose

Thanks and keep safe


Thread: Machine feet/mounts?
27/03/2020 12:56:08

I guess that the construction and manufacture of the metal outer part, rubber, threaded rod, nuts etc plus all other costs etc. Everything is more expensive than it should be ! smiley

I expect shock proof and and levelling are the features of the component

I have never understood this mantra of having to grow at "x" % every is not possible. It certainly doesn't happen in nature, trees grow to a certain height then die. Trees don't continue to grow higher and bigger, otherwise the planet will have just one big tree.

Sustainable growth should be the key...

We are all saying that this virus thing will change things.....but when its over and in a years time I suspect we will revert back to pre-virus days....

Thread: Machine feet/mounts?
27/03/2020 10:29:14

Hi guys

I have been also looking at those big yellow machine mounts for my Myford.

I have a concrete base but made the mistake of interposing a piece of kitchen worktop (compressed chipboard) between the concrete base and the Myford stand. Unfortunately the chip board has been doused with coolant and absorbed some moisture over the years and is now sagging and crumbling and not able to support the weight of the lathe.......yes I know it was a mistake!

If anyone has feedback on their experience of these mounts then please let me know. Looks like they cost about £40 to £50 for the 4. Spotted a site on ebay selling 4 for £48 free postage...they look all the same though. Looks like M10 size are the ones to go for.

Keep safe everyone, good excuse to self isolate in the workshop and catch up on all those jobs


Thread: Old model engineer magazines
12/03/2020 09:55:34

Some great ideas, thanks.

I particularly like the idea suggested by Baz!

I also agree with Martin where it does feel like throwing your life away - very sentimental attachment to some issues and volumes - odd feeling isn't it?

So I am going to decide how I am going to create the new system. Probably something like:- Workshop tools that I want to make, Workshop techniques, Stationary engine constructional articles, and articles by Duplex, Tubal Cain and George Thomas plus another couple of categories and that is it I guess. probably condense the lot into a couple of A4 loose leaf folders

But think of the space I will create for yet more "stuff"....smiley

Hi, sorry to resurrect an old thread but...

Following 2 years (!) of prevarication about what to do about all these old volumes of ME that I have cluttering up my workshop.I have finally made a decision.

I realised that I am not interested in club reports dated in the 1980's and I am not going to be building a large traction engine or a locomotive of any gauge (well maybe a gauge 1).

As heartbreaking as I expect it to be, I have most of the 1960's, all 70's, 80's and 90's volumes but I intend to be ruthless and cut out all those articles that I want to keep (mostly George Thomas and Tubal Cain). I like hard copies but I may scan these in the future.

I shall create a filing process and store those articles that I am interested in such as tools, stationary engines etc.

I have done this last year with the EIM and Horological journal and to be honest it has created some space and I have not missed any articles that I have not, and never had been interested in.

Here goes....

I wonder what you all do with old volumes of ME's?

All the best

Derek Hall
