Useful MEW Table

Hi MichaelG, thanks for the appreciations of the scans that I did, I must admit that I'm a bit of a perfectionist with most of the scanning I do, these ones took three separate successful scans stitched together to get it to my satisfaction, but it was fortunate that the chart had never been removed from the magazine prior to me scanning it and so it was in almost mint condition and needed very little tidying up along the fold and the staple holes.

Regards Nick.

I have one of those behind my lathe.

Laminated onto Melamine facesd MDF and then sliced up to fit.

regards Martin

Being a newcomer to the model world, I have been looking on the net for drilling and tapping sizes, recently I found this among some lathe bits and pieces and I think it’s really good. It must be a few years old because I’ve had it about 30 years.

So of course the original chart I searched 4 is somewhat useful, but basically a drill sizes in decimal, metric, fractional and letter sizes. Possible to get some tapping info from, but a real pain in the proverbial. Journeymans chart has EVERYTHING, but in a readable size would probably paper the outside wall of my garage

What I really wanted was something you vould easily read the tapping drill for any common thread from, with ease.

I think I have found it, and here is one of its two A3 pages.... hope I got the photo load correct!

Forgot to ask: does anyone know which issue it was in, and/or have a good scan file of it? The pic was of a not- fantastic quality photocopy.

Look back at Nicholas Farr's post of 9th December 2020, timed at 00:51:50

This quotes the three Issues of MEW when the charts were issued.

Zeus Charts? Don't knock 'em.

They are handy pocket sized.

Still using mine (rather grubby ) from 1958!

Howard

OK I see his two charts were in issues 134 and 135 - but why cant I see them, or at least photos of them?

Michael

I have one of those Tracy Tool poster-size charts hanging up in my workshop, suspended by an old dress-hanger.

If it's really only tapping-drill sizes you need, you could create a table on an A4 sheet of the relatively few for 90% of your work, as that would be quick and easy to read, and leave the reference-books in the house for the odd time you need something else. Make a smart-looking printed form and laminate it, or just hand-write it and keep it a clear polythene bag.

When I made my workshop's travelling-hoist (all Metric screws), I wrote the 3 or 4 tapping-drill sizes needed, in big felt-tip pen characters, on a scrap of white building-fascia plastic and propped it up on a convenient ledge!

And yes - I have a couple of Zeus books - one in the workshop, other the lives indoors along with my engineering library. The only thing is that over the years the numbers have shrunk... (Rather as big lathe chucks become heavier.)

@ Michael Belfer

For clarification ... Have you followed the link in Neil’s post ?

MichaelG.

Last couple of Issues of MEW also have some charts being printed in them that will form a booklet.

Michael G - yes. I had the drill equivalents table loaded and printed in A2. Guys responding, please, no more on that table please?

But if you look at the photo i uploaded yesterday, you will see this is a totally different chart - it is headed BA & British Threads. full of really useful information about a wide range of threads. The link Neil posted is a table of mm-decimal drill equivalents but, now that I have used it a few weeks, I see it is not all that easy to use for tapping information - in fact it has not much tapping info.

Harold Lewis seems by to think that Nick quoted the issues 134 and 135 as where the tapping table was printed first - In fact he refers Maurice' photos, which as far as I can see are, yet another upload of the DET (drill equivalents table)

So again, does anyone have good scan or copy of the chart I pictured yesterday, the BA & British, that may or may not have been in issues 134 and 135 (Nick didnt show it, Marice does not seem to have in his album

And NO, Nigel I really dont want a partial chart , I want it all in one place - there is no substitute when sorting fasteners or selecting a size - a comprehensive table arranged in order of size is the most useful. If no-one has access to the BA&Brit, I will get the A3 copies I have laminated onto heavy card

Michael B

PS Jason, the current pagefillers being reprinted will be quite a while (months) till the set is complete, not that easy to read, and seem to be in subtables by thread families

BA & British / American Threads / Metric Threads was printed in MEW 230 as a double sides ctr fold pull out

Sorry ... my misunderstanding

MichaelG.

Found this one by chance the other day: Link

That should lead to some imperial to metric charts...

Thanks Henry, not what was looked for. But thats the easy part - 4 psges in the middle of the MEW issue 230, even in the archive!

The hard part ( so far i cant achieve it) is somehow getting the 4 pages into a decent quality print, preferably A2, but I would settle for A3

Apparently the archive is designed to circumvent printing.

Michael

Accompanied by sound of forehead being smacked: Turns out that unlike my normal habit, I left the issue 230 centrefold inside the mag, so I will now get scanned, printed and laminated professionally

Worth noting, the table vontains at least the following errors:

a) first two entries, 16BA and 15BA have an extra zero in the diameter, so note the diameters are NOT .08 and .09 mm. I corrected on mine with white-out

b) Top of page 2 of 4 has the entries for 1/2X28, and for M7 coarse and fine; these are way out of correct place in table. Harder to fix so I just marked the lines with asterisks

RE BA, BRITISH, USA and METRIC Threads Chart from issue 230 of MEW

Anyway, I have the chart ( marked with a few small corrections), in a pdf file of some 5-6Mb. By far the most useful tapping info chart I have found; includes many British, USA, and metric series threads, in one table sorted in order of Outside Diameter

Anyone desiring a copy, email me off- list.

Neil also has it, and it will probably find its way onto here sometime

Michael

I have such a chart on the back of the workshop door.

I sent you a ‘Personal Message’ on 21-03-2021, Michael

... but it remains unread

Grateful for a copy of the file when you have the opportunity to send it.

I fixed about 20 data sheets on A4 pages in book form to cardboard backing sheets and hinged it on a cupboard door in my workshop so I can easily flip to the page I want; the page is held in place with a spring clip. This way I only use the area of two A4 pages. Colin
