Conversion Chart

[jason udallParticipant @jasonudall57142]

Just one point… have acare what is printed on reverse..( ideally more of the same) since if cuttout to bind seperatly then don't want to wreck rest of mag…

[David Clark 13Participant @davidclark13]

Hi Jason

The idea is to photocopy and reuse.

However, I might be able to arrange that adverts are printed on the back.

i dont want to be paying for anything i that i can already get from the internet with a little time spent searching. if all these charts are going to be taking content away from the magazine that i pay for then im not interested in any way.

im quite happy to accept them as a free pullout in ADDITION to the regular content, which is what i thought we were all talking about in the first place, but NOT as a replacement for regular content.

[I.M. OUTAHEREParticipant @i-m-outahere]

I don't think the Editorial team would remove any of the content just to fit in a chart but rather use this as filling when there is space to do so .

If a few of the regular advertizers come on board and sponsor them then everybody would benifit as well.

Having something like this could help to fill the center fold of the magazine when there is space as not all article fit together perfectly as some are one page only and others may run for a few issues .

In the long run we will never lose as we have no control over the content anyhow !

There are articles that are interesting to some and not the others so we just have to cop what we are dealt .

I know that there may be some who have every chart ever written and may not need these but there are the newcomers who may not have the technical library , money or time to source these and therefore would appreciate MEW doing these charts .

There is a lot of info on the internet that is wrong or unsuitable for Model Engineers so as David mentioned earlier in this thread some one will need to check them .

I subscribe so what ever is in the Magazine is what is – so if i want to see something in the Magazine i let the Editor know so that they can keep an eye out for relevant articles .

Thanks to Slotdriller for stating what must be the right attitude to the content of "MEW".

I've been rather surprised and disappointed at some of the posts above which have more or less said "well I don't want these charts unless they are in addition to the normal conent of the mag because I can look such stuff up on the internet any time I like".

That must be, as Slotdriller has pointed out, a very unrealistic approach. The publishers of "MEW" are producing the mag to make money. Their beancounters have done their sums and know the cost of paying the authors, typesetting the pages, printing and binding them, then distributing them. Those costs are offset against the income of subscriptions, "casual" sales from bookstalls, and advertising. Hopefully that total income exceeds the total cost by a margin, otherwise no profit.

The only control of these costs and incomes the publishers have in advance of producing the issue is in limiting the number of pages they print for that issue. Get that number wrong and the publisher soon goes out of business (examples of which we have all seen over the years).

In the case of "MEW", David has told us that the "magic number" is 68 pages and all he has done is given us the opportunity to say in advance what will be the content of some of those 68 pages. Change that 68 page "balance" (even if he is able to) and the bean counters will NOT be happy bunnies – for obvious reasons!

For someone to say that they don't want a certain content is, IMHO, complete nonsense – especially for the reason "because I can look it up on the internet". One can look up anything one likes on the internet today, and a lot of that will have nothing whatever to do with models, engineering, or workshops! The internet is one of the problems all publishers are facing today, so in effect, anyone who buys any magazine is actually buying it IN SPITE of what can be found on the internet. That's each individual buyer's choice.

To me, all that has happened here is that in David we have an Editor who is decent enough and aware enough to ask us in advance what we want part of those fixed 68 pages to consist of. How often does that happen with any other magazine?

To respond by saying "I don't what a certain content unless it is additional to the fixed 68 pages" is completely unrealistic as well as unreasonable.

My thoughts for whatever they may be worth.

Thanks David Clark.

Can I introduce a word of caution regarding charts. I have a whole collection of the cards provided by MEW in the past to form a workshop data book and I don't think many ever get read. By all means have a few charts, but stick to things that get a lot of use in the workshop and don't let the whole thing grow like topsy.

Well said, Doug

Hi There

You are all ovelooking the most important thing.

NOT EVERYONE has access to the Internet.

More people think the charts are a good idea than the few who do not.

I will be creating the charts, I do not get paid any extra.

Yes, they need to be checked and I do need to go back to first principles so I can't be accused of copyright infringement although I doubt you can copyright a list of constants.

Also, you, the readers, will have a say in what we do decide to publish.

regards David

[SteveWParticipant @stevew54046]

Its most useful (to me) if tapping drills etc are all metric but I guess some will prefer imperial depends on your drill stock! I would find % engagement sizes particularly useful.

This will be a useful starting point for a magasine as so many people have contributed their views before the publication – something not often available for the editor to consider. Hence I'm looking forward to it!

[David Clark 13Participant @davidclark13]

Hi SteveW

Imperial and metric will be given.

Although it's fair to say that everyone contributing to this discussion does

Seriously though, David … the Shetack circular device [as shown earlier in this thread] is the best implementation I have ever seen. I still use the one inherited from my Father.

Instead of simple charts; could you maybe produce a pattern for something similar ?

For info:

It turns out that the "Monument" version of the Shetack DTC is the real thing …

Bob, please can you do a higer resolution picture of the disc thing, perhaps just the sector and a bit of the scale would do.

Hi Bazyle,

Here are pictures of both sides of my, rather old, Shetack. It's not identical to Bob's, but it does have Metric data as well as Imperial.

[Speedy Builder5Participant @speedybuilder5]

Gary, check your PMs, or look at my album postings. The last 3 photos are from my SHETACK calculator.

[SpringbokParticipant @springbok]

Hi David,
Still think that this a great idea ignore the ChEEP CHEEP's as I call them more noise than anything elso. The new people and even me who still has to go to old charts for example what drill do I use on a 5/16"ME hole to tap!! I am quite sure that many of us would not know that of the top of there heads, But I am sure some smartarse will tell me once he has looked it up.

Have you got an old Blackgates cat as this gives all the ME data on there back page.I can send you all the dsts that I have if you all of my dataif you are interested.

kiind regards and keep up the good work
Bob

[WolfieParticipant @wolfie]

I'm definitely up for this, especially BSW/BSF tpi for identifying old bolt threads etc

[David Clark 13Participant @davidclark13]

Hi There

A reader has complained to the Managing Director that 80% is an incorrect percentage of engagement for threads. Despite that I explained how to calculate different percentages of engagement.

What are your opinions on percentage of engagement for ME threads as used for boiler fittings.

regards David

[PackmuleParticipant @packmule]

I use the following :**LINK** just copy and paste what you want. hope this helps. Bob sorry for the layout ,I can't get the return key to work when posting

[John ShepherdParticipant @johnshepherd38883]

David

Tubal Cain recommends 65% engagement up to 3/8 and 70 – 75% thereafter in the Model Engineers Handbook but that is not specific to boiler fittings. There is also a table for the % engagement for different materials that ranges from 50% to 75%. The only mention of a figure above this is 85% when tapping sheet steel when the thickness is less than the core dia of the thread. (I believe these are recommendations for use in the home workshop and not those used in production engineering).

Hope that helps

[mechman48Participant @mechman48]

Much as I support & welcome Daves idea for inclusion of charts; look in Roebucks 'ZEUS' pocket book (usual disclaimer).. available on flea bay etc, it has everything you would need .. tapping sizes, drill coordinates for jig boring, trigonometry, tapers, BS 4500.A ISO hole & shaft fits, etc,etc. The latest version I have.. metric revision, now includes – symbols & abreviations used on Engineering Dwgs, Misc' function words from USA-EIA standard, G code addresses for NC, letter addresses used in NC..

Cheers

George

[John McNamaraParticipant @johnmcnamara74883]

Hi David Clark

Good to see you back in the shed……

If you do decide to include charts How about plasticising them so that they keep clean. It would cost more but maybe the advertisers could use the back (Only please). Would that earn enough to pay for them? IF so you could make it a regular feature.

Cheers
John

G'day

Although this is not a chart (of which I love the idea), it is a really good unit converter. Lol, it even does light years to millimeters. **LINK**
