Hopper, where did you get your latest Zeus and how much was it?

Google 'Roebuck Zeus data', lots of suppliers (including 'Roebuck' in the search is essential)

[mechman48Participant @mechman48]

I got mine from 'Roebuck'… cost in the region of £5.99p iirc, but there again a search on e bay would bring up a cheaper price no doubt.

It does seem a bit strange that it carries a banner "Metric Revision" nearly 50 years after we went metric.

Remember Roebuck are American!

Just a quick update and David Standing is quite correct. I had read largest collet as 1 1/4" when it is actually 1 1/8". All 66 new collets have finally arrived and I am much pleased.

Rik,

I'm delighted to hear that the collets are good: But can't resist the temptation to mention that

"Let he who is without sin cast the first stone" might be relevant.

Thanks to John Fawcett who sent me a handy conversion table for his Myford collets.

You can download it here:

Wow, 12.7meter collets and I thought that 1 1/4" 5c was big

[Nicholas FarrParticipant @nicholasfarr14254]

Hi, getting back to the Zeus error, my 1978 one that I've used at work for donkey years, has a more serious error, or more to the point, three on the same page. This gave me a real head scratching, thought I was losing it kinda feeling a few years ago. I was trying to calculate an angle for part of a fabrication, but the answer that I kept getting was ridiculously incorrect, time and time I tried, but just couldn't get a sensibly result, even making sure that I was calculating by the correct formula. Turned out that the information in the Zeus was wrong.

Sixth one down in the Data Known column, the letters were both incorrect, can't remember now what they were, but I scratched them off and wrote the correct two in. Also noted that on the same line, three across, it said Cos B when it is Cot B and the same thing in that column on the ninth line, which had Cos C, which it is Cot C.

The calculations came correct once I had the correct formula.

Regards Nick.

Just for FYI / clarification, from my metric revision…

George.

[Mick B1Participant @mickb1]

Gah.

Another of my lifetime certainties destroyed.

No wonder we lost the Empire.

Where's my revolver?

[Rik ShawParticipant @rikshaw]

I have just found a fifth version of Zeus I had forgotten I had. This version is even older and front and rear covers are a delicate shade of green a' la Woodbine fag packet. It is the "Unified Edition" and marked "COPYRIGHT 55" (1955 ?)>>

Funnily enough none of the aforementioned mistakes mentioned in this thread appear in this older edition.>>

But as far as data tables go, my ancient and tattered copy of ME plans catalogue from circa 1984 has very clear tables and I still use it on a regular basis, pity it is no longer published.>>

By the way – does anyone know when the first Zeus book was published?>>

Rik>>

[Mick B1Participant @mickb1]

It's a pity Zeus no longer print full details of BA threads. For some dimensions I have to go back to my extremely dogeared and tatty 1977 Dormer Tap & Die booklet.

[Ron LadenParticipant @ronladen17547]

Can anyone tell me what is the latest revision.

Thanks

Ron

[mechman48Participant @mechman48]

Have a look at …

**LINK**

​this is the version I have so may well be the latest, It does say copyright 95 on the back cover so I assume it to be the latest version.
