All, Thanks to all who answered a rather obvious (in retrospect) question. Now, the follow-up question...Can someone give me an example of a rule with a...
We have just had a short survey about 'the most scales'. Now, which rule has the most hairlines on the cursor? John Mosand [Non-text portions of this message...
Yep. Use a good calculator and have a spare one exactly like it in the bag. Practice with it all the time till you get your P.E. I know, sounds like heresy......
... Done that. I knew it'd help later on when we go over the CI in ernest. Went a step further too. Remember, we're talking about a 12 year old girl-child...
Jeff, I agree with you about the margin of error with the "crowded" ends of the scales. Also, it rarely happens that I am simply taking a square/cube root, or...
Greetings Dave, The K&E 4053 series are all traditional trig scale rules, with exception of the D4053-3, which is a deci-trig rule. The K&E 4070, 4080, and...
John It depends a bit how you count them - some hairlines on a single vertical axis are split into 2 or 3 segments - but I suppose these should only count as...
The "traditional" trig scales are relatively common. I can quote as an example an Aristo 99 Rietz from 1961, a very popular rule. It also seems like some...

I personally use the A&B scales quite a bit and would miss them. On the other hand square root scales are very nice and so what I really like is a rule with...
On the earlier K&E's the scales were engine divided. Each scale cost money each time you made a rule. K&E did put a DI scale on the trig side. This scale...
Dave, I have two rules with "trig", not deci-trig, scales. These are a Post 1447 and a Hemmi 2634 pocket rule. The only obvious indicator is that the angle ...
Hi Jeff, I've never read this anywhere, but I've always assumed that K&E (as well as some clones like Sterling) left the C scale off the trig side was to make...
Actually "traditional" trig slide rules are still in production. The Concise 300's the group purchased last year have DMS type trig scales. Duane Croft ... ...
Adam, I have both the K&E 4081 < log log duplex decitrig > and the 4080 < log log duplex trig >. I prefer the 4081 because it gets more accurate than the trig...
Hi, Just got a Spring 2003 catalog from The Astragal Press and on p.2 it lists a new slide rule book (which I can't find, yet, on their Web site). The blurb...
Hi everybody, I recieved Aristo aviat 615, but I dont have a manual. I'm geting a little bit confused about some of the calculations. Could anyone help me?...
Thanks to Adam and Thomas for pointing out this was a Sterling-not seen one before so neither of my two lonely memory cells reacted positively! Now that I know...
Greetings John (and all)! Surely the FC 2/84 Mathema is the all time winner, with 39 hairlines on the cursor faces! This Rule is not a specialized type, it has...
So, we may have a winner in the 'regular' class? That number just happens to match my Aristo 920 in the 'special' class! It also has 39 hairlines, mostly...
Hi Jim and the list, this book seems to be the one which was published in The Netherlands in 2000. The subtitle is: "2 * 3 ..... approximately 6. Portrait of...
Sir, no promises but I may have one. You want a scan of it? I can try to dig into my library this evening after work. Rgds, Cthulhufatagn From: Antanas...

I'd be interested in reading the Aviat 615 manual too, even if I never get my hands on one of the rules in person. Dave...

Dear John I was looking at your calculation of (47 X 5.26squared)squared/(213 x pi) and I'm afraid the method you described seems to square the bottom bit as...

I saw the same item in Astragal's latest catalog-- I think its forthcoming publication was also mentioned in the latest issue of either J. of Oughtred Soc. or...
Sir, as soon as I recv all emails confirming who wants the scan i would do the scan and send them off. Rgds Cthulhufatagn. Beware:- Singapore is one of the...

Visited the Arch is St. Louis over the weekend. Took my kids up just like my dad took me up 30 years ago. In the waiting area for the north elevator there is...
Greetings Doug, I will give you a bit of the history of that fine Arch you visited. I was born in St. Louis, MO. My grandfather, Vincent O'Leary, used to...
