With respect to the FF1001 it was a normal bidding process and there were several bids which led to these some 120$. I agree with Dick; its not ebay it's the collector's behavior. And/or a good made o

Thoughts on the layout of Vector sliderules: Here mainly S(R)T and different models
Hi, I have some private discussions with Maynard about usage of hyperbolic scales in the EE high frequency environment. In this context there also came up some points on the S(R)T scale. In the 4083 s

K&E 40923 LL0 scale
Hi, LL0: quite interesting that there are some model variations, and that different K&E models may concern also these variations: So far I've seen in the sliderule museum, the 4080 line always has bou

K&E 40923 LL0 scale
Hi Maynard, may it be that Trig on Body from 1933 was borrowed from the first K&E vector? The combination with CI gives a hint that there may be relations to the Darmstadt design, which came up in abo

K&E 40923 LL0 scale
Hi, may it be that beside possibly saving some space the more important reason may have been, that on the side of LL0 is only B but no C? If one may have needed LL1^1 then it is also possible with C

Multiplications and devisions with results on C (or CI)
Hi, the rules for multiplications and devisions which lead to a result on D are quite known. So far however I did not come accross any book or manual which teaches multiplations and divisions so that

The DI Scale
The N4 maybe belongs to these sliderules which look cool, but aren't then the favorite of some. A good question why. By sure on the one hand side the material, but maybe also printed scales with their

Hi Meine, yes a good point, that on the Faber 2/83N DI is on the side of the folded/speed scales. I think this is straight forward. Joe Herning once stated that there are two different patterns of sli

Slide rule scale names : Scale names of the flying fish 1002 and 1200
Hi, being now most time at home I use most time a flying fish 1002 rather than an Aristo Studio. Today I saw what actually is quite clear but which I maybe overlooked so far. I always wondered why on

The DI Scale
Working with resistors you maybe also sometimes have the problem that you e.g. look for 500 Ohm but first only find e.g. 600 as closest value. Now the question, wich resistor in parallel to achieve 50

The DI Scale
Quite an old subject... ...but I found a simple application where the DI scale is quite useful: Assume to have two resistors in parallel, e.g. 20 Ohm and 40 Ohm, how much are they together? The result

Improving sliderule skills / Slide rule juggling: Quadratic equations
Hi, Maynard pointed me to a mistake in my previous mail: It must read (110+sqrt(110^2  4*1000*2))/2000, of course. On the sliderule sqrt(110^24*1000*2)) by the way can be calculated by sqrt(4*1000

Improving sliderule skills / Slide rule juggling: Quadratic equations
Hi, Oughtred accused Delamain of "juggling". Sliderule juggling however may have advantages indeed. One example I came accross is to solve 1000x^2+110x+2=0. Calculation of the usuall quadratic formula

Thanks Alvara, with your plot it makes now sense what Gary Flom wrote. Well obviously there are points on the sliderule where two scales show the same value and by shure I could not tell that there ar
