Sir Lamiel’s 777 Quest - A Scale7 Micro Layout Challenge

Is there an easy way (program ) which works out sq feet other than basic maths

I have an idea.

I was thinking how awkward 7 square feet is with metric board sizes. Then I realised a circle with a radius of 300 mm has an area of 0.28 m2. And so a quadrant is 0.07 m2, and this ties in with the 0.65 m2 from Fraser.

If you start with a "metric 4 x 2" baseboard, this gives 1.2 x 0.6 = 0.72 m2. So if you remove one such 300 mm quadrant, e.g. with the backdrop or one front corner, you get 0.72 - 0.07 = 0.65 m2. Which is 7 square feet :)

Addendum: sorry but these calculations are all wrong, see this post.

Please what is "Scala Septem Sancti Graalis"?
I went to a state school and we didn't do Latin there, and Google Translate says "The Seven Ladders of the Holy Grail" :confused:


@RichardG - If it is any consolation I went to a state school and suffered the misfortune of masters trying to teach me Latin - I hated it! But then it was all a long time ago and since then ideas about education have changed somewhat.

I hesitate to butt in as a non-S7 modeller, and permanent resident of The Back of The Class, but the usual definition of a true "Micro" layout is a layout of 4sq/ft or less in area. 7sq/ft would more acceptably be described as 'minimum space' perhaps, especially for a 'proto' scale such as S7.
Of course an 'ordinary' O Scale continuous run layout in 4 square feet, without specially modified stock, is impossible, isn't it. :))

Except I built one - a dual-gauge 32mm & On30 'pizza' on a board 2ft x 2ft....

Ok I'll get back in the Naughty Corner now & leave you all to it.... :oops:

Except you have removed the area outside the quadrant. 0.3 x 0.3=0.09 therefore 0.09 - 0.07 =0.02, 0.72 - 0.02=0.7, so still a bit big.

the concept of 7 small measurements in one measuring system being used to represent one unit of a totally different measuring system would probably have fried their brains

The task of designing something of (up to) seven square feet using metric sizes of baseboard kits is frying mine. A spec of 0.65 m2 is an ugly number but somehow I expect I will find it easier to work to in the long run.

Take the empirical approach - if your first radius gives a slightly too large area, try a bigger radius to give an area too small, and then hone it closer with another.

I’m planning to use 2 x 900x400mm boards giving 1800mm length and scenically cropped to 361.2896mm depth!

Erm, what’s Ecxel, Simon?

I’d have qualified that earlier post but unfortunately- as wot I wrote elsewhere - this iPad thingy is playing up and sadly ran out of ink, and I’m in the process of replacing it.

Indeed, Latin.

As a Roman Catholic, my faith and the ‘language’ were inextricably linked, or so it seemed as a child. I recall - at around six or se en years of age - having to receive ‘lessons’ over a six week period to recite prayers at Latin mass (as it was back then) before being allowed to serve on the altar as an altar boy (weddings and funerals paid well and I looked forward to the annual altar boys outing).

But then my brain links it to school where we received Latin lessons, which links it to the ‘Christian’ Brothers, then a Boarder and homesickness, muddy rugger pitches and an overwhelming sense of anxiety which I don’t think has ever left me, my friend, which almost culminates in ‘diaphoresis’ (cold ‘sweats’ to save anyone -bothering to read this far - checking it out on Elcex).

Perhaps I’m suffering from PMT or whatever it is those lawyers are increasingly using in mitigation in court these days!

Not aimed at you particularly, Simon, as you’ve merely entered into the spirit of things with your post, but as a casual observer of the human condition, the only Latin word to strike a chord with me was ‘praetendere’, which I’ve applied - quite accurately in my humble - to those I’ve had the misfortune of meeting over the years who like to ‘spout’ the stuff, especially where there’s an audience.

Bless ‘em.
