Welcome to the cameo competition
BG John replied to Not Jeremy's topic in Creating Cameo Layouts - The Challenge
I'll try to get a rough proscenium arch knocked up later, and see how it works. I got a bit carried away looking up the proportions of people, the normal ratios of head size to total height, and the position of the eyes in the head. Not sure it it will help, but it's kind of interesting! -

Does that help? You need a closed top on it to support the lights, to keep the glare out of standing viewers (and operators) eyes, and to stop uncontrolled light getting in. The only access is through the front. I think the book suggests that vastly overscale humans placing parts of their anatomy into the scene to operate it isn't what it's all about. I didn't look this up, as I've no intention of doing it! -

I'm currently getting confused by the 63" eye level, and trying to translate that into rail level! -
It's a long stretch from the bath to the switch. Someone could slip on the soap while trying to reach it.

Just appeared on Thingiverse is this working G scale Terrier. Something for all you new 3D printer owners to play with. The same person has done a Toby too, but you can print it without the face! https://www.thingiverse.com/thing:2689057 I must resist I must resist I must resist I must r...... Sod it, why should I?

A quick browse through the book to find guidance on dimensions for the proscenium arch came up with the following: Fascia elements “reasonably generous rather than erring on the skinny side” “Any fascia element less than 3 inches in breadth often look a bit wimpy” Start with 3 inches minimum for narrowest element, usually the layout profile fascia If topography is gently undulating, settle for 3 inches average If topography is rather more tortuous, go for 3 inches at lowest point Wings can be same width or greater than the fascia, and not necessarily symmetrical Proscenium is widest element, and set forward 3-4 inches to enable overhead lights hidden behind it to light front edge of layout The proscenium is the widest element and ideally needs to extend far enough upwards so viewer isn’t unduly aware of its top edge Avoid ‘tall but short’ openings Don’t normally consider opening with height greater than 25% of its length Opening of about 18% usually works for Iain Rice That seems to be about all the numbers the book puts on it. It seems like a good starting point, so I'll base my mock up on it, and see how it looks. Don't forget that the proscenium needs to hide the lighting. I didn't read that far though, as I'll worry about that later. Viewing height copied from competition rules: A ‘realistic viewing height’ should seek to put the ‘horizon line’ incorporated in the model as close as possible to the eye level of the viewer – typically, to a tolerance of +/- 2 inches. So the height at which the layout needs to be displayed for this to be achieved has to take account of how it is intended that it should be viewed, e.g., standing/seated on a high stool or seated at normal chair height. For persons of average stature, those alternatives typically equate to eye levels of about 63ins standing/high seat and 45 ins normally seated. I think I'll aim to stick rigidly to those heights if I can. Then I can pass the buck if anyone complains about the height! -
Coopercraft and Slaters et al

And if they got hold of the Coopercraft kits too, like they did with the O gauge ones.... -
I'm waiting until I get something working before I worry about battery charging. Depending on battery life, I may need some system like a section of live rail or inductive charging, but manually plugging in a cable, or even swapping batteries, may be perfectly adequate. The radio system I'm using is bidirectional, so the loco should be able to tell me when it's getting hungry.

I'm working through the book and making notes at the moment, or at least I would be if I hadn't got interrupted by food! I might post something later. -
I suspect that the weight of it would make most people's baseboards collapse though We're experimenting with it here too. See the Radio Control Forum. I haven't got it working yet, but Robin2 has.

I was wondering about using shellac to strengthen the boxes, but haven't tried it yet.
-
Is that OO, EM, P4, BG4, O-16.5 or O? Rumours that 7mm metre gauge may also happen on day may not be entirely unfounded! 7mm broad gauge has been on my mind too .
-
Other people have managed it . Anyway, Castle Aching is 4mm scale!
-
Radio control seems so much easier!

Looks like the same idea as these. They work, but you'd need to add physical stops to the knob to stop the servo in the same place each time. https://www.ebay.co.uk/itm/Multi-RC-Digital-ESC-Servo-Tester-3CH-ECS-Consistency-Speed-Controler-Power-NIUK/322815221119

I think needing two people to move it is OK. My main concern isn't transporting it to exhibitions, but getting it up and down stairs to the railway room. I'm not thinking about that one yet! On the baseboard height issue, I suppose a computer could be constantly scanning viewers to establish an average eye level, and raising or lowering the layout accordingly! The same mechanism could be used to transport the layout, using the baseboard as a trolley, then raising the board to viewing height when it's in place. Then just add a drive motor, sensors to detect where you are in relation to it, and some collision sensors, and you could walk into the exhibition hall with the layout obediently following . -

I couldn't find all the details I'm sure I read in the book, when I was setting up the board for my mock up. I know it's in there somewhere, so I suppose I'll have to re-read it! I'm building the mock up on a 6'6" x 2'6" door. The current idea is that the fiddle yard is hidden behind a canal wharf, so to comply with the one scenic baseboard competition rule, the whole layout will need to be in one piece. An interesting challenge in lightweight baseboard construction to make it manageable! Perhaps the fiddle yard will have to be a plug-in unit to keep the weight down. -
Many years ago, I worked for the UK subsidiary of an American company. The new President of the US company sent a memo to every company in the group, setting out in detail a new report he wanted produced. I got a letter from him congratulating me on being the only person who got it right .

Knowing the subject before deciding what to model can be a big help. A lot of BG locos look impossibly daunting to build. Would you want to build this if you're not a very experienced modeller? However, this could be a nice introduction to scratchbuilding. You could probably get away with using a simple OO gauge RTR chassis, like Hornby, with wheels refitted onto longer axles, and some added frames and spacers to keep the wheels in place. Or a OO gauge chassis kit with wider frame spacers. Maybe not the most finescale result, but perhaps a lot easier than many "narrow gauge" locos: Or this, perhaps from a OO gauge kit, again with modified Hornby or kit chassis. A Silhouette cutter should make the curvy splashers/footplate fairly straightforward. I have a cunning plan involving a Hornby 2721 Pannier: The first loco, and similar classes, were in widespread use in the earlier years of the BG. The second was a small class and unusual in not being saddle tanks. Their time period and areas of use were quite limited. The third is only suitable for the final few years of the BG. I've thought of Miles as being a good project for a micro layout based on the type of location it may have run in, where it may be the only loco. It's strongly recommended to use P4/S7 standards, to get wheels to fit in the small and very visible splashers, but Miles could be built to any wheel standards. Read books, search the web, study the BGS Data Sheets etc. There's a lot of information around (although still huge amounts missing). Find a little niche time or location where photos show things you think you could make reasonable models of, and have a go, to whatever standards you're capable of. You could even start off with a freelance Hornby Pugbash!

I wondered about that when I saw the photos. Surely you need more depth to hide the lighting. Have you tried lights yet? A suggestion in the book is to have the lighting set a few inches in front of the baseboard, so you don't get a poorly lit area along the front. Not having a dig at you, or anyone else, but I wonder how many people have really read and absorbed the book before starting their layout. To me, a lot of the entries appear to be conventional layouts, where "Cameo" features are being added later. I'm trying to design mine starting with the eye level baseboard, proscenium arch and all the other relevant features, and then seeing how my vision for the layout can be created inside that. Of course my layout hasn't been started yet, while other people are well advanced with theirs, so maybe it's me doing it wrong .
