Walls and magnets.

A good week, thats the basic structure put together. Simple really, just put some plasticard on a nice flat surface and make sure it all goes together square.

I was concerned about the top edge and so decided to strengthen it with some brass strip. A thought struck me, why not use the strip to feed power to the fireplace LEDS? Now I wouldn’t want a soldering iron too close to the walls, so I soldered some sockets from a turned pin IC socket to the strip in the right places before glueing the strip in.

The LEDS for the fireplaces just plug into the strip.

Next question, how to hold it down. Back to magnets again, the idea is that these will hold against steel plates in the platform itself. As ever with my work I have a fear of not being able to get into things to clean or fix.

So, same idea applied to the roof.

The pic shows some 5x5x1 mm magnets on spacers glued in place. These pull onto the soft iron plates fitted into the roof itself.

Hard to get a picture , but you can lift the whole thing up and the magnets still grab, but a slight knock and the whole roof shifts slightly. As I have written before I’m getting a bit clumsy and this way might well reduce the chance of the odd knock causing damage.

 


A couple of pics roughly positioned on the platform.

Anyway, with all those windows I am going to have to model the interior reasonably well since it will be rather visible. Should be fun.

Excellent use of the magnets, and helping to stabilise the roof from knocks.

 

Do you find it awkward when removing the top structure ? Mainly thinking of resistance to the hardwork you've done vs. rigidity.

Now that is very clever. You do realize that with lit fireplaces and a removable roof, you'll have to detail the interior. And take photos and show us :-)

Well, time will tell bgman. The roof structure is very light and has a bit of flexibility. It has been on and off a dozen times so far with no problems. Magnet to magnet would be too strong I think, the soft iron transformer laminations give a solid but very localised pull. 

 

I have details for the interior Mikkel, essentially matchboard to dado height and cream walls above seemed to be the general pattern. The toilet areas were tiled in the same way as the exterior, though only the upper parts of those would be visible. Oh, and 11 panelled doors to make.

Superb modelling, and really like the magnet idea - nice out of the box thinking!
