Since it’s out in the middle of the lounge, it might be worth reviewing the baseboard construction. It’s a bit experimental, and I would regard it as a qualified success. Those of you who follow my meandering waffle will know that I intend to build an extension over our garage, and that PD loco is a module intended to be a part of a future layout with rather more running potential. To that end, all the buildings lift off the baseboards, and the structure can be lifted without its legs, though to be fair, it’s large, unwieldy and despite my efforts, quite heavy.
The basic structure is a slanted “T” shape, made of two wooden girders. The top of the T comprises 62x38 studding wall timbers separated by vertical webs of 3mm ply 150mm deep.
sorry, photo rather dark. The ends of the beam are also 62x38 and form sockets for the legs to slot into. everything is glued - blue evostick weatherproof - and pinned with 1.25” panel pins.
the top & bottom of the main spine are rather larger. They are 150 x 20, again separated by webs of 3mm ply glued & pinned.
As you can see, the leg simply slots through a hole made for the purpose, its dowelled into a hole in the upper timber.
the spine is quite long - overall 3.6m, the top of the T is 1.5m, but the end is 2.4m from the rear edge, hence the “slant”.
initially I had intended to have only three legs, but fitted a fourth behind the turntable to add stability. Annoyingly, having cut all the timber correctly for the cantilever that joins the fourth leg to the spine, I assembled it upside down, so the leg socket was on top. To be fair, it was the end of a long day…. But that meant that the fourth leg is screwed on, rather than just fitting into a socket.
The baseboard top is also 3mm ply. It is supported on stripwood bearers that are screwed to the top of the spine, with some triangular webs to increase the stiffness of the structure as required, mainly at the back.
At the front, the stripwood is joined by a batten, and a thin strip of the 3mm ply was screwed to the batten ends to form the curve, and glued to the baseboard edge. I cut two 100mm strips of ply which I varnished as a front and then glued these to the batten & curved strip so no fixings show. Behind the fascia, I have lots of tortoises, wiring, and a curtain rail which allows the least scenic aspects to be hidden if / when we have guests.
The clunky great switch controls the led strip which is a useful additional light source on the workbench which is under the layout.
The electrics are DCC, so obviously there are only two wires…
The control panel uses an Arduino Mega to read the switches and connects via a CAN bus to the various Arduinos on the panel above the Lenz LZ & LV which control (L to R) the turntable, layout lights, and the points. Next to the LV is a Lenz USB/LAN interface which allows JMRI to connect to the layout,thus I can use it to program decoders, etc. The points are not DCC controlled, but if I built the CAN to X-bus interface, could be, I guess. On the right of the shelf is an old lab power supply which everything runs off. I’m going to get an arm for the control panel, as it currently sits on a shelf next to the workbench, and that isn’t ideal.
Weight-wise, with everything removable fitted, I can easily lift the leg at the thin end, and at the front of the T, the legs at the back are somewhat more loaded, and whilst I could lift them, I think I’ll enlist a few pals when it’s time to move it to the extension. Free beer & curry is most motivational, I find. I’m guessing that it’s probably 50-60kg or so.
Any questions, do ask!
