Layout Version 3. Baseboard begins.
Some significant changes were made on my layout plan since the last revisions (incomplete threads here: https://www.nscale.net/forums/showthread.php?t=13019 and here: http://nscale.net/forums/showthread.php?t=14484. Note: some posts are missing I think due to the migration to the new forum some months ago).
Why the change?
The major change has been a reduction of the overall layout size. I have decided on a single module 2000 x 700mm, rather than an "around the wall" layout and I made this tough decision based on three important factors.
Firstly, embarking on a large "around the wall" layout would open myself up to a significant amount of work; more work than I have time for at present and indeed may have in the medium-term. I want this layout to be an enjoyable experience and not become a burden on me. I could clearly see myself not completing it. Secondly, creating a single module layout of this size would give me the opportunity to (hopefully) easily transport it to an exhibition in the future. Lastly, the all important factor: cost. I really had to consider the amount of money I would pour into the layout, and a smaller layout naturally means less construction costs.
Now I have decided 100% on the layout size, I dot-pointed what I wanted to include in the track plan.
- A continous oval layout with two track storage sidings concealed behind the scenery.
- Now that I have several Trinity corn syrup tankers, A HFCS (corn syrup) transfer yard such as Model Railroader's Model Railroad Planning 2010, page 68. would be ideal and I think a bit unique.- A small classification yard which also serves as 3-4 unloading dock for road transport. I haven't decided it purpose at this stage.- I need to change my mindset from my original large-scale plans, where I was going to include everything; several industries, classification yards, the whole box and dice. I need to make this layout uncomplicated and uncluttered.
- The photo of a small layout Model Railroader's 102 Realistic Track Plans No. 5, page 24, gives a good visual indication of what I hope to acheive.
- Atlas track and points and Tortoise slo-motion switch motors.
- BN mainline with Wisconsin Central for a shortline/switching.
- NCE Power Cab for DCC which is more than adequate for my needs. I envisage I would be running no more than 3 locos at any given time.
I need to admit up front to you all that I am a stickler for detail. I over-engineer anything I build. Anything. If it needs two bolts, I put in four bolts. I also wanted the layout to give the presence of a piece of furniture, not some ratty ol' slapped together pine frame. This is my over-engineering brain kicking into gear.
After several false starts experimenting with different timbers, I decided on Victorian Ash, which is a local Aussie hardwood from south east Australia. I used 90x19mm for the outer frame to create the module. Inside are two equally-spaced support beams using 65x19mm. The top face of these two support beams are 30mm lower than the top face of the outer frame. I did this to allow the polystyrene base material to be recessed into the baseboard. I then cut to size a piece of 5mm MDF sheet and place it inside the outer frame, resting on the inside support beams, then glued and nailed in place. At this point I polished all the timberwork with linseed oil and rubbed dry. The linseed oil really brought out the grain of the timbers.
At one end I routed a neat hole to mount the NCE DCC panel.
Finally I cut to size 25mm (1-inch) polystyrene sheet and glued it to the MDF. The polystyrene protrudes about 3-4mm above the outer frame.
I have fitted cable clamps along the inside of the frame to run the cables.
I will attempt to scan my pencil schematic and post it in this thread shortly but in the meantime here are some pictures of the baseboard constuction finally near completion.
At present the baseboard is resting on my old pine version. I will construct some nice hardwood legs and supports next week.
I hope the images make sense. The complete baseboard is currenntly sitting on the old pine basboard until I can construct some hardwood legs.
