Finally baseboard construction has begun. I have had the plywood 8' x 4' or 2400mm x 1200mm for a few weeks and to make the baseboard framework I needed some extra timber. This was supplied by cutting down some long lengths of pacific maple timber. I transported the timber in the back of the Corolla down to a mate who had a table saw which made quick work of cutting up a boards 240mm wide into three x eighty millimetre wide boards. The beauty of the pacific maple was two fold, it was free and it is a very light timber which was ideally suited for the baseboard.
With this layout to be built I have decided to make the baseboard user friendly in that it will rotate to enable me to work on the underneath of the board without laying on my back or straining looking up from underneath. When considering how I was going to make this work the first thing I thought of was to drill a hole through a centre pivot point and insert a wooden dowel so that the board can be rotated 90 degrees to enable it to be worked on. Not having any dowel on hand I could see me having to buy a long length just to get a short pivot piece. I then threw the question at Google something like 'rotating joint/coupling' and what popped up in Ebay was my answer, it was a lazy susan mechanism.
So an order was put in and not forgetting that I had to order two of them. They soon turned up and then after playing with them in my mind I was soon asking how do you screw in the second disc when the first one is already screwed in? It took a look at Youtube to solve the answer in that a a second hole had to be drilled into one of the sides to expose the 'other sides' hole. Harder to explain in words, just check out Youtube if interested.
Once again I have been rescued by using old baseboard timbers that previously formed part of South Coast Rail. These timbers originally came from a next door house construction as they were apparently made to the wrong size. As they were going to be scrapped I quickly grabbed them for future use. They now have notches from the previous layouts baseboard in them but I will fill these in with some offcut timber and make them all look nice. The baseboard framing has to be made upside down as the centre leg is connected to the end timbers. When it is all done then it will be flipped over.
In another 'doh' moment I was going to have the centre leg on the inside of the baseboard but soon realised that when the ply was attached and the board rotated the leg would hit the the underneath of the ply. After cutting off the top of the leg I soon realised that if the leg was on the outside of the frame there would be no problem, so that's where it is going.
As can be seen in the above photo it looks like the plywood is not large enough but as indicated in the previous post, the Electroliner has made me go to 10" radius curves to enable it to run and therefore I needed a bit of extra room to accomodate this aspect. So I have made an extra 100mm in width and also 200mm longer. The theory was that the whole project could have been larger as I have the room but there is a handling limit to a single baseboard size.
Now that the outer frame has been made I need to put the ply down and design the final track layout. If I just spaced out the other central supporting timbers sure as Murphy would put a timber right under a point construction. So the layout will be designed and can be modified if necessary to accomodate the timbers underneath.
There will be a connecting piece between the two upright timbers (and be on the floor) shown to support and stabilise the layout.
The above photo readily shows the extra baseboard length and width I have grabbed. I will need to source some extra 9mm ply and fill it in to the edge. I am planning to try and incorporate a hill up one end and get away from the complete flat look. It will also create some interesting scenery features, and just hope the Electroliner will get up okay.
So that's where I am up to at the moment - out with the rulers, compass and anything else I can think of to design a good layout.
