Sadler’s Sidings – 02 – The Basic Modules – Drawings

G’day All, The modules that form Sadler’s Sidings have been developed over a couple of years of playing around with wood moldings, plywood, balsa sheet and other stuff in order to create a robust and light table top modular system which is suited to quick set up on the kitchen or living room table and is easily stored away. The T-TRAK modules are excellent for most purposes, as my working with them for over 10 years proves, but when it came to creating a small switching layout that could also be packed into comparatively small boxes even T-TRAK modules were too large. I also had in my mind my days as a tertiary student living in student accommodation and shared houses where most major woodworking tools were hard to store and use. These modules can be built using glue, small clamps, small mitre box, small saw, craft knife, steel ruler etc and the materials can be bought at hardware and hobby shops.
If they develop into a modular system it will be known as `SideTrack’ to fit in with the concept of making shunting layouts that feature sidings rather than a main line or branch line focus.

The basic frame, reinforcing spine and corner blocks are all off the rack timber moldings. I first used pine moldings but have found that they are often a millimeter two smaller than the stated dimensions. Hardwood moldings appear to be more consistent.
The top surface is 3mm thick balsa wood mounted with the grain running across the width of the module to gain maximum strength. 3mm ply could be used but it is a real pain to cut with a craft knife compared to balsa.

VERY IMPORTANT: Do not fix the central `spine’ until you have mapped out where you will have under the surface items, eg. magnetic un-couplers, switch(point) motors etc. You may need to move the spine to make clearance ofr them, as I discovered the hard way!

The width of 125mm just `worked out’ as I considered balancing the need for space for the actual industries against the need to have comparatively narrow modules for easy storage. The O scale equivalent width is 500mm and the experts in that scale can create quite adequate shunting layouts with that dimension – eg. Bury, Thorn & Sons at:
Basic Sidetrack Module 125mm wide
Basic Sidetrack Module 125mm wide

The length of a module is a multiple of 50mm less 2mm to allow for the Kato Unitrack to overhang the ends by 1mm at each end.
The next BLOG post will be photographic description of actually building one of these modules.
