I've got the job of making the test tracks for my local (American interest) club and need some help. We've decided that in order to accommodate at least 4 different scales (O, HO and N with 10.7mm gauge as well) we need to have boards which are 400mm wide and a 'standard' straight length of 120mm. Curved sections will be 8 in number based upon the outer section being O gauge with 45 inch radius (we've already tested long stock on curves which are 38 inches so the 45 should be more than adequate).
There will not be any need to add any ballast as the whole thing must be as light as possible so that it can be transported as easily as possible.
- There has been some discussion about the best material MDF or plywood. We will probably use 4 or 6 mm thickness. Your opinions please.
- Where can I get some O gauge flat bottom track? (Peco only seem to produce bullhead rail and the one member who has a large amount of O gauge claims that the sleeper spacing and rail profile are wrong). I'm quite happy to use setrack for the curves but would like to be able to get straight track that fits onto our 1200 mm standard board section length without cutting.
- Where can I get some copper clad paxolin already cut to size suitable for making a joint 16.5 / 9 mm track in code 75 or similar. (this will probably be the last stage as we intend to use flexitrack for the 'single' HO and N scale tracks; the multigauge track is for additional usage on busy nights and also for testing HO stock on the smaller code
- Where can I get some code 75 rail for No 3 above.
- Anyone know if it is possible to buy a roller (or similar) gauge suitable for dual gauge 16.5 / 9 mm or will have to make it myself?
- We will be using code 100 16.5 mm track for our HO test track, probably PECO unless anyone knows better product. (We decided not to use code 83 as it comes off the sleepers too easily)
- Any suggestions for location dowels or other systems that will be easy to put together for accurate rail lining up, and take years of weekly setting up and taking down.
- I'll probably use flat brass or NS metal screwed to the baseboard edges with the rails soldered to them to ensure rail alignment. Anyone know where I can but some flat brass on the cheap - preferably in strips so that I don't have to mill it down to size. Any one got any other ideas for lining rails up.
- Should we use cork underlay which is normally used to provide depth and ballasting and for sound deadening purposes.
Anyone with any suggestions which I need to consider before final decisions are taken prior to construction.
TIA
Mike
