If weight is the issue,why not try a different method of construction?
I've noticed that almost everyone tends to build tables and tracks that would probably withstand a nuclear attack, even if the track is only for home use.
I realise for the commercial raceways construction has to be heavy to withstand the depredations of the general public,but for use at home does it really need to be 3/4 inch MDF on a plywood base - and all this weight of course really does require a massive timber frame to support it?
I may be biased because here in the UK there is no such thing as even half decent timber. You can only buy damp unstable rubbish - and then you pay through the nose for it! So the pressure is on to find alternatives.
However, I've just completed an experimental folding portable track made from a slab of extruded polyurethane foam insulation board with a skin of 3mmMDF glued to the outside, and then routed.(I'll try and post some pictures as soon as I've recovered from the trauma of failing to get Photobucket to work - a real crash course in colloquial English usage that turned out to be! Even the flies on the wall were scared!).
The point, though is that it seems to have worked well.It is only 48x20 inches, and folds in the middle - but it works, and I think I'm going to try a bigger one next.
You can get these insulation boards in 8x4 here, and I imagine they come in the same size in USA.One rather slight person can throw one of these around with ease; and although adding thin MDF(or even thin plywood) would make it heavier, it should still be easy to handle.
Worth considering,don't you think?
