Comming from a Wargaming background re-configuable terrain is a must. The is OK with Sports track save for one issue ,elevations. All the current means of elevation take time and fiddlig save perhaps the Slot brick method. The other issue is borders. None of the standard methods seem to work well for borders on scaley track (there I may be doing Slot Brick a diservice sorry if I have). So what of a solution. My latest idea just tested 2 min ago seems one possible solution. I have glued N30 (rare earth) magnets (dia 3mm thickness 1mm) static pull 0,3 kg into the underside holes designed for flyover pegs, in a standard track. These magnets pull on clout nail heads mounted in 3mm Hardboard the width of the track plus borders. In my case 2 straight lengths with tapers curve entry and exit borders either side. Two track lengths is enough to do my flyovers at 75mm tall (small area no room for 3 track up-slopes). The magnets help to keep the track position on the hardboard. Using hardboard I can supports the track and borders effectiveley with few supports and means the high curves can be drifted like on a fixed track. To cut assembly time down "on the night", many of the hardboard sections will be for more than 1 track piece. The Track is not bespoke as the magnets is all they need. It looks to be a good compromise between fixed tracks and standard scaley. IF anybody thinks is a good idea, maybe 0.4kg or 0,6 kg magnets might be better but then there is a dangers of bending the track lifting it off the hardboard. Also the magnets I used were cheap about £7,00 for 100! Comments and ideas welcome.
