I've built my Scalextric classic/SCX Chrono rally track with some quite severe (for plastic track) gradients. The curves in that section have home made borders, which I did by cutting hardboard to fit under the track and then glued the borders to. So far, so good.

The problem I'm having is supporting the borders. I've had what seems to be a daft idea:- What about spraying Fill-A-Gap between the table and track? Because the track has the hardboard under it, the foam will not be able to get through the track webs and into the slots - so that won't be an issue.

Has anyone tried anything similar to this? If so, was it successful?

TIA
Stuart

I'm guessing your 'Fill-a-Gap' is expanding foam. It's commonly used for rocks and filling voids in the track. No reason it won't work for the job you describe.

Thanks for your input.

Stu.

Just a word of caution mate with the foam. Use the gloves that come with it, normaly in the cap. Your hands will be stained yellow & black for weeks.

Also wait 48 hours before you cut the dried foam, small bits will have gone off overnight but the thicker bits can still be soft in the middle.

Cheers

.... and be careful if you're squirting it into a tight space between surfaces if they aren't completely rigid. As it expands, it can push things apart (learnt this the hard way

)

I was going to suggest something to hold the track down as well. If the track is just floating, not stuck to a sheet of wood or something for support, then the foam will easily lift the track as it expands.
