Hi this is my first attempt at building a track so I thought a single lane rally track would be the way to go.Slot is now done ready for the rebate and the marking for the track profile cuts done. Used 6 mm board thinking it would be easier to shape but then found out I had to brace to support the slot. As I had drawn the track the way we had planned it to go it soon became the opposite way when flipped .The bridge section is ready for cutting out once I have done the rebate. What depth rebate and what would be the best way to fix it to the track ( tape or Contact)? Lane length is 15.97m Any ideas or advise would be appreciated. Going to use 3/16 braid and still trying to work out what timing system to use. Have downloaded to my phone Slot Car Trainer to try when the track is ready for the first run. As soon as I can work out how to post pictures I will add a couple of the first stages.

I would look at Race Coordinator for a timing program, very good for timing and race control,will run off a PC parallel port with no interface.

G'day Greg ,Interesting build so far by the sounds of it. I'd get the braid and measure it before routing the rebate, keep it level with the surface(over is better than under if it is for 1/32 only).
I use 3M tape but seal the mdf well, main reason is that it's easier to reuse the braid for your next track which could be sooner than you think LOL

Thanks DM.

Hey Greg, looks very interesting with a good mix of straights and curves. What is the tightest radius?

Well done ;)

thanks for that Dave will get the hang of this soon. Elevation car end will be 300mm and the bridge area will be where the sandpaper is. bottom of the track will start at table level to the first corner at 80mm. Track will be used both directions and will be for 1/32 scale only. Thanks again for your advise and help so far.Any feedback on this design would be appreciated. To be honest I don't know what the radius is on any of the corners. We started with a shape on paper and when we got the board we divided it into grids of 110mm. We then did the straights each side then did the corners and curves with a compass and dinner plates. Took the diameter of the plates marked that section diameter on the track and then drilled the router jig to suit each size . We routed them first then modified the straights to suit .Used the KISS princeible because in the past when I have put too much thought into a project it made it more complicated than it needed it to be.

Hi this is where I am at and would like any feed back on what you think. Would also ask those of you that have built tracks before the best way to keep the corners flat when shaping the profile .

G'day Greg, Not sure what you mean by flat corners ,but with 12mm MDF I start with temporary support every 300mm. With this lighter stuff some lengths of 19 x 45 down the straights may be a good idea then tempary props under them. For the corners,( which look very dangerous for aflat tracker like me) some radial supports and then temporary props to find the right camber.Good luck. regards digby

Thanks for the info Digby and the comment Nick. The final profile is now done and a bit of bracing left to do. Using 6mm board has made it easy to shape but there are a few disadvantages. for 1 bracing the slot at plenty of points and the amount of bracing required to make the track ridged.The attached photo is now the final shape.
