In 2008 I asked Cruzin Bob Scott to build a modular table top four lane 1/24th scale routed track of 4' X 8' sections. We started out with three sections, the "Keyhole", on one end which is a hairpin with a raised "S" on one side, a straight section and a very banked section. He looked at my napkin drawing and told me he couldn't do a four lane on that size table but I asked him to try and it took some effort but he pulled off what has proven to be a great track. And we didn't stop there. Later I asked him to build two more sections, one with a "pinch" or chicane one one side and another straight section. All was good but I could only run the two ends with the garage closed and That wasn't very interesting. So in 2015 I got wild and I asked him to turn that last straight into a donut that would turn things ninety degrees and again he said he couldn't... I love it when he's wrong! So I did another napkin pic and off he went to do his magic. Well it worked like I told him it would and we've been running it every chance we get... until the Wuhan Flu hit. You see to store it in my garage I have to stand the nearly 300 lbs. sucker vertically up against a wall and with only those cheap folding table legs it was a bear for me to set it up by myself. I could do it, I mean I'm old but I can still get down and up off the floor. I had to spin it away from the wall, open and latch the legs at the top, lower that end to the floor, then with one hand pick up the "heavy end and balance it on a saw horse so I could crawl under and latch the other leg. Dangerous at best and not good for my right shoulder. A while back my friend Steve Hill told me about a leg system he saw online and sent me a link to it and what a difference it made. It's not a new idea and the guys who I've seen post it trace it back to shipbuilders so I guess it's shareable by now. Depending on your design you'll need some hinges and some gate hasps. Here are some pics.
First remove this wobbly old legs but measure the distance from where they mount to the track to the bottom of the legs (not the wheels).
My radius is 29-1/4" yours may vary. I cut it with my Rotozip (Mother of all Dremels). I left the other end back 8" from the end so I could attach the track sections.
