I have made my lines on the platform and I am ready to lay down the foam raod bed that I have in 2’ lengths. Are there any tricks to keep the foam from bucling when laying down a corner or turn? I know to split the foam down the middle and lay it 1/2 at a time- - is there anyting else I should knwo before I glue it?
Thanks
James
you’ll find that once it is split it will lay rather easy. I use thumb tacks to hold mine in place
How tight a curve are you trying to form? I’ve not had to split it all all to get it to go around what amounts to a 22"-24" radius curve. I use the 24 foot rolls as much as possible to minimize joints, especially in the middle of a curve. I mark the path, then spread a VERY THIN layer of latex caulk as an adhesive. Slowly work around the curve, pressing the roadbed into palce (the caulk is tacky, but it’s NOT a one shot only deal, you can slide it around and even pull it up to adjust as required). I use pushpins to keep things in place until the caulk dries, on curves and at seams in straight sections. On a long straight, I’ll stick a pin in here and there just so I don’t bump it out of alignment, but the caulk is generally tacky enough to hold it down. The rolls tends to curl at the ends, thus the use of pins there.

My experience is a rrinker. I have some 18" and one 15". For those I split the roadbed and trimmed at the very end.
I’ve had good luck with the WS low-temp glue gun. I also use the 24-foot rolls. You can’t glue more than a couple of feet at a time, but it sets up in a few seconds, so you can go on. No pins, etc. You can’t re-align it for more than a couple of seconds, but you can remove it easily with one of those 2 inch long xacto blades and try agin.
