I have been pondering this for quite a while, I have heard that with woodland scenics Mod-U-Rail & other components, using track nails often doesn't work, and the tension of flex track (which I plan on using) can actually move the nail and distort the track & foam. But I have also heard that in humid conditions woodland scenics glue can cure incorrectly and also cause distortions. But I have come up with an Idea and I need you guys to help me generate a go or no-go opinion. I have gotten the Idea of using both. As in, say I am using a 2" riser, I'll trim 1/4" off of that, and cut a piece of 1/4" plywood to the same dimensions/radius ect., glue that on top of the riser so I still have my 2" elevation, glue track-bed on top of that, lay down the glue, lay the track, and nail it into place as a redundancy just to be sure that track doesn't bend over time, using the plywood to provide a rigid structure for the nails. Could something go wrong that my 13 year old brain isn't seeing? Thanks in advance!
