I am thinking of starting from scratch on my layout and use the pink foam insulation board as a base after I add 12" to the outside edge of my 4x8 tables. This will make each table 5x8 and allow me to have 28" radius curves.
How does one fasten down track and ground throw switches on foam?
How does one fasten down flex track on foam so it will not move?
Currently, everything is fastened down on ¼" plywood with tiny ¼" philips track screws. The ground throw switches and trestles use slightly larger philips screws.
One easy answer to all your question - latex caulk. It's cheap, easy to apply, safe for foam, and will hold anything to just about anything else. I used it to glue the foam to the layout, track to the foam. and foam stands I made for my ground throws. If you do a search here on latex caulk you'll find tons of threads about how to use it.
Hi: Mikey, I've used foam and cardboard strips. You can get great results from both. However, I like the strips, plaster cloth, Structolite method. I think it's faster, easy to make changes, and less messy. Just my opinion. Here's a few examples of both.
Grampy, that's a very realistic mountain you built. What did you cover the cardboard strips with? Cloth strips, paper towels, or? Thank you for posting the pictures and giving me ideas on how to build mountains. Since I am going to start from scratch on my layout, I'll plan on a mountain.
Hi Mikey: Thanks for the compliment. I covered the strips with plaster cloth. It's the same material doctors use to make splints. It's available from a variety of sources. I got some from a relative who's a doctor, AC Moore, Michael's, WS, Scenic Express, Micro Mark, etc. It's a little pricey, but I think the results are worth it. It also makes an excellent foundation for Structolite/Gypsolite base coat.
