I referred to that site in my quest to understand how best to approach the topography with this and similar techniques. I decided that I wasn’t especially keen on having my nice spline roadbed covered with textile, especially since I was going to use latex caulk to fix the sections of flextrack into place along the centreline…which, uh, was going to be covered by textile…[%-)] You get the picture.
So, I purchased a cheap hot glue gun, a bag of the dual temp sticks, and had a couple of bags of J-Cloths (real purty blue they were) and a decent pair of scissors. I held one edge of the unfolded cloths at one anchor point, say at the front of the benchwork, and draped it over the roadbed. My roadbed was never more than a foot or two from wooden beams of some sort, so this was going to work for me everywhere.
I would mark a cut line that approximated the centreline on my roadbed, a distance further if I wanted a higher hill or a lower depression, and then cut off the unwanted part for that section. Next, hot glued the facing edge on the bench, and hot glued the just-cut edge at or near the top edge of the spline roadbed. This way, the surface of the roadbed remains clear.
To get topographical relief, I merely shoved thin slats under this area and piled shopping bags filled with crumpled newspaper under the cloth, all supported by the network of slats. Everything gets re-used as I move along.
If you are still demurring a bit about which goop to use, I will strongly support Joe Fugate’s formula. If you are not happy with the surface at any point, you can break it up and start afresh, or merely carve it, or add more goop to build it up…all so simple. It does take time, though, so be prepared to do this for a week or 10, depending on how much surface you are creating, how deep, how disparate in topography, how many boo-boos you have to rectify, and so on. Also, you will have to clean t
