Does anybody know how Joe F.  stabilizes the spline/sheet rock joint?  I have a technique that works for me with spline/plywood, but I am having trouble getting my head around the sheetrock/spline.

Thanks

I read the article in MRH from a couple of years ago regarding using vinyl flashing to do coved corners in backdrops. I think that is the way that I would like to go. In that article, the author mentions that he bought a 50' roll of 24" wide Duraflash vinyl product from Home Depot. Checking the HD site today, I see that they only seem to have 14" width rolls. I also Googled my heart out trying to find other sources and other manufacturers and had no luck finding any 24" or even 20" in stock.

I hope this isn't a duplicate -- it seems similar to others I have seen here but not exactly the same. I am building an around-the-walls layout in my basement. I have all of the benchwork in place (L-girder) but nothing in place for backdrops. Fortunately, (?) there is not much scenery or even roadbed in place in most places.

Today I hauled my modules out of storage; they were in there for over three years. The Extruded Polystyrene Rigid Insulation foam has shrunk a bit, but by only just under 1/8 of an inch on a piece 80 inches long. However it did not shrink in thickness. In some places the gluing of it to the hollow core door did come undone, but not down at the ends against the 3/4 inch ply. I can't recall what type of adhesive I used. I think I'll screw it down with screws in a washer and sink them flush with the foam.
