a small dab’ll do ya. And don’t get any on your fingertips, it is hot! The low temp stuff is about 170 degrees, the hi-temp is about 375. The low-temp stuff is great for working with foam, ie. attaching tunnel portals, plaster walls, rock castings, trees and oh yeah, Caboose ground throws, (if you don’t get it positioned right the first time and you do have to be deliberate and quick, (you’ve got about 5 seconds), just pull it up, clean off as much glue as you can and try again).
It’s the "CA " for scenery. When using it to attach foam to foam keep the hot glue away from edges that you intend to carve, the glue doesn’t carve well.
Caboose Industries uses Delrin in the manufacture of their ground throws and Delrin don’t glue . . . . . . . . . . or caulk either, for that matter . . . . . . . . . . with what you probably got available. This is a job for: (TA-TA-TA-TA-TA TA-A-A-A-A-A-A . . . . . . . . . . that’s the sound of trumpets heralding the arrival of Superman . . . . . er, ah . . . . . Profound Information) track nails or screws.
Hey, Rich, thanks for asking. Sorry I didn’t report back sooner; I’ve been battling a three-week cold that seems to just keep getting worse.
Anyway … good news! I re-attached my two test ground throws nearly a week ago, and they seem to be holding up perfectly. As I think I mentioned earlier, I simply slathered on the caulk (making sure not to foul any moving parts) so that when I pressed the ground throw stand into place, some caulk welled up through the spike holes. I also used a needle to spread a bit more caulk around the exterior of the stand. And I held it in place with T-pins sunk into the foam alongside it, rather than through the spike holes.
I have 8 more ground throws (and two turnouts) to install on this section in the next week or so. Then, by the end of the month, I’ll be taking this section down and transporting it from my detached garage into the basement of my home (it’s on a hollow-core door). That could perhaps give me some indication of how well this method holds up.
Incidentally, I think I’m going to take an X-acto knife and carve a few lines into the bottom of these next ground throws, with the thought the irregular surface might improve adhesion.
Again, thanks for asking. If anything develops that leads me to believe this isn’t a viable approach, I’ll post again and try to save others from making the same mistake.
