I’ve been lurking about the archives reading up on the Ladder Roadbed, I’m considering using this approach for a stretch of my layout that goes through the garden (well a proper veggie garden). I would like to stay away from the post and stringer through this section since I want to try out this ladder roadbed and keep a vey low profile through the gardern. The roadbed will be about 18 to 26 or so inches above the final grade, but I’m struggling on just how to elevate the ladder roadbed… And this quandry is holding up construction!
The info I’ve read suggest’s not going over 24" using the TREX post’s. So I’ve looked into using galvanized chain link fencing “top rail”, but that’s just about a 1/4" to narrow for using the 2x2 spacers. I liked the ease of what HJ was doing with the 1.5" Sch. 40 PVC, but I fear that to will be too wobbly. Although my likely inaccurate measurments at the local HD found that perhaps a short ring of 1.5" PVC could be slid over the galvanized pipe to make it the proper width for the roadbed.
Basically, what I’m looking for some input on what everyone else has used and their thoughts? Mainly some thoughts on the maximum height the various methods can safely achive.
Thanks a million!
