Bernd -

What type and thickness of plywood are you using? I'm also interested in lightweight construction for a sectional/modular layout, but the thin plywoods available at the big-box stores seem to warp easily and have poor structural integrity, and contrary to popular forum advice, the 2 "local" lumberyards seem no better.

Richard-B uses 1/4" (6mm) birch ply, which I don't find around here. True marine plywood is nice stuff, but pretty spendy, although I guess in the big scheme of things, maybe worth it.

10" seems pretty tight - I hope you don't have long cars planned.

I may have posted it before somewhere.

Yup, know that Fast-Track has the jig. May just spring for one to give it a try.

I think the original layout design assumed #4 switches. Using FT's #6 will stretch out the length of the plan considerably - maybe that's not a problem for you.

Thanks for the curved template idea.

Log cars are usually in the 20 to 30 foot range. Class A Climax's can handle tight curves also. I'll have to lay some track on a test bed and see if 10" will work. What's minimum radius for TT? I know 18" radius is minimum for HO.

Bernd
I wouldn't recommend anything less than 12" and I think even that's pushing it. However since you're using very short cars it may not be a problem.

Minimum radius depends on the type of cars and locomotives you use. (Shay can handle this too.)
Also in the standard. You have it correct according to NMRA RP-11, where your choice of rolling stock is in "J" group, 10" radius.
http://www.nmra.org/sites/default/files ... /rp-11.pdf
Remember that it requires weight of the cars according to the standard too (they should not be too light).

According to NEM 111, and your choice of rolling stock, the minimum allowed radius would be 9.44", the recommended minimum 9.84". (which agrees nicely with NMRA's 10")

The grades will be steep. The Gum Stump and Snowshoe is also listed in "Track Planning Ideas from Model Railroader, 58 track plans from past issues". The HO railroad was built on a 1 foot x 6 foot plank with grades in the 9-10% range. Since you've chosen a length of 8 feet, considering siding length, the grades could be less.
