I want to build a trestle bridge out of wood. This will be N scale. What size wood do i need. Will 1/8 square be to large? Or should it be 1/16? This will be my first attempt at this. Thanks Paul
One-eighth is 20", one-sixteenth is 10" (duh!). Off-hand I'd go with the 1/16, for no other reason than it would give more of the "spindly" look. You might also consider using round pieces, instead of square, for part of the construction.
I "requisitioned" a package of laboratory Q-tips from work. They have the cotton on only one end of the stick, which are wood and about 3/32" diameter (or 15" in N scale) and a good 4-5" long. That's my future trestle pilings (among other things....).
