Floor joist

Your 2x lumber is often used as floor joist or the bottom chord of a roof truss. There are span tables in construction that dictate for a given species and spacing how long you can go with x6, x8 x10 and so on. 2x16 would be a pretty good clear span. 6x6 could be posts, not just in fencing but in building construction.

can't imagine what 2 x 16 would be used for in HO scale.

nail two or more together to make a beam or header for a wide span . Can't recall if I've ever actually used a real 2X16 for anything.....DaveB

uses for scale lumber

4x4 are suitable for fence posts (6x6 overkill)

6x6, 8x8 would make great foundation posts for sheds, docks, etc. also verticals on pergolas

Use the 2x14 and 2x16 as unique loads or painted to resemble metal for bridge beams

Possibilities

2x12 = fence rails spanning 3 posts on 6' centers.

8x8 = retaining walls

2x4 = everything under the sun!

2x12 = fence rails spanning 3 posts on 6' centers.

What's with that fence? Looks like the posts are made from short scraps nailed together? The rails are more like rough (full dimension)1X6 aren't they? .DaveB

What's with that fence?

I think you are seeing shadows cast on the posts. Combined with the glimpse of the face boards on the other side makes it look like individual pieces. People build horse fence out of all sorts of lumber. Some use rough-hewn (usually oak) which could be closer to actual 1" x 6". Ours is built with 2x6 dimensional lumber and no face board. .6 CCA on the bottom rail, kiln dried on rails 2,3, &4. 4x6x8 posts, 2x6x12 rails.

Thank you all! Very

Today I took a break from working on my inglenook and started to make a buoy shed.

I though it would be a nice to have it near the lobster shack.
