Flying Saucer floor timber

Good morning,

I have noticed that some folks use 3/4 plywood, as the plan states, and some use solid wood for the floor timber on frame
5 1/2 for the Flying Saucer. I wondering what the reasoning is for each method?

Thanks,
Flash

I would suspect it has everything to do with economics and esthetics more than anything else. I would be reluctant to put in a 'solid' floor, I would worry about trapping moisture below the floor, slats lets things air out.

Plywood is better for the floor timber in framing because the grain is running many directions in the laminated plies. Solid wood may have a grain pattern that is not as strongs as plywood.

Given that you've already cut the timber I'd keep with it if it is up to the task. Ply will spread loads better then solid timber, but only has half the longitudinal strength as only half the grain runs in that direction.
