The way I see it, in order to build nice straight wings and fuses one needs a good flat working surface.

I've heard of guys using hollow core doors and such and wanted to see what you guys use.

I won't tell you that I just finished building the wing panels of a Sig Astro Hog and ruined them by building on surface I mistakenly thought was flat. Boy if you ever want to test the flatness of a surface and find every little hickup, valley and irregularity, build on what I used: a 4 foot Great Planes building board thrown on top of my ancient workbench.

I'm ordering a wing kit today.
