    One of the best investments I ever made was buying a home-built building board at one of my then-local hobby shops back in the late 1970s/early 1980s. Top was laminated strips of basswood (lindenwood) with 4 2×4 stiffeners across the back-side. It’s just under 4′ long and just over 1′ wide. My only regret is not buying the 3′ one that hung around in that shop another year or so.

    I used it fairly regularly in the 80s-90s, then went into other areas of modelling and stored it in the basement of the place I lived at the time. The space was fairly stable temp-wise (maybe 45F-85F?) but could range far in humidity. When I moved from Mpls to MS in 2006, I saw the top surface had cupped slightly, a bit more than 1/32″, perhaps almost 1/16″ at the worse end.

    I cut some 2″ wide angle iron and screwed that in at each stiffener in an attempt to flatten it. It came back most of the way, but was still slightly cupped, now less than 1/32″ at the worse end.

    I spent some time last night resurfacing it… will post about that later. BUT it is now VERY flat with small areas out about a thickness of notebook paper. Gotta love it!

    My question to those that know softwoods/hardwoods better than I… should I use a finish on it? The topside did not look finished when I bought it, though examination of the bottom suggests either a thin soak in poly or similar or maybe an oil finish like on cutting boards.

    I’m thinking the latter. At least that would also offer some resistance to CA soak-in if it gets past the wax-paper/poly glue barrier.

    Thoughts?
