Long story short, supply chain issues and long waits for contractor scheduling has found me with a 1300sqft of LL Flooring Bellawood Natural Matte Hickory, solid 3/4" hardwood flooring. The boards look really nice, and we had great success installing a similar amount of the engineered version in the basement on concrete. However, the engineered flooring had few milling/dimensional issues... while the solid it seems to be the rule. Boards are varying in widths all over, from one end to the other, board to board, bulges in the middle (near knots?).
Sorting/racking boards doesn't seem like it's going to work when ends aren't matched and there are middle bulges. Running all the boards through a router table, or running a router sled over, slimming down all boards and recreating the tongue and groove seems like a painfully long process.
A block plane seems like it will be unable to adequately straighten a (worst case) 6 ft board.
So I'm left wondering, could I get one or two 2200mm linear rails from i.e. Amazon, a router bit or two (maybe a special tongue and groove set, otherwise just square or something to recreate the microbevel) and for boards that need width-fixed... route in place. The linear rail should ensure a good straight profile (as opposed to the block plane which I think might not fare well over 6 ft of shaving).
I just don't want to return all this wood, and be at the mercy of 2-3 months minimum lead time, which could ultimately end up with similar width issues. I'd rather just make the best with what I've already got.
