>>886619>>886691Ok, hardwood flooring is a decent source if you need a lot, but there are cheaper sources.
A big percentage of pallets are made of oak, which is why they're so commonly used for projects. You'll need to dissasemble and plane, but good source for small oak boards if you are careful to pick pallets that were probably not treated with nasty stuff.
Second is other shipping lumber.
>>886630 has the steel studs shipped in and the strap holders on the bottom are some sort of hardwood (definitely not pine based on the density and wood grain, but not sure exactly what. Probably oak.)
I've also heard that if you're nice at the lumberyard they'll let you take the hardwood shipping lumber (because if a lumberyard has tons of maple boards, they use the uglier ones to ship the rest on instead of paying for pine or whatever).
Next is furniture. if you look, you can find cherry and walnut and oak tables and desks (big slabs), and occasionally mahogany. You'll have to pick through to learn to identify particleboard with a veneer or plywood tops, but even cheap tables often have hardwood legs.
If you'd rather have a lot and are willing to spend a little money, ask your local goodwill or salvation army where they send furniture that doesn't sell. They usually send it to a salvage dealer, and you can pick through all the hardwood tables with dents and scratches for a few dollars.
