If I bolt it to the wall, it would vibrate the whole wall, turning it into a large drum. There’s also the spacing problem, as the internal wall for my shop has 2x4 studs on 24” centers, while the exterior ones have 2x6s on 16 inch centers. The holes in the DC are 14 inches apart, IIRC, so there would need to be an intermediate board… after thinking about it, I decided a stand was best for my long-term sanity.
I don’t see any obvious damage to the impeller blades, and the vibration is less after shaking some wood chips out of the housing. At this point, it’s good enough, and the stand doesn’t walk around the shop when I turn it on. Next year’s plan is to have one of the motorcycles sold, and a portale roof built over the door of the shop to protect it from rain and sun, and move my low bench outside so I can work on that in the shade of the roof when the weather’s nice.
I think it was “choice” lumber because unlike Homer Depot or Lowe’s where all the tubafors are pretzels tangled together in a great heap, there were actually straight ones on top of the neatly stacked pile at my wood store.
I’m happy with the price, since I’m done. If I’d gone to either big box, I would’ve just burned down the shop rather than fixing things. I get that frustrated trying to find lumber I can actually use at the big boxes. It’s easier to cut down a tree and mill it myself.
