Doing a small project for myself and given it happens so rarely Im of course over-thinking the most simiple of projects...
Have a beautiful outdoor elevated covered porch/deck. Its somewhat like a treehouse. 15' off the ground on the high side, 15x30, fully covered and screened 4 sided and below the deck. Ceiling open to the ridge with trusses. Overhangs and gutters.
Inside... 3 rigidly affixed ceiling fans (not on poles) attached to bridging between the truss bottom chord. White, exterior fans, but the blades are deteriorating.
Im planning to CNC some type of cool fan blade shapes and mask off the white fan bodies and paint the bodies a different color but really want to come up with a shape/material (thinking Walnut) to CNC new blades out of. These fans see zero rain (other than wind blown mist/fog) and zero sun other than reflected/indirect.
Ive cut fan blades for people before and balanced them on a gram scale in the shop that we use for measuring finishes. These being rigidly affixed fans Im not worried about the unbalance but of course want them close.
1/4" plain sliced walnut ply is convenient but makes me nervous even with the limited exposure and a good UV clear, but solid wood that thin also twists me up.
Jalopy mode will have me re-sawing a bunch of walnut drop material over size and plane/sand for solid. Im thinking order some longer screws and run the blades .3125 or .375 solid material, clear them and balance them to .1 gram.
