I'm really looking forward to seeing what you do with these. All that oak sounds like it's going to be beautiful!

I'm going to make some budget diffusers in MDF and pressboard, but I'm thinking about making a set of really nice ones out of Poplar or some other solid wood for the front of the room. Something I can stain and have looking like furniture.

One thing I can recommend, if you can, have them stained and clear coated before assembly unless you have a spray gun. The first set of diffusers I did took days to stain by brush. I kept finding all these spots I missed when it was dry and had to touch up...and touch up, and touch up...I never got around to do clear coating them because of that.

The second set I used an automotive spray gun and had the warm cherry stain done in about two hours, one good coat and done!

Solid oak strips?

Where from?

I'd hate to have to plane all that down myself!

Yeah, bandsaw is too rough for ripping these down to size. You'd still have a lot of waste and still have to thickness plane and/or thickness sand on a drum sander (a tool still on my wish list). So if you can find a good source for already thicknessed hardwoods, that would be awesome.

Add guns, guitars, home theater, and photography to my list of hobbies and...well, my hobbies go in cycles so I can afford them.
