I need to make a couple of lens holders for one of my cameras. What I'm running into is that the thickness of the wood I need has to be relatively precise, at least by wood standards. More like metal clearances.
I found this out the hard way when I bought some quarter inch plywood for this purpose. I eyeballed it compared to what I had, but it's off by about .050, and that keeps it from fitting in the camera.
So I'm guessing that I need to plane this down by about .050, but it's got to be perfectly even, or pretty close to it, all the way across the surface. Metal milling is made for that kind of precision, but how in the world can it accomplish it on wood?
