Preface, I have not worked with a planer before.
I have a curved piece of wood which was created by laminating three 1/4" oak boards over a form. The curve looks good but I would like to clean up the edge. I can do this with a sander of course, but was wondering if I could pass it through a thickness planer. Basically place the piece on its side (its about 3" wide) and pass it through.
Is this "safe" to do on a planer? Should I pass the form through too to provide support?
