I've got some sample pieces of 1/4" oak plywood, finished on one side but it measures 3/16", not 1/4". If I router out a 1/4" slot in the rails and stiles, won't that be too much looseness for the panel?
Also, the 1/4" plywood seems awful flimsy. Do you think it's thick enough for the middle insert?
Are there any other ideas? Is there a little bit thicker panel than 1/4" or do I have to go all the way to 1/2"?
Another question...Would it be a better idea to use 1/2" oak plywood (Is there such a thing as 3/8") and rabbet out the back of the rails and stiles instead of cutting a groove? I suspect that I would simply glue the panel into the back of the door but I doubt the finished look would be as good as sliding it into a groove, right?
These sound like dumb questions but I'd rather get it figured out now instead of finding out a week after the project is completed.
Thanks in advance!
