Hi there. New to the forum, semi-skilled woodworker. I am making a barn door for my house using 1 1/2" red oak for the frame and 7/16" oak to make the panel insert that will go in the frame.
My question is, what should I use to keep the panel in place and allow for expansion? I can't find space balls that are large enough as they seem to be mostly for cabinet doors and are .26" diameter.
Any advice would be greatly appreciated.
