I know this subject has kind of been beat to death, but I have a slightly different question. I'm using a 5/8" piece of plywood with a 1/8" piece of lexan covering and I'm trying to mount the reunion stick to the panel. Without really thinking it through, we routed out the bottom 1/8" on all of the joysticks including the reunion, which works great for all of them but that one. I've read in other posts that plywood is stronger than MDF and was wondering how much further should I be able to route the hole in the bottom out? I want the best feel length wise I can have, but I don't want the wood to fall in on me. Your help is appreciated.
