So to start off, I'm a bit of a newbie at all this. I've gotten some pretty good ideas so far
First I'm going to head to Lowes and buy 3/4 inch plywood. Probably the flooring kind. I'll have them cut it to 35 by 35 inches. Then I'll sand it down a bit so it's nice and smooth and splinter-free. For the siding of the enclosure, should I use the same wood or something thinner? Should it be the exact height of the pad (1/2 inch) or slightly smaller? Then I was gonna drill 4 screws into each side to keep the sides on. Inside the enclosure, maybe put a few pieces of velcro down to keep the pad steady in the enclosure. I was also thinking of putting something on the bottom of the enclosure to keep it gripped to the carpet. Perhaps grip tape or something rubber?
Thanks for any advice.
