Where are you guys getting your plastics? I've checked every hardware store in town and all I could find were 30x30 sheets at Home Depot for $180.
I was thinking of finding something around half an inch thick and drilling holes that are the diameter of my ski mounting drill bit. That way I can get jig-like vertical alignment as well. Seems like it would work, in theory...
Otherwise, has anybody used one of these? Seems like a handy tool to have; ultra portable.
