Anyone have ideas on building a carrying/storage case for a granite surface plate? Woodcraft had them on sale so I got one. We'll see if it helps with sharpening. The problem is that it's big (2x9x12) and HEAVY! I haven't weighed it but the Woodcraft guy seemed to think it was 20 lbs or so. I have a one-car garage and not a lot of room so there's really no place to leave it out. I'd want it to be sturdy of course and have a handle but also perhaps waterproof? Google doesn't seem to have plans that I can find or even an example of one I could use as a template. Any thoughts?
