We just replaced the closet doors in our master bedroom with 6-panel doors that match all of the hinged doors in the house. The old doors are hollow core doors. I'm planning to keep them around as temporary work tables or ??? I was thinking that instead of buying sawhorses to put them on, it might be better to make some kind of knockdown sawhorses. Ideally something that I could make from plywood. Has anyone used a design that worked well for them? I'd rather go with something that someone's had good luck with than just picking one off the net.
