Having enough clamps to put even pressure on parts being cemented together is always an issue for me. My wife had bought these miniature clothespins at a craft store and then didn't use them for the intended purpose. She was about to donate them to the local resale shop, but I said "Wait a minute. Those look useful." Turns out they really are. Also, I think I may have posted previously about working on a pizza pan. Also very cheap, contains messes and keeps small parts from going astray.
