How would you clamp this?
I'm building a display case that basically consists of a base, four posts and a top. Glass will fit into slots in the posts. I've made the posts with round tenons on one end; it will fit into a round hole in the base. Sounds simple, but I've done some dry clamping runs and the clamp seems to make the post want to go out of square from the base. It just seems like the weight of the clamp is enough to make the post go wonky. Not much, but I need it to come up straight to accommodate the glass. Any ideas for how to provide enough clamping pressure to make everything stays put while the glue dries without making it go out of square??
