I have an old 3'x5' dining table sitting in the garage. I think it would be perfect to go in our den as a large coffee table so my wife can do her huge 3000 piece puzzles up there.
The legs are detachable, so it should be easy to just chop off the bottoms to get to coffee table height. What I'd really like to do is have the height be adjustable so it can go between coffee table, mid-height for board games etc in front of a shortish couch, and up to dining table height.
I know a thing or two about metal work, but almost nothing about woodwork, so I'm hoping for something fairly simple. I don't need the height adjustment to be continuous or even particularly easy. My thought was to:
- chop off the bottom ~6" of each leg and then cut that in half.
- drill a hole in the ends of each piece
- attach the pieces together with threaded rod
Then adjusting the table height would involve screwing the bottom sections on or off one at a time. As a bonus I should be able to use that to level the top too.
- Is this a sensible way to do things? The legs are straight vertical, so there shouldn't really be any horizontal forces on anything.
- Can I just use a drill press for the center holes, or do I need to remind myself how to use a lathe?
- Any rule of thumb for picking the rod (material, thickness, threading)
- What's the best way to attach the rod? I was thinking to tap the wood itself, then glue the rod into the bottom pieces. Would something like a nut make more sense? If so, how do I attach the nut? (epoxy?)
- Is there a completely different better way to do this?
