Sure was, I got some copper tubing from Lowes. 1" diameter ID. Of course you can go larger but I wouldn't suggest smaller. UNLESS of course you get the right size fr your insert. You could even get some 1/2 in Id Tubing, and drill to fit on your wood parts. The of course you could use your guts you have now. Remember, copper will tarnish and change color. So if you do that, you might wnt to consider the color of your wood to match. Once I get these 2 orders don, I plan to experiment some more. I'll keep you updated :D
