OP,cut the branch in half bake it in your conventional oven.. Then when done go to Home Depot or lowes and buy some stainless steel brackets and stainless steel screws and put your branch right back together. Make sure it's stainless steel,don't want it rusting in your enclosure from the humidity of course..why didn't I think of this,9 hours ago when I replied,lol,makes all to much sense..if you wanna get fancy,get a chisel and chisel down the branch a bit so the brackets fit into the branch and then cover with some sort of non toxic wood puddy...
