Okay, so I'm intrigued by this whole bandbell bar thingy. Of course, being the DIYer, I'm not going to spend $300 on one. Here is my design in fiberglass tubing. The pieces will be bonded together with 3M 5200 adhesive for a permanent setup. Should be pretty strong with 1.5" outer tube and 1.25" tube inside. Again, all glued together with a really good quality adhesive.
If you're wondering what the heck these are for, check out the video on Rogue's page:
Now if I could just somehow get all healed up maybe I can start using all this stuff!!!
