Long story short, I broke my joint piece for my oil rig. Well, I ended up taking a broken pipe I had, refining a small part of the mouthpiece to size, used my glass nail piece and a small spring I had lying around(so the bottom of the nail piece isn't RIGHT on the mouthpiece and blocks the air) and made a custom dab bowl. It looks sharper than it actually is, later im going to go ahead and grind it down. Works like a charm!, it's pretty sturdy and all. Anyone else have any other homemade / hybrid rigs??
