FILENAMES: TIG_topview.jpg TIG_rear1.jpg TIG_open.jpg TIG_closed.jpg TIG_rear.jpg DESCRIPTION: These are pictures of a bracket setup for holding compressed gas bottles. Posted by Rob gradstdnt . The following description was provided: ================================================================= The following TIG_*.jpg files show a simple bracket I made to secure my 80 cf argon bottle to the back of my Miller Dynasty Tigrunner. The cart is designed to take the larger bottle secured with a chain and has no provision for my customer owned bottle. TIG_rear.jpg Shows how an 80 CF argon bottle stacks up on the tigrunner cart. TIG_topview.jpg The bracket wraps around the argon bottle and secures it to the cart using an existing bolt. You can see some rubber padding I put between the bracket a the bottle for grip. The bottle doesn't jiggle, rattle or move at all. I can't even rotate the bottle to see the flowmeter without undoing the bracket. This is much much more secure than the chain draped around the bottle method. You can see that without this bracket, the cart has no provision for securing a bottle of this size. TIG_rear1.jpg You get a another look at how the bracket fastens onto the argon bottle and secures to the cart. A slot cut in the bottom of the small rear bracket fits into a slot cut on the top of the larger front bracket. I cut the slots so that I have to apply a slight pressure to get them to align. This applies enough preload, spring force, to keep the bottle from moving the slightest. TIG_open.jpg Shows how the slots are cut. The preload is relieved here, thus the slots don't quite align. By pushing forward and down, the braket locks itself into place. TIG_closed.jpg Shows the closed position from the same viewpoint. There is no reason why this design couldn't be adjusted to accomodate different sized bottles. By putting several slots along the sides, many different sized bottles can be secured.
