Stop in for a cup of coffee

Like some 3/4" copper tubing split into 2 halves an inch or 2 long?
I put 3 u-bolts through the flat side of a big piece of angle iron. wrapped the bar with some rubber (like a thick inner tube), u-bolts around the t-bar, tighten it up and tap the angle iron with a dead blow hammer. worked perfect. And all made from crap in the shop..
