how to make welding stand for coupons?

[snoopee]

I've been watching you tube videos lately, and seen welding school shops and in their booths they had posts with a small steel table and then adjustable arms to move to where you like. I know the generally jist of them. I would like to fab one up for myself to work on vertical welding and to try overhead. But I don't know how to make the clamping mechanism to hold the steel. And to be able to hold metal for butt welds fillets and others, I have not seen one up close, so I would like to know how they clamp the metal so i can make one of my own, any help or pictures would be great! Thanks for your time!

The ones I've seen lately just have a spring-clamp that is welded to the arm.
Some of them use "C" Clamps on the arm.

The ones we use have the table top that's adjustable in height and also another sleeve over the center pipe with a piece of pipe attached. Tack your coupons to the pipe and use the table to steady yourself for overhead practice.
