I am toying with ideas for a cabinet that will hold 2 or 3 machines that will share a ball lifter. I am toying with the idea of putting a dispenser in it. Something like what is in the attached video ant 1:52 except that paying for them is unnecessary. Has any one tried something like this or have ideas about the mechanism used for them commercially. I don't expect that I will be able to buy one and will end up fabricating it from scratch bit it would be nice if I don't have to reinvent the wheel.

Thanks in advance
