how do you mount a variac?

I am in the process of building my control box for my coil and I can't 
figure out how to mount the coil on to my box. I have seen people's variacs 
that are just hanging there, but their are no bolts on the other side... 
Also, on a slightly random note, when you turn off the power to your caps, 
how much heat do the bleeder resistors give off?
Thanks
