Home-made stud and/or spot welders

[Moderator]

John Fenner showed us his home-made stud welding solution in a Project Journal entry some time back:
http://forum.britishv8.org/read.php?13,15518   John's solution used a 12V battery, battery cables, and a Ford-style starter solenoid. To grip and pull the installed studs, he used parts from a gutted pneumatic pop-riveter to which he attached a slide-hammer.

Have you tried something like this? Thought about it maybe? Please share your tips and ideas.

I'm also interested to hear your thoughts about building a battery-powered spot welder.
