Build a homemade arc-welder. (Ya gotta love this one)

Build a Microwave Transformer Homemade Stick/Arc Welder
I had no idea making a DIY welder would be so easy to do. And, it's pretty much FREE!

So here's what you need to build a welder:
- Two beat up old microwaves
- Some 10 gauge wire
- Wire nuts

People throw out microwaves all the time, if you keep your eyes on the curbs.
Or, you can get microwaves at the local thrift store for $10 each.
Try the warehouse that processes donations - they have to pay to get rid of tons of broken ones. [More]

It just gets better from there.

High voltage, searing temps, blinding light - this has got 4th-grade science fair project written all over it!
