installing solid body rivets

[Vin-tin]

I've been working on my mid-'30 closed cab pickup cab off and on now for the last couple of years. The cab was completely taken apart when I bought it. Last winter I finally got 90% of the cab assembled using small machine screws and nuts to hold everything temporarily in alignment.

My question is, what method and tools do you guys use to install the solid body rivets?
Do I need to go out and buy expensive rivet tools or is there a cheap, old school approach?
