Home-made metal working tools

[Andrew Linkens <alinkens@nuera.com>]

I've been reading the book on Metal Fabrication by Ron Fournier.
An excellent book for budding panel shapers and beaters.
I'm going to make some of the home-made tools such as T-dollies, slappers,
shot-bag.

Has anybody made other simple tools that could come in handy for metal
fabrication?
eg simple metal bender that fits in a vice? a simple wheeling machine?
shot-bag?mallets?etc

thanks
Andy
