All MetalShaping - Found my way here when I should be working

Hi folks, another Aussie here, Rodney from Melbourne.
Short version..I ended up here chasing info/clues about thumbnail dies.
Longer version... I'm a qualified panel beater, now working for myself doing all things rust and custom metal related in a small shop in South eastern Melbourne. Long term customer has me working on his LH Torana sedan involving quite a bit of subtle custom mods to suit a big hp motor combo. I make just about everything myself including my own power hammer that is almost complete. Mostly looking for ideas and ways to fit tools and other stuff.

Couple of videos of my hammer if you are interested. Thanks.
