Hi David,
I donīt have any pain in my back anymore but itīs hard, not to be able to work with metal all day.
CAD is a nice tool but i really miss the dirt and smell from forging and welding a lot

.
Iīll have to build a powerhammer and a thumbnail machine to be able to shape some metal. My Doc said : " Your shoulder has the age of 65" which isnīt funny as i am 33.
Well Iīm quite happy that i found this site.
Thank you all.
