Thanks Neil, some very interesting links again. After having googled a bit further on the subject it doesn´t seem that impossible to set up a small foundry in the backyard. Would certainly make a lot of fun, I think. Rather busy at the moment, but will post pictures of the defects a.s.a.p.
Thanks to you too, Steve, for the supporting words. I haven´t made any comments in your thread (yet), but I really admire the detailing on your walking dragline, so I take words coming from you as a big compliment.
