Great stuff.
I was of woodwork background myself (dad a woodturner) and so had a woodwork mentality to our tank project as well. But over the past four years I have learnt a huge amount from Dr G about welding, metal prep, etc., and now love the metalwork too.
I guess you could call me bi-material.
Keep up the good work, I am jealous of your shed too, but the Lady Hedgash and I have just put a deposit on 50 hectares (138acres) of land west of Melbourne with a couple of sheds already and NO NEIGHBOURS for a least a kilometre so I can angle grind all day long and store as much junk as I like...
