 Hi Paul 
I am also building a K350 I agree with Frank when I started I could weld 
but not the kind of welding demanded by the construction of a pressure vessel I 
had a mig machine but it was not strong enough so with the advice of the psubs 
group I went the stick route I obtained an old 400amp machine and only 
use E7018 and 316L  4mm rods for the fine work I use Tig I also 
purchased Welding Secrets Revealed CD-ROM through one of the members sites it 
helped stacks 
In the beginning I used the grinder allot grinding out bad welds but now I 
would not let anyone regardless of there qualifications weld any part of my sub 
not only that but I purchased a lathe and have learnt so much and love every 
moment of manufacturing the different componenants  
I found building my sub has taught me discipline and that's the key I 
believe to the whole process. 
All the best
