When I've made the plinth for the V8-sculpture, I just tacked it up with my good old stick welder. A deep-penetration 7016 celluloid rod did the work.
A nice sculpture needs an sleek finished stool. It took too long to finish. It was time to fire up my Tig-welder.
I consider myself a novice. Filling gaps on tube stock is a thankful for learning the essentials about Tig welding.
Lucky me, they invented the grinder. :-)
