Re: Rollcall. Blitzfike here from south central Oklahoma. I'm new to torch work, been doing stuff in the kiln for a while and am heavy into metal work as well. Great group, I stumbled on the group through a search for oxygen concentrator info, I currently have two invacare 5XL machines and a homefill compressor. I lurk much more than I post. I am an old retired guy, 100% disabled vet and am always looking to learn something new.. Blitzfike
