1972, You were smithing when smithing wasn't cool, ( as "cool" as it is now ). I think it is great you had the foresight to take the risks, you did, no doubt with some trepidation and possibly grief, over whether the expenditures, would all work out, glad they did, and continue to, with the skill and dedication, to your buisness, and craft. I love the "Christmas tree" analogy.
I'm in the refrigeration buissness, I built one of if not, the first trailor mounted refrigerant reclaiming machines, in my area, to service, grocery and other large jobs, before government regulations on venting refrigerants, hocked everything I had. Paid back many times over.
Thank You, Sir, for this and many other posts, all enjoyable and informative.
