The demand and usefulness of a skill is often made in either self satisfaction or public demand. If You like making things, that's good. If You can find and fill a niche and make money at it then- bonus points.
I don't have much experience so take it for what it's worth, the only common denominator I see in Your posts that might need to change is..............quit watching the Lions. You already know they are going to lose anyway. Spend the time taking Your frustrations out easily on red hot steel. Practice wins.
I have seen a factory maintenance dept. sharpen their bits. The welder they had was skilled with a cutting torch and cut a tiny sliver off each facet of the point, looked good, no further annealing done.
I cleaned out a welding shop and have 20-50 lb boxes, yep 1000 lbs not counting what I have bought. Some that is unmarked is hardface rod, wonder what it is?
They talked about finishing iron with walnut hulls and other natural things, thought there might be some interest here. Just forgot about posting to a commercial site.
The subject of a finish for iron projects comes up here now and then. Thought this might help. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx commercial links removed
