I really should be posting on the garden, which is my main preoccupation at this time. But I'll do that later. Meanwhile, I would like to tell you about my mini-furnace. I did not invent this thing; I got it straight out of the internet. (Google on "soup can furnace".)
One of the problems with doing mini-blacksmithing as I do is that it takes quite a long time to heat up the work. Maybe five minutes to red-hot. After that it goes faster. Still, it is time and gas wasted. You are heating the atmosphere as well as your work. So I built Hephaestus, the tin can furnace.
You note the propane torch at the left. This fits in a hole you drill in the can. A spreader tip works better than a pencil tip. Fire up the torch and stick it in. It is amazing. It goes from zero to orange in under a minute! That is, you stick your steel piece into the furnace and light off. One minute later start forging. Amazing! Do use vise-grips on your piece -- it gets very hot indeed.
This thing really will save time and propane. But now it's time to garden, and I have no spare time. Next post I'll get into that.
