I had some good luck this afternoon. I went to a metal recycling center, looking for some simple steel, like 1060,1095, etc. No luck there, but I did come across several lp tanks-the 20# size. Might make a forge, somewhere down the line, says I, to myself. Then, there at my feet, were 2 12" cicular saw blades!! Got them both for about $3.00. What luck!! Built a hot, hardwood fire in the pit, put them in, turned on the leaf blower, and got them cooking, nice and red. Buried them in the ashes/coals, with more on top to burn out naturally, and slowly. This has been a VERY good day. One hour later, it starts to rain. For about 15 minutes. With "luck", they haven't cooled too quickly.
