Heavy duty meat cleaver I forged, its not cut from plate, it will cut virtually anything and hold an edge, I spent the afternoon splitting fire wood with it and cut an old tire off a rim with it.
I belt buckel I made for a friend, took a mold of one of those shit metal ones and cast it in silicon bronze and put his name on the top, he wears it every day
Those cracks are in a place that you could repair them, as they are seem to be with in the frost plug holes and and that fitting, a block seal would take care of them or you could weld them with a nickel rod, they cant really spread
It was too expensive to get some channels folded up for the motorcycle trailer so $20 in reinforcing steel and I made some, was a ridiculous amount of welding but I only have $42 invested in the trailer.
