Some non-railroad stuff I've been up to

My theory only: When you use the hard rod it has more resistance and you are probably using a higher heat. When I was building up rail ends I used 225 amps and 1/4 inch road. I had "railbuild" rod, but found that 11018 rod worked nicely too for the little traffic we had. I used the 11018 to build up point protectors too, and it really helped.
