Welding a Crosscut Saw

While cutting firewood I broke my "hard luck" saw. This saw was reconditioned from a junker saw and I posted the process at:
http://www.bchw.org/Tech%20tips/sharpening/Saw%20Reconditioning.htm

It was not a big surprise when the saw broke because it is a very hard and brittle saw that was already cracked about 1/3 of the way access the blade where it broke. The was was about 5ft long and nearly 18" broke off. After it broke I continued to cut and with the size of log I was cutting it worked fine. However, just for the fun of it I decided to weld the broken section back on.

I took a welding class and it was super similar to things they do in these photos. We trimmed and cut and welding things together. Some of the guys got really creative and started to create small robot figurines. http://www.greatlakesweldingandfab.com
