Bob-stk:
The tracking seems great. There is a slight bit of L/R play. I'm not sure how much of that is the belt, and how much is the machine.
Pulleys and wheels all came from Beaumont. The wheels (drive and tracking) are crowned.
Bruce: thank you sir.
Atama: I came up with an estimate when I first posted this grinder as a skeleton (no wheels or motor). My choices are full (12') lengths for $0.50 per pound, or cut-to-length for $2 per pound. [there isn't a good surplus yard around me... just mountains of twisted metal] I went with the latter. I bought some locally and some from Speedymetals.com. Steel alone added up to $3-400. Stuff from Beaumont was $4-500. Fasteners and do-dads were $100. I mainly did this for the experience, and to spread the cost out over several months.
Andy,
my KMG will be stuck making spikes, throwers, and stars for the summer. I'm swamped with orders. Hopefully I'll be able to start making cutlery in the fall. Thanks for the compliment.
