[TheForge] welding heat, katana billets

Andy,
Try adjusting the propane / air mix to neutral flame and toss a few fist
sized chunks of metallurgical coke in the forge every 1/2 hour or so.The
burning coke sucks up any unburned O2 in the forge, and minimizes scaling.
Chuck
Works really well for me.
