SNS 296: Custom Square Drive Tool, Heat Treating

I build a custom tool for a customer, consisting of different sized square drives used for opening hatches on train box cars. We'll machine it and do a heat treatment using the Hot Shot 360. My Amazon store where I'm adding many of the tools and products I use in my own shop. Amazon.com/shop/abom79 Paypal Channel Donation: https://www.paypal.com/cgi-bin/webscr...
