Bobby,
Sorry about the lack of posts and attention on here. I have been dealing with a never ending run of deaths of family and friends this year. The last 12 months have been horrible. Grandpa just passed, and my mentor in engineering will only make it another month or two.
I havn't been in the shop much at all for several months. I love the Grinder and will be picking up another one with a 1.5 hp motor shortly. I have a couple of projects for folks on here that are close to wrapped up and frankly overdue.
The guy who builds the grinders name is Jose Navarro, he lives in Gresham, Oregon. You can look up his number from there. I will dig into my records and emails on here and send a pm in the next day or two.
