Bob Mears:
"How many of you will be interested in a formost type shutoff, in a complete kit, for $30.00 each, or $100.00 for 4? I've got this down to a very simple kit to install in about 10 minutes. I'm having the bottom piece laser cut out of aluminum. I must buy 100 to make it worthwhile. The last thing I need is 100 shutoffs for myself. I've changed it some since the first prototype that is in the photos section. Much simpler now. I've actually hand built 10 for me and they're working great. So I dont even need any now, but I will make the investment if the demand is there."
