Hello again fellow Darrin owners. I got an email from one of the buyers of the tach driven gear that I had reproduced. He has it installed and his tach is working fine. No noise or dancing of the needle in the instrument. That's all a plus as far as I'm concerned. I know mine worked great also. I talked to Olin at the machine shop yesterday and he says h made up 10 blanks, if you will, and has the program all set if any one wishes to give him a call requesting a new gear. If the machine he runs this on is not tied up he said he should be able to get an order turned around in about 5 days. If you wish to place an order just call WhiteHawk Machine and Tool Co. 903-450-1060 and ask for Olin Whitaker and he'll fix you right up. Thanks for your interest in this. He can and will make one of these at a time so there is no waiting period.
Richard
