What a good idea this is, to plot one out at the machine shop. I've checked in with a couple of places, and they think the cost effectivenss might not be there with the CAM/Machine shop route, but the spreadsheet tells me it is after 15 props are made. I think the Zinger props are going to be the first and maybe only manufacture that I can order something comparable. I have a lot of issues, as you can see, pusher props, plus a non-standard bore hole in the hub. Thanks again.
