OK, Need some help here. Awhile ago I saw somewhere deep in a thread a short how to on properly lining up, marking and drilling a prop for a DA-50 (I have searched for the last 2 days and cannot find it). I am not to the point of drilling yet but it will not be long before I have to drill my prop for my new Yak and I want to do it right the first time.

The post referred to where to line up the ignition to ensure safe starting of the engine, then marking the shaft and I do not remember anything else. I am not sure who the author was but I am hoping it was in this forum. Regardless of that any pointers would be greatly appreciated.

I know I should have saved it when I saw it but I was not thinking clearly at that time. Thanks in advance for help.

John
