Greetings Jet guys. I have a question about my Byron fan starting probe while trying to start my F 16.

The threads inside the probe are some what worn and I decided to drill a hole in the base of the the starter probe shaft and drill a hole on the base of the starter probe and use a small hardened bolt or cotter-pin to keep them from slipping. So far this works ok but can be prone to alot of slop.[:@] Any pictures or advice or even an alternate way to start these fans without using that long-ass abomination??[:'(]
Thanks for any help or criticism.
