In the JET Lathes, Mills, Saws, Etc. Forum I posted my efforts at adding a Z-Axis Powerfeed to my JET Milling Machine.
Pretty much the last step of the installation is to drill a 5mm hole through the Powerfeed shaft & Manual Crank Handle adapter and insert a Spring Pin.
I had thought I'd take the adapter off the shaft and drill the hole through it using the Milling Machine but I was concerned that doing so - without something inside the adapter to protect the threads - might cause problems.
The issue is explained in detail in the Powerfeed thread: Here's a link to the actual POST that details things with pictures and such.
As I was having issues finding a bolt that matched the internal threads of the Adapter, I was wondering if drilling through the Adapter without something in the hole would be a mistake.
