As mentioned a few posts ago, I'm trying to (finally) wrap up the flag magnetic mount.

Yesterday the Neodymium Disc Magnets I ordered arrived. These things have quite a magnetic force! They have to be separated form the stack with some thought or they will snap back together with enough force to shatter themselves.

Today I used these magnets on the hoist of the flag. Technically I think this project is complete but I may try to do something to help the magnets blend in better.
Last Friday I mentioned that I had sent an email to JET Machinery requesting information on the size of the hole required for the pinning of the Y-Axis Powerfeed Shaft. Yesterday afternoon, not having gotten a response to my email, I called JET Technical Support.
Matt took my call and he looked at the same manual I've been using as he tried to find the answer to my question. He was expressing puzzlement on the lack of information when I reminded him that JET installs these Powerfeeds on their Milling Machines.
As I mentioned this fact, I heard Matt call to someone. It turned out the Shop Manager was walking through the Tech Support area and Matt had hailed him as he did so. The manager then departed to ask his people the size of the hole. Matt said he would call me back when the Shop Manager returned with the hole size information.
About 10 minutes later Matt called. "You're gonna love this", he said. "They don't use the pin so they don't even drill a hole in the shaft."
I think I responded with something profound like, "Hmmm... but..."
Matt was just the messenger so he couldn't really enlighten me further. I told Matt I would need to go out to my shop and see if I could figure out the ramifications of NOT using a pin to lock the Extension to the Y-Axis Shaft. It was pretty much quitting time so Matt said to call back today if I needed more information and he would help me.

Today I tried to sort out how NO PIN might work. I threaded the Extension onto the Y-Axis Shaft till it bottomed out. The picture shows that the keyways don't line up.

I then used some rubber webbing to protect the shafts from my Vise-Grips as I rotated the Extension out of the Y-Axis Shaft until the keyways lined up.

With the keyways lined up, I placed the original Feather Key into its keyway and slid the Bevel Gear onto the shaft. Now I would be able to place the small Feather Key into the Extension's keyway. When I slide the Handle onto the Extension the Feather Key will lock this assembly together.
I am assuming this is what the JET folks are doing but I will call tomorrow and see if this correct.
