Those are unusual pop rivits, not screws. If you can see the way to reinstall the rack then I would remove them.

I looked inside the tube and it looked like they were a tapered screw with fine threads. I’m going to remove them and put in new racks. Pop rivets to reinstall or maybe some other sort of attachment. I’ve reviewed your breakdown and new rack add, thanks for that.

The gentleman rebuilding my GE motor said he can’t get this bearing off and is getting ready to throw in the towel. Here is a pic where he is at, any suggestions?

I can't help with the bearing, I didn't replace mine, but you're already talking to the right guy about that.
Just FYI, I finished the cam parts and they work fine mounted on my Mark VII. They're not perfect but functional. If you end up eventually needing them they're yours, if not, no worries at all. It was a great learning experience for me, and I can always use them on my backup headstock.

Ya know... that was what I was thinking but he's done them before so I didn't want to insult him. I'm gonna text him to see if he got it off and ask him. thanks for the heads up.

Mike, they look beautiful and if you are willing to part with them, I'd be honored to put them on my machine:-) I'm customizing the Mark VII to fit my needs so the cam parts you made would be an incredible addition. PM me when you have time or better email me at
Mike@scskulls.com, I'm not much on keeping up on anything else and have to check my email multi times a day. Thank you!

Never got an answer on that, but he was able to remove bearing, thanks again.
