Nice job. It's great to see old tools restored to good working order. I have exactly the same drill and need to do a similar job on it. However, I have a question - at 5:15 you fit some small part (ball bearing?) followed by a bolt (but not just a regular bolt from what I could make out) into the hole below the flywheel - these parts are missing in mine. I've slowed down the video and watched it a dozen times but I still can't quite make out exactly what is going on there or how to replicate the missing parts. If you could shed any light on it, that would be great, thank you! :)
Hi, I'm not 100% sure, at ~2:33 you can see a ball bearing which sits against the course thread. Yes, I think part of it might be the weight but there's a thread on the 'Z' and an amount of down wards force. Maybe the weight/bearing friction might balance it so it doesn't plunge at a constant rate when there's resistance. It works well on wood, steel I have to back it regularly... part of that might be my bits though?
Mine gets stuck sometimes, I can free it by holding the top disk while turning the handle? Oh, free of the thumb screw/bolt friction setting at the top first :)

Nice job on the restoration
Thanks )
Thanks
No problem
I was wondering how the feeding or advancing mechanism works, by the weight of the fly weel?

I've got one of these I'm restoring, but it doesn't go up and down by itself
