I was wondering how the feeding or advancing mechanism works, by the weight of the fly weel?

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?

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

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 :)
