I'm in the process of rebuilding a Ruckstell and have come upon loose rivets holding the outer casting onto the right axle tube. This is a large drum rear.
What have you guys done to back up the rivet inside of the tube while re-peening the rivet head? How were these made when new?
If the rivets are loose, they must be removed and new ones installed. Rock solid bucking is the key to successful riveting. The horn of a large blacksmith anvil would probably work well for your particular job. Install the rivet, then heat the shank red hot with a pencil flame in a torch. You don't want to heat the axle tube. Squash (expand) the shank by hitting it SQUARELY with a heavy ball pein hammer, then re-heat the end and form the head with a heading tool in an air hammer.
R.V. has it 100% correct.
Do you by chance know the dimensions of these rivets?
I had made a heading bit for my air hammer a few years ago. Now that you mention the anvil, I can envision exactly what to do. Any large shaft welded to a heavy plate and clamped to the welding bench would do, as long as it fits in past the other heads. Now, I just need to get the rivets. McMaster? Actually, these may be the same as would be used to fasten the blades to a sickle bar hay mower. I may just have them. That's what I made the heading bit for.
A source for rivets I have used back in 2008 was:

Best of luck,
Dom, thank you for that contact. I just reached out to them.
