I can’t figure out the rear drum on my project. I have attached a photo. It has no fins so I suspect it is E2/463 rather than B4/463 as I think it should be. The hub is the correct version with a smaller flange with oval spoke holes on the plain side. As you can see it has 6 holes, 3 nuts and 3 rivets. I can find no references to this arrangement so I am thinking that someone has drilled the drum to enable rivets to be placed in the hub holes where the dowels normally go. Before I drill the rivets out can anyone please let me know if I am completely wrong! Is this actually a known configuration that I am not aware of?
......look just like yours. I don't believe they are rivets. Try to remove the drum before drilling. With a bit of lubricant and persuasion, it should come off.
You were 100% right Mike. Thanks for taking the time to help. I feel like an idiot of course, but pride before a fall!
