Recent Tab Power Chamber Rebuild

Post by b2major9th »

Mostly, these were just the victim of extreme wear, but also needed the baffle plates removed and rusted out pop rivets replaced for reliable function.

Not being the owner of a tabbed back Leslie, could you explain what function the pop rivets perform, and why they were installed in the first place, presumably instead of a machine screw?
Thanks!

The pop rivets are a cheap and quick way to re-install the baffle plate - but not the best way. Standard machine screws are not good because the head sticks up too high and can foul the back of the diaphragm disk in operation

What was used originally by Leslie to hold the plate?
