Weight 7.2 lbs
Material: Copper bars, steel center
Needed by Sept 2021 or earlier if possible.

Just the outside diameter. And just the solid part of the copper bars. There is a small slotted area at the top of each bar that doesn't need to be skimmed.

A bit of advice. You probably should just take them to a local electric motor repair shop, they do that work all the time and are experts at it. Copper is soft and abrasive, someone not familiar working with it could make a mess of your parts.
