Quote:hen I remembered I bought a piece of steel pipe as a lever, when 3 years ago I was trying to rebuild my pool pump,

During my working career, I was a industrial hydraulic mechanic, short term: Pipefitter. Removing unions from 3" steam pipe that had been joined for some 40 years always a problem. The bashing with a 10# sledge the the application of the "Trimo" 4' pipe wench, didn't always succeed. So, a 6' section of pipe was applied to the Trimo, affectionately called a "gunner"... Always had to have a helper, the Trimo weighed in at 30# with the gunner something like 50#'s. Helper would support the assembly and I would jump on the gunner...

Most of the early speakers were glued with celluliod cement, it will soften and release with repeated application of acetone. Then the cone, spider and voice coil can be removed as an assembly.
