I have 2 that I am in process of depotting...
I had alot of luck with removing the case, freezeing and then cracking the
asphalt off with a hammer and chisel. Makes a big mess as bits crack off and
fly around but - works like a charm. The asphalt gets very brittle when
left in a freezer overnight.
The only thing I have left to do is getting the last bits off...the stuff
stuck in around close to the windings and in the core. It has been said that
soaking in gasoline or some other similar solvent should do the job nicely
but I havn't gotten around to finding a suitable container and location for
soaking it in such volitile substances.
