    This might work with cells which you can remove from the barrel, but on TR cells, Gundlach appears to have crimped a metal band so that the cells can not be easily removed. Thus, I don't think they can be soaked in acetone and subsequently recemmented.

    The possibility of using the small oven with the hairdryer might work with a TR cell. Has anyone tried this approach given how the Gundlach TR cells are constructed with metal bands?

    Thanks. Jon

    If anyone has any reasonable suggestions, I would welcome them. Thanks.

    Sorry Jon, I have no idea how to go about this. You could send it to Grimes, but I'd hate to think of the cost. IMHO, stopping down appears to be the best bet.
