Re: Leaky cell

Dear Songpon,

In addition to Virgil's comments: Examine all centrepieces for
scratches, either between the channels or from the channels to the
outside. Even small scratches will result in leaks. The scratches can be
removed by lapping the centrepiece in forward and reverse figure eight
motion over a smooth flat piece of glass using the fines from brass or
silver rubbing paste (in Australia, imaginatively called Brasso and
Silvo). Be patient and expect your arms to get sore.

Yours, Michael
