Thankyou to George Langford & Rev.Ron for adding to the info being absorbed
by this sponge-brain.

Even tho the blade I was talking about had never been zapped, with lots of
Galoots now dumping saws into zap-tanks, one of George's comments bears
repeating:

>Galoots whose saws become brittle after electrolysis
>can prevent that by baking the saws around 300 F for
>several hours immediately after the electrolysis to
>drive off the hydrogen that causes the embrittlement
>(actually, delayed cracking due to residual stress).

Sometimes things didn't work out just right at the factories, but we are
more fortunate than they were, having Ron and George and others willing to
help.

Gene  (Disston would have paid them for their help dontcha think?)  :>)
