Re: another pole pig query
to: Tristan
Go to a large repair shop for electric welders --- you might be able to
pick up the parts you need for the reactor from the repair shop, perhaps an
old physically damaged welder -- fell off the truck type -- for only a few
$$$$. It's worth a try. With some TC pictures, a good story line, and
some diplomacy they might just donate an old system to your cause.
