[PSUBS-MAILIST] data cable

Sun May 31 21:36:51 EDT 2020

That's what Dan Hycroft named his sub due to all the work that went into
it. I still don't have a name and am not going to paint my sub Yellow as
that is another question that everybody asks, gonna go with a blue or
green. When I see a particular project on the plans, I formulate an idea of
how much time it will take me but as all of you know, it really doesn't
work that way and I am a fabricator. For example, hanging my drop weights
took a lot longer than I thought it would. I think my answer for when I
will have it finished will be "when it's finished"
