[PSUBS-MAILIST] PLC input question

Thu Nov 3 19:08:58 EDT 2016

Hi Cliff,
Great work - I could not think of a more exciting high school project than
building a submarine!!  That said, I'm amazing someone hasn't shut it down
for being "too dangerous".

I haven't looked at the K-boat plans for a while, but I also recall some
reading between the lines - I had considered converting them to CAD to make
for a starting point for alterations but never got to around it.  Perhaps
you would considering making them available (with a disclaimer, etc.) for
distribution/sale with the K-boat plans on the PSUBS website.

Cheers,
Steve
