Hi Jon & Brian,
There are some pretty big cast tubes that are done
as a standard line
that I've seen advertised by Chinese manufacturers.
Might be an inexpensive way of doing
the conning tower in the future
I came across this supplier that advertises
500mm diameter & up to 40mm thick
However the advert is a bit confusing.
4" is a huge thickness. I could imagine forming it
would be fun- days in the oven. They'd have to cut the
angles of the mating surfaces first wouldn't they,
then clamp & glue it round a form wich they could remove
some how.
Brian you might be able to control your boat from
up in the conning tower. Pay a student to interface a
remote play station controller with your motor
controls. There is heaps on the net showing how it's done &
ready made circuit boards to help with
this.
Alan
