After a bit of time passed, I received my finished tube.
Beautiful workmanship. It is so pretty, I am having second thoughts about browning it.
It should throw a 36" diameter stone at least 2000 yards, as I figure it ...
OK, would you believe a golfball.
The work was done by Jamie Cartmill who, if you wish to avail yourself of her superb machining skills can be contacted at jamie_32_3@hotmail.com.
In any event, the next step is to proceed with the carriage.
BTW, since the tradition was to name cannon after women, this cannon shall be known as "Jamie" from now on.
