new alloy barrel castings are here.

Whew, these were a surprise. Didn't have much hope that the pattern would withdraw without breaking the *extremely thin* sand between the cooling fins. But it did...and here's proof!

The current build will be sleeved for 89mm pistons to yield 1120cc. These will take quite a bit of work, methinks.
