Who makes Artillery ??

[D B Campbell]

... your book on Greek and Roman artillary is a prime source for me as I continue this madness.

Glad it's proving useful!

The holes are 1 3/8". That was the closest forstner bit to the size of the hole I wanted. I will probably enlarge the holes a bit more as I fit in the yet-to-be-cast washers.

Aha -- so it's just a baby! I didn't notice the pen in your photo, giving an idea of scale.

As it's roughly the size of the Xanten machine (which has a Vitruvian solid "middle" stanchion, of course), I'll be interested to hear exactly how portable it is!
I have my suspicions that you'd need a back and shoulders like a barn door to effectively wield the Xanten catapult. Much more comfortable on a stand. :wink:

(The small machine from Ephyra would've been built like yours, only a bit smaller: 1¼" spring-holes. It probably was for hand-held use.)
