Viper MkI

"A simplified Sten gun."

Wait, how do you make a Sten simpler?

Better watch.

Yup.  That is simple. Jeezum crow, making something Spork simple even simpler.  It's practically Foon simple.

So, you spec out the common parts and the hard machining part is a barrel and a bolt assembly... I am going through the fabrication order of operations in my head, see....

But yeah, one of the more complicated operations on that viper is all the woodworking required.  Easier now, these days, with CNC routers, tho.
