Beautiful piece of work , what size and make of lathe you using ?
a gun is just a tool how its used is dependant on the person behind the trigger .
This is why constant restrictions on legal users will have no effect on the unlawfull use of guns or knives !
Fantastic stuff, what is the reservoir?
I make the reservoirs, welding a threaded bushing inside one hemisphere for the valve, then welding the hemispheres together... I test them to 4500 psi to make sure they're ok... wall thickness is about .135"
As small as this one is 1-1/2" diameter, it's good for about a million pounds pressure!! ;>)
