Cool old machinery

Enfields and Lee Enfields were left hand twist. One big advantage is that the cleaning brush doesn't unscrew! Canadian barrelmaker, Bevan King, made left hand twist barrels. Ron Smith showed me some pretty nice ten shot groups from his Schutzen rifle, with one of his LH twist barrels but I doubt the left hand twist had much to do with it. Nonetheless, I may try one (left hand, gain twist, finishing at a 15 or even 14 inch twist) just because it's different. I can probably miss just as well either way, mind you. WH
 
"Here is a pic of world War 1 Pratt & Whitney cut rifling machine"

Pretty sure S. Burkholder has one, possible two, at Hawk Hill Barrels.
 
I think ive done one left hand twist barrel in all my days, then found out why nobody else had one- everything you know about hold offs will be backwards. it was very frustrating
 
Almost always have shot Left twisters. So for me it's hard to share wind calls at matches with the right twisters. Just bucks the wind different is all. The ballistic calculators do a pretty good job of figuring it out for me.
 
Cool Old Machinery!!
WAY off topic but, had the opportunity to take some BIG bags of wool over to a place North of Sacramento that processed it into yarn and bats for quilting.
VERY BIG machines that were bought from England and were destined to the scrap yard.
Shipped over, installed into a new building just made for them. And the place was spotless!! Loved watching the machines in action.:)
New owners got a deal of a lifetime. They were going to be sold for scrap so they were able to pick them up just in time.;)
Close to 100 years old and still looked like new.
Work like a champ and turns out beautiful processed wool. :cool:
I need to go back and see if they're still working.:D

If they was in socal they would be a victim of regulations

I'm not surprised that they're still in service after all these years- but certainly there's a lot of rebuilding, right?
Bearings, gears, screws, sliding way surfaces... all wear as we know.

That's the key to making straight holes maintained the bearings and the cones and the the drill bushings the list goes on an on.
