Sorry I kinda brought you folks into the middle of this rebarrel...........
Let's review...
I bought this rifle about a year ago for CAS. It is currently in 45LC.......Terrible blow-by with this cartridge. In fact, at CAS velocities and pressures, it is unusable!
My favorite cartridge is the 38-40....so a rebarrel is in order.
As you saw above, I got the rifle apart and my Green Mountain octagon barrel has arrived.
But I'd never cut Metric threads on my lathe so I needed to turn a "Practice Tenon".........It was very easy! I converted my lathe to DC drive a few years ago and being able to increase or decrease RPM with the simple turn of a knob is fantastic. Nice and slow cutting the thread, and peddle to the metal to get the carrage back to take another pass...Nice!
The test tenon came out great:
Here is what the factory barrel looked like:
The threads are actually tapered......Nasty work!
And here we are with the receiver installed:
I rented a piloted reamer with various pilots and that will be here Tuesday so the project will wait until next week to finish
Stay Tuned!
