Trued the action yesterday. It was the best Savage action I've had in the lathe so far. From the factory the receiver face was only .002" out of true and cleaned up with one light cut. I've had them be as much as .011" out of true.
I indicated in and polished the chamber. While the breech end was trued in the headstock I threaded the barrel nut on it, checked it and found it to be dead nuts so I left it alone.
I also recut the crown. Typical "before" picture of crown:
Typical "after" picture of crown:
This was cut using a home ground and freshly honed HSS bit with thread cutting oil at about 250 rpm. The first try was dry at much higher speed with a carbide bit but it didn't make as crisp an edge as I wanted. My dad taught me to grind my own bits when I was 10 years old so that wasn't a problem.
The throat in this rifle looks pretty good. Typical picture of throat after 30 rounds:
It's completely symmetrical around the throat - which is less common than one might think in factory rifles. All the reamer scratches which would be horizontal in this picture are gone which indicates to me the throat is completely broken in for practical purposes. So far it has had what ever the factory shot through it, completely cleaned, 4 rounds with complete cleaning between each, 2 rounds with complete cleaning, plus those from the recent range session for a total of 30+what ever the factory shot through it. It was obviously cleaned after the range session.
I will keep the stock front pillar but I'll rough up the hole and glue it in place with epoxy. I need to make a new rear pillar. I'll do that today.
Then I'm on hold till the recoil lug and go/no-go gages get here.
FWIW: This is the home made rig I used with the Hawkeye bore scope to take the pictures:
The Camera Adaptor:
And the sled for the camera and rack to hold the barrel. The camera is so heavy I didn't want to take a chance on having it slip and destroy the very fragile borescope.
Am I having fun? Oh my yes.
