I think the heat & humidity is getting to me today. I am trying to explore using Grizzly rods for setup for threading for suppressors.
So todays trial failure had the action in the 4 jaw, with thick brass pads. Dialed in roughly the OD while using a live center. I then put on the steady rest and a home made action truing jig.
I adjusted the steady rest while using an indicator so as to not push to much one way or the other on the jig. Inserting the Grizzly rod into the barrel a few inches and then adjust the back set of screws on the jig. Move the rod to the crown, try to adjust the front and just can't dial it in. I start to get close then on spot is always out by a 5-10 thousandths.
It also seems like that is a bit of deflection in the steady rest to jig fitment. But if I run the screws down any on the steady, there is too much friction.
So what can I improve upon besides the lathe? When I through this barrel action between centers I was less than impressed by the amount of runout, so I thought this would be a good time to learn a new method. The host rifle is a Savage .223 bolt if it matters.
Thanks
