The start of this video shows the bolt  lug deflection off of the of the reciever  lug. This when seen, will open your eyes to the next step in accurizing. Also it makes it easy to  understand and explain to your customers.

Next the use of the action bolt bore reamer/mandrel is shown and demonstrated on an action that is being blue printed and double sleeves on the bolt.

Then  the nitty gritty of sleeving a bolt body. All setups for machining are shown from start to finish on the bolt. A double sleeve  is what is installed, and how to setup so the firing pin hole is held dead center of the chamber.

Sleeving bolts for actions that are not having the bolt bore raceway
rebored is explained. Also what and why when sleeving a competition action, veers that elk rifle. The tape ran out and tape two was made to properly finish up the small details that only through time, money,and experience I have learned. THIS VIDEO IS CUTTING TECHNOLOGY.

RECOIL LUG LATHE JIG

After  single point re-cutting the action threads, the barrel tenon threads will be a larger diameter. Meaning the I.D. hole in the lug will have to be opened up to give appropriate clearance. In the past smiths set the lug up on a mill, dialed it in and machined for clearance. Accurate but very time consuming for an operation that makes you no money. Just part of the job.

This jig works in a 3 jaw chuck. It takes about 5 minutes to clamp the jig in a 3 jaw, clamp and center lug with the tailstock, and then bore diameter. I use a standard oversize diameter for all my rebarrel  tenons in the lug area so when I setup to do one, I do every lug in the shop at that time.
