I want to machine an adapter that screws onto a metric m14 barrel that has M15x0.75 pitch external threads, to convert to 5/8 for more standard muzzle brakes. Concentricity and alignment are going to be critical. Here is my tentative plan:
1. Drill and tap for the M15x0.75 and screw adapter onto barrel;
2. insert a range rod into the barrel through the adapter and true the barrel up with spiders at each end just like chambering through the headstock;
3. cut and thread the 5/8 tenon with it all aligned;
4. install the muzzle brake and check for alignment with the range rod, correct by truing up the hole through the brake if necessary.
Does this sound like an effective way to do this?
