I mentioned this methode of using a brass and cutting it and inserting a spring. The brass with the spring created force on the bolt so you could then lap the lugs. Do your own research on lug contact recommendations. I recall that most lugs make contact with less than 10%....usually. You want 80% and anything beyond that was anal. I found the article about making the tool:
