What do you mean by using the bore on both ends?Easy way is to use the bore on both ends no indicating, no barrel marks, no special jaws,
I threaded two barrels while the customer was standing watching me
His comment the last guy charged an arm and a leg
He did not realize how easy it was the previous fellow had to make specials jaws and special tooling.
Another happy customer
What do you mean by using the bore on both ends?
If you have a cylinder and you want the machining concentric with the bore what would be the easiest way to get them in line on a lathe.
A rifles bore is nothing more than a cylinder you want something concentric with.
Working between centers means no fancy spiders, no fancy fixtures, no indicating
The old toolmaker I learned from beat into us "SIMPLEST IS ALWAYS THE BEST"
He said you can screw around a half a day for a half a thousandth and miss it a half an inch!!
