An old dancing partner since the 80's
CYA gun fool friends:
Taper lapping a rimfire bore.
It's the one part of a contraption, that MUST be done by dedicated artists.........
Who are willing to work their hind ends off, while creating their Art.

CYA friends, when I set out to learn barrel lapping back in the 80's, or maybe the late 70's, I quickly found out that one of the most necessary tools required to properly lap the bore of a barrel, is the lapping rod handle.
So I set out to make one....
The handle must be robust, man sized, so you can put your muscles into it, while at the same time maintaining complete control of the rod, itself.
So this is what I finally came up with.
I tool a piece of iron pipe, set it up in the lathe, then faced one end and counter bored it to fit a roller thrust bearing.
The roller bearing needed a ledge inside the pipe to purchase against.
Then I turned it around and did the same to the other end.
I then welded two lag bolts to the bearing holder, 180 degrees apart.
I obtained two, man sized wooden handles, then drilled them and screwed them to the lag bolts.
These are banded handles......and have never loosened up over the past 40 years.
I then added a Jacobs chuck......
And I've danced with this old friend for the past 40 years.....
