RECROWNING BY HAND

Using a ball from a PC mouse.

Cut the rubber sheath off, I then used some ordinary valve grinding compound on the ball, I stuffed some patches in the bore to keep it theyre and clean below.coat the ball with the v.c. and just spun it by hand slowly rotating the ball to get fresh cutting from the compound.

After I took some 1500 grit emery paper, cut a square 2" and put it on the crown with the ball and spun that with a little oil on the emery to float the grit for an even cut.

Comes out nice and can be done within an hour.

It shrunk the group to one hole. Before it was 1-2" at best on paper.

You dont have to go deep at all just enough of a cut with the valve compound to refresh the lands and grooves.

Go easy with the v.c. paste.it cuts fast.
