How close can you get a grip to being in the right spot? I frequently use ribbed grips so it's important to get the top alignment mark right at 12:00. And same with the flat spot of a putter. It's a pain in the butt, pun intended, but I usually can get it right. And a head is a lot easier to fiddle with during gluing than a grip that's a little off. On irons I use the score lines as a starting point. On woods, I find the graphics on the sole usually run due east-west. So with those I hold the club out in front of me, sole closest to me, face skyward, and shaft pointing away. I do my best to hold the head with the graphics dead plumb, then sight down the line and gingerly rotate the shaft till my 9:00 mark is straight up. Then extra-gingerly try to set the club down for drying. Then do it 3 or 4 more times cause it felt like it moved when I was handling it. LOL. I use shafting beads because they make it easier to handle the club at that point without it so easily rotating off the mark. 5 degrees is a lot of rotation. I would bet I get my mark glued up within +/- 2 degrees, and maybe 1. If I really am that good, :), then the next question is how accurately can I get the shaft marked. I think I get the mark made accurately too. BUT... The most vague part of the whole operation for me is deciding where to put the mark. Steel shafts with bends are easy in my program. But graphites usually have a pretty wide NBP in my bearing finder. I can see why the NF would improve that. SO, I think I can draw the line and glue to the line pretty well. Not so confident about finding the damn spot to mark in the first place though. Doug Clark
