    What does it mean for bore type? I ordered Apollo Shawdow FL (55g)wood shafts. I ordered the Dynacraft Evolution 12Degree bore type M1. For a R-flex 0″ tip trimming, but with the M1 bore it says to add 1 1/2″ tip trimming. So for the flex that I want will I have to cut 1 1/2″ from the tip because of the M1 bore?

    Robert:

    Here is an article to show what the bottom of bore to ground line means:

    However, for the Apollo Shadow FL, you don’t have to add to the tip trimming for bore type. That trimming note (A) only applies to a handful of shafts. It will be a part of of the trim code. For example, if it says Trim Code W4 A, then you would add to the tip trimming. But for Trim Code W4 you do not.

    Can you please tell me the tip diameter of the shaft required in the assembly of Hindsight putter? It appears to have a .313 diameter tip.

    Thanks,

    Bob

    Bob,

    The Hindsight putter has a post that fits the inside diameter of a 0.370″ parallel tip steel putter shaft.

    If you use a light shaft in your irons seems to me the swing weight will go up , then you use a shaft weight to bring it back to what you want does this not defeat the purpose of the light shaft in the first place. ????? Or are their other benefits i’am missing , or does the swing weight really go up?????

    Phil,

    Swingweight is the relationship between overall weight and balance point referenced from a fulcrum point 14″ from the butt end of the club. Since the majority of the shaft lies past the fulcrum point, lighter shafts will often yield a lower swingweight. Instead of making the club longer (although a possibility to increase swingweight), the head weight is increased (not shaft weight).

    Making a counter weighted Pustter (Technical article) Can you use lead tape under the grip tape or in my case using masking tape which allows me to use compressed air to install my Grips. Learned this about 20 Yrs ago.
    I have some 3/4 in lead tape. I am going to us the Red winn grip suggested in your tech article. Would this still be trial & error to find the right feel. I also have an aculite malet putter head which has a white circle in the middle of the head. I wondered what its head weight might be if you still have records on these heads 3-5 yrs ago I ordered it. Thanks

    Cliff,

    You would have to use a LOT of lead tape to be effective, plus it will add to the diameter of the shaft. That’s why the Tour Lock Pro counterweights are so easy to use. Re-check the putter head for the name. We have used Acculite name for some of the Apollo shafts but not on any heads.
