Does the pad between the tip and shaft change the hit or deflection any?
not really
might soften up the hit of a very hard tip, but that's an edge case at best
Depends on the pad material.
I'm surprised that no one has talked of the original purpose of a pad. Pads were originally used on ivory ferrules. They are meant as a buffer, to stop the ivory ferrule's grain from splitting. As the tip flattens out, it expands in surface area (mushrooming). With a pad the tip expands across the pad. Since the pad doesn't have grain it doesn't split and it doesn't expand in area. Like the tip. Thus the ivory ferrule doesn't split or chip as easily.
As Far as the new low deflection ferrules go and the pads that accompany some of them. I can only theorize that these thicker carbon pads are there to spread out the force of the hit over the entire top of the ferrule. Picture putting a thin mattress over your stomach and having someone punch you. You still feel the punch and the area where the fist was. Although softened. You still feel the area of the fist. Now put a piece of plywood on your stomach. Then that same thin mattress and have someone punch you. The pressure is spread out over the entire piece of plywood. Saving a pain in your stomach. Your stomach representing a ferrule. The plywood representing a carbon pad. The mattress representing your tip. Thus able to use much lighter and less durable material as a ferrule for low deflection purpose.
While not a cue maker. Just a lowly repair guy. That's my 2 cents worth and I'm sticking to it. Jim
Chris and all,It has be established on here that the pad can change the hit. So lets move on to why pads are mostly used. It is to keep the ferrule from cracking. On modern ferrules that are capped this is not as much of a problem. But almost all modern materials that have the hole drilled all the way through should have the pad to help keep the ferrule from cracking.
Chris and all,
IMHO much of the hoopla over tip pads is cosmetic and not functional. We see these pads in clear and all colors of the rainbow. They, are cut from acrylic, polycarbonate, and other unspecified plastics. One proponent even claims his special brand of pad reduces deflection.
Rarely is protection of the shaft mentioned as a function of the pad.
Those of us who have done this for a while, know this to be the primary function of a tip pad.
My 2 cents,
Gary
P.S. Don't even get me started on the trend to use colorful, figured acrylic pen-barrel stock for ferrules!
If it softens the hit. Then the hit has changed. Lol
Those ferrules are uglier than Meth heads.
