Curt - I will probably paint them just because I don't care for the golf graphics that are on there now. They go from black at the top to maroon at the bottom and also have the maker's logo about halfway down the shaft. Not a huge deal really though.
Samuel - The GG grips are made from kork-o-lon which is similar to EVA foam, so it does have some stretch to it. With the gorilla glue acting as a lubricant it allowed the shafts to slide up into the grip with some assistance from yours truly. The grip just stretched around the shaft. As the gorilla glue cures it expands slightly which also helps keep everything secure. The tips are from Gossamer Gear and they fit the shaft pretty well. A .370" shaft tip may fit better, but I had a hard time finding a 46" with a .370" tip. I pressed the tips on to the point where they couldn't be pulled off by hand(the ID of the tips taper) & used epoxy to set them. They are rock solid.
Clayton - $18.00 for shafts, $30 for grips & tips, $7 for shaft extenders. Including shipping on all this, probably comes to ~$70. The GG grips are the costly part of this project at $22.50, but I really wanted a nice grip. I did find a much cheaper kork-o-lon grip that I think would work OK after I made these. Maybe next time.
Konrad - I'm a tall guy so I needed shaft extenders to make all this work. So, the shaft+extender go all the way up into the grip. There is probably an inch worth of empty space left.
