Hi,
Thanks for your prompt reply.
But if you tip trim accordingly so that the steps match the shafts in the set, won't the #3 iron match the set except for shaft weight.
I'm an club maker in Australia and have done the above to my own #6 iron using a TT #3 shaft when I snapped the original shaft and notice no difference in feel or flex and hit distance taking into consideration the #5 and #7 shaft is about right.
I've extracted the original #6 snapped shaft, aligned 1st lower step, marked original tip location, then tip trimmed the #3 shaft and made a couple 1/4" Dremel cuts on the tip so that the bottom of the shaft conforms to the taper. If I line up all shafts in order, the steps match, distance from ferrule to lower step reduces as clubs get shorter.
For the butt end, grip installs without issue as butt is trimmed to length maybe a 1/2" or so.
As I said above, not ideal but as shafts are replaced, it's harder to track down a replacement.
