I may be wrong on this, and you might want to get other clubfitters to chime in (I'm pretty green), but don't give up on these quite yet. (I should probably just take these off you for $30, but I have enough crap already).
Whoever built this set was all over the map. I don’t get it. He obviously disregarded or did not notice the numbers on the shafts. But the beauty is that whoever did this was obviously building a set WAY over “standard” length. This gives you quite a bit of latitude with what you have left.
You really only have two problem clubs: the 5 iron and the PW. This problem is fairly significant for a "standard" length set, with a 38" 5-iron (the first example below), but I don’t think it is beyond fixing. But if anyone wanted to build a set of irons 1/2" under standard, the problems with these shafts almost goes away and 3/4" under, it completely goes away.
The build lengths/remediation strategy below assumes four things:
1) The shafts were not tip trimmed -- PXs should not be tip trimmed, so if whoever built these things did that, well…they’re hooped (and considering the build numbers, anything’s possible)
2) A grip cap of 1/8 inch.
3) The BBTG measurement for the set of irons is 1.5", which is the case for most of Wishon's irons, I believe. You would have to find out what these are for the heads that were being used. I think the 1.5” is pretty common, though, but I have I seen 1.25”.
4) The set is built with 3/8" length differentials between irons (which I like and produces closer to a MOI matched set).
Assuming the points above, for a "standard" length set, you would do the following to the shaft with the corresponding numbers on them (all trimming is butt trimming):
3-iron shaft: trim 1/8" and use in the 3-iron head
4: trim 3"
5: LENGTHEN 5/8" (that a fair bit, but I think most fitters will be okay with this)
6: trim 3"
7: trim 2 7/8"
8: trim 2 3/4"
9: trim 2 5/8"
PW: LENGTHEN 3/4" (again, that’s quite a bit, but I think most fitters will be okay with it)
For a set 1/2 under "standard" length, you would do the following:
3: trim 5/8"
4: butt trim 3 1/2"
5: LENGTHEN 3/8" (no problem)
6: butt trim 3 1/2"
7: butt trim 3 3/8"
8: butt trim 3 1/4"
9: butt trim 3 1/8"
PW: LENGTHEN 1/4" (again, no problem)
Of course your other option is to build these to a single-length, but your PW shaft becomes unusable unless you are building them at an 8-iron length, 1/2” under standard. Even then you have to lengthen the shaft an inch, which is more than I would lengthen a shaft.
