reshaft question

[blackyatx]

I am trying to reshaft my flyz+ 3 iron from cobra that I noticed was an KBS S+ when I last regripped it (vs R+ in the rest of the set).  The specs say a 0.355 shaft is used, so I bought one at golfworks and well when I pulled it, it seems to be a little loose.  So I inserted a 0.370 graphite in which fit much better, or at least like all the other reshafts I have done.  I checked the pulled shaft and it is a 0.355 and gives the same amount of play as well.  I did not see any glass beads or shims upon removing so I assume the OEM did this on purpose or the hosel bore is out of spec.  I reshafted the set GW, 3 years ago, but do not recall this issue.  Has anyone else observed this behavior before?    Since I live out in the middle of nowhere and mail takes a month or more to get things lately and no club builders within 2 hours, I am wondering if I could just use an epoxy with gap filling properties instead of a shim?  I see people also have used meshed dry wall tape with success (can anyone provide a link?), which really just seems to be a way to keep things straight versus making a stronger bond (given what the OEM did).  Glass beads and shims are out due to time it takes to get here.  Sugar seems to be a bad idea, and I have seen sand which seems too messy to me.

Note, I wanted to reshaft because I think the S+ is causing distances shorter than expected distances.

Any thoughts?

Like how loose is the 0.355? It's not supposed to be a super tight fit in the hosel, otherwise there would be no room for the epoxy between the shaft and the hosel. However, it should not be super loose either.

I don't know how to answer "how loose" without some sort of measurement tool.   The 0.370 graphite hybrid shaft fits like all my other reshafts meaning I can stick it in and rotate it easily and the shaft stays aligned with no/minor lateral play.  There is more lateral play with the 0.355 and there is a lot with a 0.335.  I have reshafted 6 others that did not appear to have any lateral play (shaft goes noticeably crooked in the hosel).

Would you be able to take a quick video with your phone of how loose it is. 

The part about it going in crooked doesn't sound good.

If you inserted a .370 and a .355 I would make sure the depth of insertion. 

If the .370 is the same use it. If not the .355, Use a shim. some folks have used a sliver of pop can or fishing line
