This is a strange one. A customer wants a set of Maltby irons, on their set of FSTs. Upon removing the older heads, and drilling out the old epoxy in the shaft, I noticed that I could not fit a ram rod through the shaft. I removed a couple of grips to investigate. There appears to be some blockage in these shafts. I immediately thought it would be pro soft insert. It’s not.
it appears to be some foam material possibly used as a make shift insert.
I heated the portion of the shaft that appears to have this strange goop, and it did melt. I’d like a pristine inside of the shaft.
Here’s my idea.  Because it is a foam substance, I might be able to drizzle a little acetone down the shaft to loosen up this up. Good idea? Bad idea?

ps .. the strangest shaft interior I’ve ever seen is a totally plugged shaft of unknown putty material. I an only surmise someone wanted a heavier shaft as a training aid. All quite strange.

so back to the McGyvor acetone idea. Might it work.  Thanks

talk to the customer and see if he knows what it is. I agree with Britt, replace the shafts. Depending on where the stuff is at in the shafts, might be a bear to swing weight these!
need for it to vent when installing the heads. I would recommend:
49 1/2″ Long Drill Bit – 7/32″ Bit Size
The GolfWorks SKU: GW1045

Thanks. The guys oblivious to what it could be. I’m thinking this is a home made vibration dampener. Sure is strange though. I think I can get a decent amount removed. Here really likes the FST. I feel what he really means is the softness of the FST regular.
I’m going to get him to try him with a Score shaft, and trim between a Regular and Seniors.
Riafoone, that’s one long drill bit!
