      Jeff,
       If it was my prop I would take the hub to a machine shop and have the  hub 
      halves "flat plated" (milled) a small amount in order to allow more room  
      between the halves for torquing the prop (per the mfg recommendation). Also 
      make  sure you are using new prop bolts !
       I am not that familiar with the GSC as I am using the Kiev,but as I  
      understand it, it is wood. Wood "moves" more than carbon fiber ,composites etc.
      
      You will have to re torque more often with a wood prop. I have had to do 
      that  with every wood prop I have owned (and that's a bunch !)

      I've had my 3-blade GSC for 20 years.  A couple of years ago, I re-torqued the
      bolts and also didn't have a gap. Sent the blades to GSC and they inspected and
      re-balanced them after which I sanded off about .004 inches from the faces of
      the hub using a belt sander and everything has held together just fine since.
      
      My take on it is that there's no way to tell whether the wood that's inside the
      neoprene sleeves at the roots of the blades has been crushed by over torquing
      although I was the original owner of my prop and knew it's history.  GSC's inspection
      was nice peace of mind though.
      
      Having said that, not knowing the history of yours is the primary problem and by
      strict logic should be grounds for not trusting it.

From: "Jim Feldmann" <feldesign@earthlink.net>      
      
      I purchased a Kitfox IV with a two year old GSC three blade prop.  The hubs came
      together at just under 100 in/lb.  After researching the problem, I had the
      hubs milled .050, then torqued the bolts to 80 in/lb, which left a .010 gap.
      
      Approximately 15 hours later, all three blades departed the airplane in flight.
      The resulting off-runway landing resulted in no injuries, although the airplane
      was destroyed.
      
      I STRONGLY recommend that you DO NOT attempt to save that prop.
      
      Jim

From: "dave" <dave@cfisher.com>      
      
      First off I like GSC props and on the 582 they work pretty close to any IVO or
      Warp all properly set. On the 912 I find the IVo kicks the GSC in the rear. 
      
      I have thousands of hours to back up my statements. 
      
      GSC- DO NOT screw around milling the blocks - They get old and fatigue like all
      of us.  Most GSC damage comes from OVER -TIGHTENING. 
      
      BUT they do rot and get weak, some more than others. 
      
      Here is one that WAS NOT Over tightened. 
      http://www.cfisher.com/gsc/
      
      New blades are cheap - DO not screw around. Most of us have little troubles if
      common sense is used.
