				RV-8 List Members,
   
  I've finally come to the place in building where I have to attach the top forward skin.  A lot of the rivet locations are about impossibe to get to - especially along the sides in the gear boxes.  I've considered cherry max rivets, but the smallest size is too large.  Is anyone aware of screws being used instead of rivets for this skin?  
   
  If the longerons are tapped and platenuts are installed on tops of the bulkhead, firewall and panel, flat head screws (NAS514 machine screws) could be used.  Also, this would make it possible to remove the skin and windshield, I believe. 
   
  Any comments would be appreciated.

  Hi Breece,
 
  The text below is from my log entry regarding this vary thing.
 
  "CherryMax CR3214 Pop Rivets On Gear Towers
 
  There were about 6 rivets on each side of the top instrument panel skin that were located inside the gear towers. Consequently, getting to the backside to buck them was nearly impossible. I suppose with just the right bucking bar, crafted specifically just for reaching those pesky rivets, you probably could buck them, but of the 8 or 9 bucking bars I have, nothing came even close.
 
  I did a little research on the Net and found that many people have been using CherryMax CR3214 4-4 Pop rivets for these few rivets. These, however, seem to be a little hard to find because they have a 1/8" body, but a 3/32" countersunk rivet head. I found a great source for them, however, at Genuine Aircraft Hardware Company (  http://www.gen-aircraft-hardware.com/store.asp?alternate=CR3214%2D4%2D4  ). These guys have all kind of nifty hardware for aircraft and are very friendly and helpful on the phone. Give them a call and have them ship you a catalog; a resource guide in and of itself.
 
  I ordered 30 or so of the CR3214 4-4 and when they arrived, I drilled the holes out to 1/8" and then stuck them in the holes. The are really cool and leave a completely flush rivet that almost cannot be distinguished from a standard 426 3/32" rivet. In fact, the mandrel of these pop rivets breaks off exactly flush as well, so they don't even leave any ugly hole.
 
  By the way, if you have a decent "standard" pop rivet tool, it should work with the CR3214 rivets as well. No need to buy a special rivet tool."

				Just wondering. Why not use the 3/32 pop rivets that Vans has? Then you dont have to drill a 1/8 hole??

				Matt, I could not help but notice that you riveted the top skin on without having the windscreen rollbar mounted. I suppose there must be some way to mount it afterward? And why would you do it that way? Bill

				Thanks for the information, Matt.  I've ordered the Cherry Max CR3214 Pop Rivets from Genuine Aircraft Hardware Company.  Your airplane, by the way, looks very nice!  <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
