Posted: Mon May 21, 2007 5:34 am Post subject: RV8- Dimple Question

Hello RV-8a builders, I am deburring and dimpling the fuselage. Am I reading 28a (2 correct ? Are there five 470 rivets on each side that have the working ends exposed on the bottom ? They are at bulkhead 804. Further, does that mean that the remainder of the rivets along the bottom longren forward of 804 have the working ends inside the cockpit ?  Also, is there something simple (paper, plan {other that Van's} written words, diagram, etc.) that shows or explains precisely which holes are dimpled, their directions and whether to counter sink or dimple ? Such a aid would really be valuable. Hope to hear from someone before I screw up again  , Best regards, Bill of Georgia

Bill of Georgia, the idea is to follow the rivet plan (can't remeber the plans number) and only dimple those holes that call for a counter sunk rivet.  the 470 rivets will be covered by the wing and do not need to be countersunk.  i drove all rivets from the outside of the fuse, bucking on the inside.  you might want to circle the group of holes that do not get dimpled ( i did as a reminder) so you don't have to spend time double, triple and qusdruple checking the plans.  good luck and happy rivetting!

Bill

  

 95% of the rivets in the RV airplanes require  dimpling.  The few that need countersinking will be obvious.

 Note:  there are ok dimple dies and there are GOOD  dimple dies.  I had best luck with the spring back dies from Avery and  Cleveland.

Bill of Georgia,

 You're not exactly getting your question answered, are you?

 I do recall that there are about 5 rivets on each side that have the shop  head on the outside of the fuselage.  I thought it a bit strange at the  time, but since mine is a QB, I assumed the Phillipinos had done it right.

 My hard drive crashed, so the photos I had of the plans was lost, but I  will look at Dwg 28A at the shop today and confirm the info for  you.  In fact, I'll take a photo to send you.

 The Van's RV-8A builder's manual is sadly inadequate.  I jokingly say  it says, "Build wing.  Attach wing."

 I wish Van's would rewrite it to be like the new RV-10 manual, but that is  unlikely.

Stan, thanks for the info. Yes, I think if you have already built an 8a the plans would probably be clear and sufficient, but to a slow county boy they border on Greek in some ways. I found a photo I took at S n F of a 8a bottom and it shows a fiberglass cover for the landing gear that covers the 5 rivet heads so I can see now they are hidden, Best regards, Bill

Dick, thanks for the info. I'll have to look into the spring type dies. Best regards, Bill
