I would Google AC43-13, if you want to know how to buck a rivet, its covered in it !

Subject: Re: [Aus-soaring] MORE: Tube rivets Tube Rivets/ hollow rivets? Are they the same thing.? They are used for the spar fittings in the FOKA and probably the COBRA and other gliders. Yes, can replace with an 8mm bolt. But how were they done originally. No one in Aus seems to know! Can you share the info from Katya?

They suggest using 8mm bolts. The story so far: Schiebe regularly used the tube rivets to secure metal fittings to timber work – they look like hollow rivets. Most obvious locations were the metal wing root fittings on the spar stubs and the fittings where the lift and drag pins were fitted to the wing root rib. These tube rivets appear to have been made by Schiebe and not from a fastener manufacturer. During the 10 yearly on GZQ we found the port and starboard elevator hinge fittings to have corrosion on them inside the horizontal stabiliser. Each fitting is attached to a stub of timber which passes through the horizontal stabiliser spar web and is glued to a rib web. The hinge fitting is attached the timber stub by a pair of these tube rivets. The fittings have been removed (and I found damage to the timber stubs underneath). I need to replace the fittings – certainly the stbd one, the port one may be salvagable. I fear that the using an 8mm bolt in lieu if the aft tube rivet on each fitting may foul the leading edge of the elevator – plus it is the heavier option. Katja has kindly sent me photos of the tooling they currently use and supplied the detail on what steel tube to use. Given the number of Motorfalkes around Oz, I was curious to see whether anyone had replaced these types of rivets and would hence have detail on the tooling and technique.

The tube rivets consist of 8mm (or other size) steel tube with each end rolled over. I am particularly interested in the tooling and technique used.
