    Does someone have a good idea for along reach benchtop riveter for solid rivets up to 3/16 in diameter?

    For AD6 rivets? Yow. The forces for rivets that big get huge. Not many open-yoke squeezers can do them.

    Back before even the slow-build RV kits came with prefabricated wing spars, the usual thing was to re-purpose a cheap 10-ton hydraulic press like this one as a rivet squeezer. There used to be web pages about that, but I haven't seen one in a long time.

    The cheap way is to use the C-frame tool you already have and a big hammer. I have done a few AD6 rivits that way. Not sure how well it would hold up to a whole spar's worth.

    For some AN5 and AN6 rivets on our spar, We used an HF arbor press, filed and polished the bottom face of the ram to a nice sheen, and slapped the roof of that bad boy with a deadblow. Sets an AN5 in about 3 solid hits. After about 100 rivets, the locking ring that kept the main axel attached to the handle split, and I had to go in and lathe up a new one from some nice thick steel. (was a fun little project)

    Managed to rivet up one wing this way. Should be able to do 2 more. But I also would like to figure out some kind of setup to weld together for a 10-ton hydraulic ram to sit on a benchtop.

    Paul Dye (kitplanes editor) borrowed another Xenos motorglider builders custom pneumatic benchtop riveter to rivet the spars on his xenos. It looked really nice and apparently worked great. A little googling should turn up some photos. Should be good for some ideas at least. Also if you wanted to spend real money Numax has plans for converting their hydraulic/pneumatic riveter to a benchtop machine. Someone recently posted the drawings to the vansairforce forum. It looked plenty stout.

    Take a look at You tube. Search for:
    SPARivetSqueezer This is a hydraulic set up for -6 rivets on Cougar and Panther spars.

    Also search the net for Panther rivet squeezer. All the info you need to make one. I'd be more inclined to use a hydraulic mechanism like this one, than a pneumatic one. More control.
