For those scratch builders out there, what did you use to drive the 5/32" and 3/16" AN470AD rivets in the main spar caps?   I'm considering using 5/32" solid rivets in some places and am not sure my rivet gun skills will be predictable enough to assure that I don't mangle some costly 6061-T6.   The hand rivet squeezers (and even mildly affordable pneumatic ones) only seem to be able to handle up to 1/8" dia rivets.



Thanks,

Doug Sire

Doug,

I used a 3-lb sledge and a flat end punch with a radius die on the 

resting side. This only lasted a short dozen rivets and I bought an air 

gun that had the proper

dies for the same applied setup less the sledge. Went much more 

smoothly, but always recommend you make a sample piece up with 20 rivets 

in it to get the idea

first. Suggest this as best way to keep from dinging good surfaces the 

wrong way. That's easy to do too. Air power is much easier to control 

with practice.

Doug,

I made a very simple rivetting tool out of wood, a few bolts and piece of .5 ID tubing.  It was the best 1 hour I've spent.  I use it to rivet alls sorts of things.  You use a half inch steel rod as the driver, and a hammer to set the rivets with.  I did all my spar rivets with solid rivets (make sure to get the hardened ones).  I'll post a picture.  There are a lot more pictures on my website at:

I modified a 1 ton arbor press after seeing this picture in the photo archives:

Herb Heaton had this idea.  I made some modifications using a rubber cushion to hold the metals together before the rivet tools contact the rivet. and using a 3 or 4 lb. rawhide hammer.  No damage to the arbor press with the rawhide hammer faces, but I did wear out a set of hammer faces doing the center and both wing spars.



Search for spar in my kitlog to get some ideas.

That's Herb's bench not mine.  Must have been before the study.
