Bob - thanks for your reasoned response. I'd like to hear more about
how you lined the drift along the rivet axis so that you got a
symetrical mushroom head - Mike

Mike, I just held the drift as straight as I could eyeball it and
whacked it with a claw hammer. There are a couple relevant photos in
the latest HP-24 project update:

Thanks, Bob K.


That's just as I've envisioned and tried, except I was using standard
head rivets (placed in a slight indendation in my anvil to hold the
head). I thought maybe my problem was using hard rivets, but that's
what you are using - Mike


That is the way almost every Sonex builder sets the 300ish solid rivets in
the wing spar.
