I decided to at least try using the squeezer on setting
rivets in the 703/704 ribs. If I couldn't make it work then I would try the
hammer and punch method. It turned out that using the squeezer was not so bad.
It was a bit of work to slip the yoke over, insert the dies, adjust the dies
and then squeeze. But once your set up and set the first rivet to the proper
amount, all the other rivets come fairly easy. It's just a matter of moving
cleco's around in order to move the squeezer. I ended up only having to drill
out one rivet and reset it.
Update - See May 24ths post. Don't set these rivets just yet!
