The Avery set is flat and I haven't cleated a rivet yet with it (knock on wood).

I had the same problem even using the c-frame to get perfectly square. My solution was to go down a half size in rivet. I ended up with perfectly driven rivets that met all dimensional requirements for shop head height and width and not a single one went over sideways like almost all of them were doing with the called for rivet.

So my answer is that the rivet callout is too long by .5

Best of luck.

Default Back-riveting helper tool

I had a lot of trouble with rivets bending over while driving, too. I resolved the problem by removing the plastic ring and spring from my Cleaveland back rivet set and making a small brass guide block:





It's got flats to apply plenty of force to hold the parts together with my fingers and the block holds the gun perfectly perpendicular to the work.

If you have access to a machine shop, I highly recommend getting one made. It cured my problem.

Matt,

I like your idea, I will have to see what I can come up with. Looking at your pictures, your set is flat as a pancake. Part of my problem I think has been that the set I have is slightly concave.

Does your brass setup still allow you to reach the stiffener rivet that are near the trailing edge?

Cheers

Yes it does. You have to orient it so the short leg of the brass block is towards the trailing edge.

Just some follow up on this since I had similar problems with the rivet set from Planetools. I borrowed a Cleveland set from another builder (thanks, Jamie) and just did my aileron stiffeners with it.

Much improved. I can't say every rivet was perfect, but much easier to center,and the end of the set is FLAT, unlike the others I have.

I'm not saying there isn't some operator error involved in the problem...maybe someone more experienced wouldn't have trouble. But, to me, I think the issue was the tool.

In defense of Planetools, though, when I raised the question to them about 6 months ago they sent a replacement set to me right away. I was supposed to send the original set back but never got around to it. So, I didn't give them a proper chance to solve the problem. I'll send them another email and also send back the set(s). Those guys are top notch and have always responded instantly to any tool problems I have had.

By the way, the tool is stamped ATS 2470S.

Good luck.
