tight space rivet techniques

[mikehoover]

After less than stellar results on my rudder and elevators, I vowed to just use pop rivets in places like this. No regrets.

I'm sure I will encounter bigger challenges than this along the journey, but this is the first challenge I've come to that has slowed me way down.

OK, so I got one pop rivet in on the aftmost hole in the rudder top skin-to-rib location, but now the rivet I just set prohibits me from getting another pop rivet into place from the opposite side. Very tight space there. All of the techniques mentioned thus far have worked great on the rivets forward of this last one, but this last one will require some more head scratching.

Wish I'd known about this four weeks ago doing my rudder bottom rib. I fought it for two hours and got it but it sure is ugly. Now I know about so when I get back around to redoing my rudder skins I'll have it in the back of my mind. I'll have it for the elevator in a few weeks at least and maybe I'll get those right the first time.

Hi Guys

Sorry to bring up an old thread, but whilst researching I came across this thread.

I have riveted my rudder together and am struggling with the last holes in the ribs. I am planning on putting blind rivets in them, but here is my noob question.

The holes are #40 and I will obviously need to open them to #30, but how do you then dimple the skin and rib after you have enlarged the hole, as they are now riveted together?

Also if I put one CS4-4 in the one side, then another CS4-4 won?t fit in the other side as the gap is to small and the rivets hit each other, so do we get shorter pull rivets that aren?t cherrymax?

Thanks in advance

Take a look at the Aircraft Spruce website. Also, Chapter 5 of the build manual. There are several 3/32" countersunk pop rivets available - both with steel and aluminum heads. One or more of those will work fine without having to open up and re-dimple.

Look in your inventory for MK-319-BS pull rivets. They fit the #40 dimple. You do have to drill the hole up a tiny bit.

Wow, thanks for the fast and brilliant responses problem officially solved and MK-319-BS rivets ordered

You can use a # 34 drill purchased at the local hardware store to final drill for MK-319's.
