CS4 rivet dimple

On page 07-04 they tell you to dimple for a CS4 rivet. That rivet has a 120 degree head from what I've found. Can I just use my normal 100 degree #30 dimple die for that or do I need to order a different die?

Thanks as always

I ordered the correct dies but I'm not sure to answer your question.

I would say buy the die, you'll need it on the ailerons also. I tried what your suggesting on some scrap and found it not satisfactory at all. Give it a try yourself though and see if you would trust it.

Interestingly I don't see this dimple die set called out in the tools list, but there is a call out for a 120 degree countersink cutter.

They also didn't call out for a #10 dimple set or a #12 CS. Hopefully I get to use those more than once...

I'll go ahead and order the 120 die.

Similar question. The rolled lap section on the front of the rudder calls for AD-41-ABS rivets so I am assuming I do not have to dimple those holes as they are flat head rivets.
