A very simple question

[VALENGO]

Well, a very easy one: how works the little pins used in aircraft restoration?

Thanks in advance.

Clecos - they hold components together when riveting them together

Yes, sir, I mean the procedure for tightening and taking them away.

Edit: I supose that you put one half of rivets and then the other half.

There is a special pair of pliers that gets used to install and remove them. The Clecos have three wire parts. and the middle one withdraws for installation and extends to enlarge the other two to the exact doameter of a rivet when set.

Looks complicated but is quite simple in practice. Each has something like 70 pounds of clamping force and keeps metal sheets joined together during both fabrication and subsequent riveting.
