What's a cleco?
I tried the search function, but I'm still not exactly sure what they are and what they're used for. Is it a tool or a fastener, or both? When does one need a cleco? Do I need one to install inner skins or belly pan? Pictures would be helpful.
Thanks.

You weren't the only one unfamiliar with them...
I don't need them but was also wondering how they work.

Simple and ingenious
A cleco is like a minature toggle bolt. They are used to hold aluminum parts together before permanent rivets are put in.
Most clecoes used here are spring loaded and require special pliers to insert and remove. The pliers hold the body of the cleco and push in on the spring loaded stem in the rear. This causes the latching pins in the front to extend.
When extended, the pins are smaller in diameter than the hole. As they retract, a wedge piece spreads out the pins so they are larger than the hole.
Here are pictures showing a cleco in use, then with the pins extended and retracted.
They cost about 35 cents each, the pliers are less than $10. I found them extremely useful for holding sheets together. Especially on the interior skins, you can put the skins on and take them off a dozen times until everything is perfect.
Get at least 2 dozen for a small project, a hundred or more for a skin replacement. They come in 1/8" (copper) and 5/16"(black) depending on the rivet size you are using.

Nice response & pics, Don.
Ingrid, it looks like everybody is competing to get a virtual swig of your French champagne ...
From the rubrail trim (at knee level) and upward on the exterior, bucked rivets were used in manufacture and Olympics without rubber gasket rings (5/32") are the repair choice. Put a little dab of Sikaflex 221 to seal when you insert them. 1/8" pop rivets were used elsewhere; be sure to use all-aluminum only (not steel pull shafts). I don't have a source off the top of my head but the belly pan goes back on with 1/8" pop rivets with wider heads. Anybody? I just made my own little washers by drilling 1/8" holes in aluminum sheet stock, cutting it into little squares and put belly wrap on with that.
Here's a response I wrote up for another member once -- look like Don gets that virtual champagne:
You will want to get a 12" clearance strap duplicator. This will let you accurately drill a rivet hole in new belly skin or banana wrap, so that the hole is located over the underlying hole in frame or skin that you want to rivet together. Go to Aircraft Tool Supply - eCatalog and see .... darn, there's no page number. It's an Adobe Acrobat document. Click the binocular 'search' icon and enter: 62-12 -- You do want the strap duplicator for #30 twist drills since this is what you'll use most often (just ream out afterward with a #21 drill if setting a 5/32" rivet). This is the handiest tool ever and you can thank Forums member markdoane from Minnetonka for the idea.
Snipping metal shears: You won't want scissor type metal shears from the hardware store! In the Aircraft Tool Supply - eCatalog catalog again, search on: Jilson Supersnip -- I haven't needed a 2nd blade by any means -- the original is enough. I also don't know enough to recommend the cheaper one on the same page. These shears are time consuming but reasonable unless you have air tools already or the project isn't a large one. I would use a hand tool like this for such a small job (ie, a single trailer). You won't be asking "why not" on tin snips after you see the undistorted smooth edge these produce! Good tools make good trailers/aircraft!!
In transferring a template or removed piece of belly wrap to aluminum sheet stock, do not attempt to locate or pre-drill rivet holes. That just does not seem to work. That's what your strap duplicator is for. Trust me -- you want one of those! Ask if you need further pointers once you have it.

I got belly pan rivets from VTS- they're awsome- huge heads- large diameter.

Burrrrrr
The major justification for using 'cleco' fasteners is that when you drill through sheet materials, the burrs formed by the drill are trapped in between the sheets. If you just drill and rivet, the cuttings from the drill prevent a good tight and close fit. Clecos allow youy to get the holes drilled and then to take it apart to remove the burrs. It's an extra step, but you gotta do it.

Aluminum drilling tip.
Use a high speed drill motor such as 25,000 rpm. Yes, twenty five thousand.
DO NOT use anything except minimal pressure when drilling.
If you follow the above, burrs are very rare.
Using slow speed drill motors and a lot of pressure, because your in a hurry, will generate many burrs all the time, GUARANTEED.

And be careful using the clecos. It's hard to do, but you CAN pinch your fingers with them if you're not careful. And, no, there were no adult beverages involved in that....manuever.

I want to thank everyone who were too polite to point out that the correct diameter of the black clecoes is 5/32", not 5/16".

Clecos are available in several diameters.
We use both 1/8 and 5/32 inch sizes.
The 5/32 clecos are black colored.
The 1/8 inch clecos are gold colored.
When using "the recommended "olymic" rivet, which is 5/32 inches in diameter, the black clecos are used.

Ha
Thank you so much for all the input! I will need one for my interior skins, it looks like. Yay, I get to buy another tool.

Lynn and I will be in Oakland and Berkeley this weekend. Ingrid, we could save you and Tim a trip and pick the tools and etc. and tell you where we will be. But then again a trip to a vinyard would be difficult to pass up. PM me if you want to do this.

Hi
That would be great...but I don't think we'd be able to use the tools yet, we're still in the shell-off phase. I wouldn't want to take DG's tools and not use them for a long time, especially if he needs them in the meantime? 'Gunner what do you think?

A cleco is any unidentified noise which repeats at regular intervals and varying intensity except when the unit is taken in for service in which case it is absent.

Offer will stand as we visit our daughter and family when we can They live in Oakland. In fact our son-in-law's office is in downtown Oakland. Besides I would like to see their progress.

another question
I bought some electric metal shears. Can I use that to cut the belly pan, or is the material too thick to use that, instead of the Jilson Supersnips?
I could have used those supersnips when I was removing the old belly pan and saved my wrists from looking like I tried to kill myself!
