Nut launchers!
Please, lets call them what they are.
Nut launchers.
But really, I use the technique that Dan H. described. Lots of times, you just can not get to them with all the fancy tools. But you can always make a lasoo of safety wire to sinch them. It takes about 10 minutes to be methodical, disciplined, and do it for every nut launcher.
But if you try to take a short cut, and spend an hour with it, plus the bent/broken fingernails, lost nuts, frustration. So, patience grasshopper, use the wire loop method if you can't get a tool on it.
As to twist ties, the best use for them might just be to lassoo the nut launcher closed while you get the bolt through. I haven't tried it, but if it works it would be faster than a safety wire loop.

Safety wire is the only way to go ....
Until I learned that trick, I cussed those $%^&* adels till the air in my garage was blue. But a word to the wise ...after the adel(s) are in, make SURE you cut the safety wire and remove all of it. I put a horrendous scratch/cut on the back of my hand two weeks ago when I found a little stub of safety wire sticking out the backside of an adel connection that I installed a year ago ... it was invisible from the front, but my hand sure found it.

There's a great thread just waiting to happen: Alternative names for things we use to build these crates.

Hemostats...
work great. You can buy them at SNF or AirVenture. They are less cumbersome than the modified ViseGrip tool and have a latching feature that frees up your hands to insert the bolt and apply the washer and nut. They come in a variety of sizes, curved or straight and work well in tight quarters. They aren't high quality but I wouldn't use them in surgery anyway. I plan to stock up further at SNF.

"Nut launchers"...Funny!
Thanks, Kay, for starting this thread. I spent last evening installing two Adel clamps, and the Frustration Meter was in the red. Lock wire next time for sure!
Question: are Adel clamps always secured with AN3/AN4 bolts, or are screws sometimes used? It just seems that bolts are overkill. What nuts are used ahead of the firewall?

Zip Ties
I had a 'few' zip ties scattered around FWF and the FSDO inspector made me remove them all and replace with Adel Cllamps. In retrospect, I'm glad he leaned on me- The clamps are much more tidy and secure for the long run. I do confess that some of the Adel clamps were tough to secure. Just take a deep breath, relax, and you'll get it done.

The other thing that I have found works are surgical clamps. They can be put on the two end of the Adel clamp and they lock it down until you get a nut on. There are serval types: straight,curved, tonsil (90 degree bend), Kelley, and needle driver. Also, if you have an odd angle you can heat them and bend them to get the correct angle.
Just another toy, errr tool in the box.

I've been doing a lot of engine work over the last week or so which involves a lot of Adel clamps. My fingertips are bruised! I have used the techniques described here and have the tools which certainly help but......
I have one clamp holding the oil breather tube to the firewall which I guarantee is NEVER going to come off - took me 3 hours to get it on!

I hear ya, man ... after I got that one on, I swore I'd sell the plane before I'd ever remove it.
