Vent clamping?
 
Having gone through the entire fuselage kit, I returned to 29-22 to complete the air vent installation.

I'm using Van's aluminum vents and, given the weight which they impart to the assembly, I'm at a loss as to how they might be clamped while the RTV sets up. I considered magnets, but haven't been able to locate any suitably strong neodymiums locally.

If anyone can provide a link to a magnet that'll serve, I'd appreciate it. Any other clamping solutions would be great, too. :)

Quick clamps
 
Some of the common "Quick Clamps" are reversible so they push apart. I used a 2x2 and clamp to hold both sides against the fuselage.

I am about to go to the hangar and start this right now. I am using rare earth magnets around the vent to hold in place. One inside and one out side, and about 6 or so around the perimeter. I got the idea on here, from another builder. Magnets on a rather large retail site that ships fast. . . starts with an A or something.

If you try this, just be very very careful. If they get away from you they can leave a mark.

I was looking at just that site, but couldn't decide which ones to order. They all begin to look alike and all have at least a few poor reviews, so whom to believe?

If yours work out (including supporting the installed aluminum vents), by all means please PM me the 'A' link. :)

Very clever, indeed. I'm heading out to the garage now to see whether my clamps are reversible.

I drilled a tiny hole in the middle of the naca, and threaded safety wire through it. Kinked on the inside, then used a wood block on the outside. Thread wire through the block, and over the head of a small bolt/ nut as a tensioner.

used rivets and adhesive as well.

I just drilled 4 holes for clecoes to hold it while the proseal dried. Filled holes later with epoxy filler. After paint, you can?t find the holes.

Here is what I did - http://www.vansairforce.com/communit...d.php?t=157434

I used Gorilla tape on the inside and a simple loop of safety wire through the vent eyeball and around the top sill as a double check to make sure it didn't sag while the Proseal cured.
