I posted this first on the Grumman Gang and John Cotter suggested that I post photos here. So here they are…with the original GG post and some additional background information.

I do a similar thing to what Linn described, but used 2 pieces of 9 inch long x 5/8 inch dia. thin wall stainless steel tubing covered with clear vinyl tubing, and inserted through 2 inch wide red nylon webbing. The tubes are separated by 1 inch for the ailerons and by 2.75 inches for the elevators. Leave an extra 8 inches of webbing to act as flags. Aileron locks go in the slot between each aileron and its wing tip. Elevator locks go in the slot between each horizontal stabilizer and its elevator tip. Neither moves with them in place. I have never had one come off. I will be testing polyester instead of nylon for better fade resistance.

Here are some links to where I got the parts. The SS tubing came from Amazon. I purchased a 72 inch long piece for about $9 and cut the 8 pieces 9″ long each. Cost is now about $11 with free Prime shipping if you’re a Amazon Prime member:

I ordered the webbing (straps) from these guys. http://www.strapworks.com/Default.asp

I originally ordered red nylon 1.5 inches wide. As you can see from the photos the red color faded badly in the 2 years I’ve been using them (all outdoors). The width is just adequate. I think 2 inches is better. So I’ve purchased some 2 inch wide polyester and will try that starting sometime in 2016.

Using a 7/16 hole punch and hammer I cut holes in the webbing so the inside edges of the holes were about 1.25 inches apart for the 2 aileron locks and about 3 inches apart for the elevator locks (the 1/8 inch wall of the vinyl tubing reduced the gap to 1 inch and 2.75 inches, respectively when fully assembled). I used a propane torch to melt the edges of the holes to prevent fraying. This enlarged the holes to about 9/16-5/8 inches in diameter.

The vinyl tubing is just 7/8 inch OD x 5/8 inch ID clear vinyl that I purchased from a local hardware store. You can also get it at Home Depot or Lowes. I cut 2 pieces 4.5+ inches long for each 9 inch piece of stainless steel tube. I immersed each piece of tubing in hot water for about 30 seconds to soften it, and wet the surface of a piece of tube to lubricate it. Then I slid a piece of vinyl onto one half of the tube leaving about 1/8 inch overhanging the end. The I inserted the stainless tube through a hole in the strap, wet the surface of the exposed tube, and slid on the 2nd piece of vinyl tubing so that the webbing was clamped in-place between the 2 pieces of vinyl tubing. This left about 1/8 inch of vinyl tubing overhanging the outside of the stainless tube.

If you ever need to disassemble them, just immerse the tube in hot water for several minutes and with some effort you can slide one of the pieces of vinyl tubing off the stainless tube and remove the stainless tube from its hole in the strap.
