Rolled Rudder Leading Edge

15th August 2009

This was the first of several rolled leading edges in this airplane. The trick is to make sure you hold the pipe your using to roll the edge with down hard against the bench. If it lifts off the bench you’ll get a crease in the skin where the spar ends. (don’t ask me how I know)

With the new baby in the house it’s hard to find a second pair of hands so I really needed a solution that meant I could get this done by myself. After a quick search on VAF I have to thanks Dan Horton for this excellent idea.

I made up a couple of 'J-bolts' from some screw in hooks. I cut them down and straightened out the bend a little. Here is the before (bottom) and after (top).

The J-bolts hook over the pipe and hold it down while you turn the end of the pipe with a wrench.

I did the rolling in sections which I found easier to manage and meant I didn’t need as much force to turn the wrench. As you wind the leading edge rolls up and the control surface (rudder) slides forward across the bench. this worked really well.
