Default Tip: Leading Edge rolling tool

After a less than ideal experience rolling the leading edge of my rudder, I decided to try a different method for my elevators. I think I’ve come up with a new tool that makes this task quick and easy with minimal risk of damaging skins, etc.

Start with a 1.25” closet rod from the Ace Hardware aviation aisle. A 7/8” socket fits nicely within that rod so pick up two of those. A couple 3/8” to 1/2” adapters, a couple 3/8” ratchets and some JB weld and you’re ready to go! Assuming you have the 3/8" ratchets in your tools box, materials are under $20.



Cut the rod to the length of the skin that you’re working with. I scored the inside ~1 1/2” on either end with a dremel tool, cleaned the inside with acetone, and drilled holes around the outside to give the JB Weld a little more to grab on to. Score the outside of the sockets with a angle grinder/ cutting disk.



Mix the JB Weld and coat the outside of the sockets. Insert the sockets into the closet rod (might require a little bit of encouragement from a hammer). Clean up the excess JB Weld and let cure for a few hours. I also wrapped a bit of duct tape around the ends to avoid scratching airplane parts.

Once the JB Weld has cured, insert the ratchets and/or 3/8” to 1/2” adapters and the tool is complete.



Tape the rod to the surface to be rolled, insert the ratchets and ratchet away. Press down gently while ratcheting forward. This method gave me a very nice roll and I was able to get the rod right up against the spar. (With the J-bolt method, I was still 1/2” to 3/4” away.)

Nice idea! Certainly more sophisticated than what I did!

Default Stopping by Ace Hardware and Aviation Supply on my way home

Eric,

Great post making a PIA job much easier. First time through this on an RV-9A I clumsily used a piece of galvanized pipe, duct tape and vise grip pliers on each end and ended up with barely acceptable results.
Been putting off rolling the LE's on an RV-8 stab and rudder and this looks the ticket to a far better job.
Will give it a try over the weekend.

One thing I forgot to mention. I used 3/8" ratchets instead of 1/2" because the diameter of the 3/8" ratchet is smaller than the 1 1/4" closet rod. Avoids damaging the edge of the skin where the ratchet would have rolled up on it.

Good luck!

Default I like it

After so-so results with the plans method on my emp, I think I'll try this for the wing control surfaces.

Thanks!

Chris, your signature says you're building a 7A. The wing control surface leading edges are not rolled like the elevators and rudder. The flap and aileron leading edges come from the factory close enough to install without further forming. (At least they did in my 2012 wing kit.)

I will be re-skinning my left elevator (botched trim tab opening, of course), and am making a mental note of this thread...

Trip to harbor freight for disposable sockets added to weekend todo list. Thanks!

Update: HF doesn't carry individual sockets but they're only $2.50 at Home Depot. Got the rod there too for $10

Put some thought into the length measurement for the closet rod. I ended up making two because I didn't put enough thought into how long/ short it had to be. Keep in mind the space needed to insert and remove the ratchets and/or extensions.

So happy to have this step behind me. I might actually end up re-making my rudder because I'm so unhappy with how it turned out before figuring this method out. (That and I want to add electric rudder trim )

Default Great idea!

I actually just sat down at the computer with the sole purpose of searching the site for suggestions on how to roll the rudder leading edges on my 14A and found this post on the front page! I finished the rest this morning and have been dreading the rolling - afraid I would wreck an otherwise nice looking rudder! Thanks for the great ideas. I'm off to the hardware store!

Default Providential timing

And Kudos for the main page management putting this one out front.

I completed RV14 right elevator root rib close out last night and moving to tip closeouts this afternoon..... so leading edge rolling will be this next week sometime.

This method will be awesome and I will get my pieces and parts this afternoon when out. It will also come in handy for the rudder redo I have planned.

Thanks for the excellent tool idea and to VAF for putting on the front page!!!
