Between post #40 and #41 I took a break from building. Next thing on the to do list was roll the leading edges of the rudder and elevators. I needed a edge breaking tool. I had ordered one of the nylon roller type and it just never made to me. Since every order I make of these "special" tools usually come from the USA and it takes a few weeks I had was kind of out of things to do.

Eventually I asked a follow builder if I could borrow a few things to finish the empenage kit. But with busy schedules that also took a few weeks. So this past Monday I finally started working on the plane again.

Here is what I borrowed. I swear I felt like a kid on Christmas when I could finally get building again. Little did I know what was about to unfold.


Full disclosure, I thought I would roll the LE in a day and pop some pull rivets and be done with it... WRONG!

This turned out to be the worst part of the whole kit thus far for me. I absolutely didn't get how to properly do this. Even after yet another builder send me an email with pictures on how he did it and spend some time on the phone with me explaining his method (THANK YOU SO MUCH) I still had a really hard time with it and spend the better part of 20 hours spread over 3 days rolling these 3 leading edges.

Let's try to start at the beginning.
This is what I started with. 2 pretty decent looking elevators. By the way I primed the outside of the control surfaces during my non building time because I was getting pretty bad filliform surface corrosion at the rivet heads. I talked to Vans about it and due to the climate here I decided the parts were going to need some protection for the time of the build.



I used 3M tape and a wooden broom handle. Size was something like 0.85in. The plans call for 3/4 -1" so I thought this would work well. First I tried to roll them all at once but that didn't work out so good so I did them in 3 sections.

Then I turned it around and started rolling. I had carved the end of the wood to better hold it with some pliers. I also had this self made tool holding the wood from rolling up and preventing the bend close to the spar.


Result wasn't very pleasing. I suppose you can hardly tell whats going on this picture. But Lets just say I had an incredible hard time with this task.


After the phone call from a local builder he suggested to use a 22mm galvanizes pipe. So desperate me went to the hardware store bought exactly that and tried again. The tape stuck better to the pipe than to the wood. Ok. But I was still getting nowhere. Also, I felt I needed different sizes in diameter for the different sections. the small most outer part was easily done at first try with the pipe. The others not so much.

So this was version 2.0


What I found in the archives is that a lot of people had good success with this method: Socket Roller

I actually didn't take any picture because I was just really pissed at the whole time... I did Video tape the process. So if I get bored enough I may throw together a little clip.

Here is one elevator.






Oh yea and 2 roles of tape...


This was a PITA! What bugs me most is that through the whole first kit there have been tricky things but all was due to the fact that I have never done it before and was unfortunately making experiences on the actual parts. But after there was always. "well next time I will get it perfect, because now I know how to do it" Weather it was just use this tool over that or try different technique. But the rolling leading edges had non of that. If I had to do all of them again tomorrow it wouldn't get easier nor would I get a better results. So that was the most frustrating part for me.

I didn't learn how to do it and that is usually the rewarding part of the process

Now that I have complained enought about the leading edges I got to do some things that I did know how to do. Drilling and cutting...

I followed the plans and put the Rod end bearing into the elevators to the correct spacing and attached the elevator to the rear spar of the HS. I had a bit of a hard time at first because I had primed the powder coated brackets and the bolts didn't want to go in. Since the space it tight I decided to drill away the paint from the wholes. I guess this will be a corrosion issue place but since it will be lubed it should be no problem I suppose.

After that they slid right in. (BTW my rear spar of the HS isn't riveted in place because I still need to get it signed off)


Next thing I needed to trim the HS to match the elevators movement. I think the HS is the same as the RV-8 and therefore needs to be adjusted a bit.


Nothing hard. Still took my sweet time. Measure twice. Cut once.


I drilled the corner of the cut with a small drill and then used a dremel tool to cut the rest.



Deburr


Repeat 4 times... DONE!

One little modification I have done to my tail feathers I had previously written about. I had used this flexible cable tubing in the front end of the VS going to the top because I am planning on having an antenna and / or a camera up there. The idea was stolen from others on the forum, but my design was flawed. I didn't notice this until I accidentally moved the VS abruptly and it had made a disturbing noise. The hose being flexible and the VS being tight caused contact with the skin.



Just to give you an idea what type of tube I had used.


Glad I caught this now rather than later. My new solution needed to be something that didn't move. So I bought a light weight pipe made of fiberglass. Cut to length and installed.

I feel your pain on them leading edges, they were not easy to do! I found that the front of them had to have a tighter radius than the section closest to the spar. Your rolled edges look great though!

Thanks. Don't let the pictures fool you. But I just saw yours. They look perfect!

While I have never flown or sat any RV7, a friend sometimes takes me flying in his RV-9A. This always motivates me but a few weeks ago he let me get some stick time from the right for about 30 min. The -9 feels so nicely compared to the spam cans that I am used to.

I hope the -7 will be even better!

Remember when I said “I will be back” ?

Well I am and come bearing news: I have received my RV-7 Wing kit and it all worked out in the end but it was a very long journey with quite a few bumps along the way.

The following is my PIREP about buying a used RV kit. This may or may not be of interest to you. So feel free to skip it.

- - -

I had talked to multiple people that were selling wing kits over the past 8 months. Two deals fell through very early. Either because the seller didn’t want to deal with me shipping the kit outside the continental US or simply because of the stage of build that the wings are in. Once the ribs are attached to the wings the size of shipping crates would have to be huge. The kit price would have had to be very low to offset the crating and shipping charges of a halfway assemble wing kit.

I decided I was looking for a “barely” started standard build (SB) kit that could still go back into a crate of reasonable size.

What I found back in beginning of February was a used kit that was advertised as “unstated in original crates”. I was not able to inspect the parts because they were located in the USA and I am not. Flying over and looking at them would have made any savings insignificant.

I thought to myself “well that’s perfect, they can just pick it up and it will be easy…”

NOPE! Far from it. I must have send about an email a day for about 3-4 weeks until everything was finalized. I received a scanned copy of the original shipping list. With that I called Vans and talked to them about it and about risks and concerns. They have a pretty good guide on buying used parts. I must admit they were more against buying used than for it. They probably have their reasons based on past experience.

Well stubborn me at that point really wanted those wings. I went out and got a bunch of quotes for shipping since I had the dimensions and weight of the crates off the Vans website that was easy. However, the long 186“ crate ruled out a lot of shippers. Fedex wouldn’t not touch it. I received a very good quote from UPS, or so I thought.

I had made my final offer and agreements / contract based on that quote.

Even though I had the quote in writing the way their conditions (*) are written they can pretty much charge whatever they feel like after pickup. What happened was that I called them to get the quote. Without my awareness due to the oversize of the crate I was forwarded to UPS business end. I did buy these wings as a private person from a private person. So no business involved. I was then told that if that was the case the quote was no good and they would not give me another one or ship these at all.

So after I send a bunch of money to the seller in good faith I had no shipping arrangements and I had to start all over.

For some reason until then I had never been asked about the wood and crates, however little did I know how important that information was. I was then told that if the crates are not “ISPM 15” stamped they would not be able to leave the USA on any kind of vessel. This is a bug regulation to prevent bugs ruining forests in other countries.

Oh boy! I bought a set of wings in crates with no such stamp.

I called vans and asked them if they could verify that their crates were made to ISPM 15 standards. They send me a copy of their membership with the organization that gives out that stamp and they told me they have been making crates to this standard since 2006. My wings are not that old but they never bothered to stamp the crates because they weren’t meant for international shipping.

SERIOUSLY?

Yes, I have crates that are perfectly good and I have to trash them because they weren’t stamped...Go figure.

This is what the stamp should look like by the way.


The next days I spend getting yet another set of quotes that included repacking the crates and shipping. Cost a bunch of money more but at least someone was willing to do it.

Next issue I had not foreseen: All of the quotes based from the US to the nearest sea port. I thought I could just pick it up there, deal with customs myself and take the kit home with me. Well after further investigating I was told I can’t just do that. I need a local shipping company at the port to deal with unloading the crates from the ship and putting the in storage, then they will deal with customs on my behalf and then I can come pick it up.

I asked the US shipping company to give me a contact information of their partners at the port of destination. They gave me a name and I called them up and asked them for a quote of fees for their services. Yea, that was another hard blow. They wanted about 580$ for the handling things at the port!

In the meantime, I was figuring out that while I can drive a trailer I cannot legally pull one long enough for the long crate.

Another call to the guys at the port: they will happily deliver the crates to my house for another 615$.

At this point I was pretty much crying inside since the ocean freight is less than the handling fees and a home delivery of 200 miles of trucking.

OMG! What a nightmare...
