RV10 Kit Ordered

I submitted my order to VANS for my RV10 Empennage Kit last night.  While I was trying to wait until after I did a demo flight, I realized that honestly I had already decided last year that I was building the -10.  I also attended my local EAA chapter meeting and spoke with a number of really interesting people.  The one that really stuck in my head was from another local RV10 builder.  He is pretty far along in the build process (recently got his fuselage delivered) and so far he has not taken a flight in the RV10.  Do you really need to fly in a -10 before you build one?  Honestly you really don’t.

My current thought is this.  I’ve already completed my practice kit, and just about finished my toolbox.  Do I really want to wait another two weeks to order a  kit I already know I want to purchase, then wait even longer for it to be delivered?  NOPE!  I went ahead and ordered it and hopefully it arrives just after I get back from Sun n Fun.  Then I can get started and take my demo flight since it’s really getting beginning to be great weather outside.

Cleaning tools (rust removal)

So while looking for a way to clean some of the rust off the steel bucking bars that came in the tools I purchased of the VAF forums, I came across a post talking about Evaporust.  After a few internet searches and videos, I started to see if it was something carried locally and was willing to give it a shot.

Setup and cleanup was actually pretty easy.  Fill a container with the Evaporust product and insert the rusty items.  Granted most of my tools only had what I would call slight or light surface rust, I still wanted my tools to be in excellent shape.  I let them soak for about 2 hours, then pulled them out to see how they looked.  Rinse them off in fresh water, then dry them off and they are looking great!

Realized I forgot a few bucking bars and figured I would throw some of my used clecos in the bucket to see how much of an improvement it would be.  The result is WOW.  For very little effort, the clecos look so much better, and actually are a bit easier to operate.

I’m letting everything dry off completely and will be spraying them all down with the Evapo-Rust rust block product to hopefully keep them from rusting up again.  This makes my initial purchase an even better value, and can’t wait till I have a few hours to take additional pictures / clean the remainder of my nasty used clecos!

 

UPDATE:  While this worked well for most of my clecos, I don’t think my copper clecos (1/8″) liked this process (or I just didn’t do a good job of rinsing them afterwards).  Something to keep in mind.

UPDATE 2:  While this did clean my silver clecos, they did re-rust. Honestly this was great to clean my bucking bars and other tools but probably not worth the time for the clecos unless you are aggressive with the rust block after. 

Practice Project completed

Yesterday with the assistance of my daughters, I was able to complete the control surface practice project.   I love how it went together, and all the little mistakes I made along the way.  Honestly this was exactly what I was expecting with a practice project to help figure out where I needed some additional tooling, education, or simple practice!

I continue to buy an additional tool here and there, and the most recent that I’m thrilled with are my scotch bright disks for my air die grinder.  I have been more inclined to use them than my scotch bright wheel in my bench grinder.  I feel like I have more control on the pads vs the bench grinder, but that may change as I get more experience and begin to work with more parts.

I ended up mangling a bunch of rivets as I attached the skins to the spars.  This required me to drill out a few rivets and use some “Oops” rivets.  Luckily that worked out perfectly.

Bending the radius in the leading edge wasn’t as clean as I really wanted it to be.  Honestly I just couldn’t bend it enough that there wasn’t pillowing.  I even attempted to use the edge forming tool, but that didn’t seem to help much.  Finally I just went with it and with the help of my youngest daughter, started to blind-rivet the leading edge together.  Daddy and daughter did a great job on 4/5 rivets, however one didn’t seat very well.

Not a huge deal, but I’m planning to drill out all 5 of the blind rivets when my removal tool arrives and install all new blind rivets.  (also debating drilling additional holes and adding more rivets to make a better seam.).  This is the time to experiment and get better right?

 

Practice project. Step 8 completed

Ok, so family visits and lots going on mean I really didn’t have much time to “play” in the garage. I did get the blind rivet dimple tool, but it wouldn’t work on the ribs. Quick trip to Home Depot for some steel and I made the custom dimple bucking bar.

At this point I have the skin, spars, and ribs dimpled. (Didn’t seem like the spar needed to also be countersunk but will have to verify before I begin to rivet.  The squeezer and substructure die combo looks like it was perfect).

Also countersunk the trailing edge. Again need to verify they were deep enough as I test-fit everything prior to riveting.

Maybe tomorrow night I may have time to do some more work.

Progress on Practice Project #2

Ok, so I think I got just about as far as I can at the moment.  Skeleton of the control surface is riveted.  Had a small issue with a slightly folded over rivet so I drilled it out a few times.  (Guess it was good practice for me, so not too upset).

Got the trailing edge drilled and the skins dimpled.  Also dimpled the Skeleton structure with the exception of the tight areas at the tip of the ribs.  Decided to order the pop-rivet dimple tool to see if that will work, or if I need to make the dimple die tool that was part of the project.  (I may make it anyway just to see the difference.  Maybe dimple each rib with a different method?)

Only thing I’m not thrilled with is my edges.  I tried to use my bench grinder to smooth my skin edges, but honestly that didn’t work very well.  Not sure what the “recommended method” is, but I have a feeling this is something I’m going to be asking about when I go to the workshops at Sun n Fun.  I have had mixed success using my bench grinder with the Scotch Brite wheel.  Think I’m just not using it right, or need to work on my technique.

Looks like I’m at a holding spot on my projects for the next week until I get some things in the mail.  Decided to get a new Hinge, as well as two more toolbox kits for my girls to build.

IR training, Weather and Schedules

So I have only had one lesson in the last 3 weeks due to my work schedule as well as weather.  (I really don’t want to see what’s it like landing with the winds are 20G35 in my Cessna 172!)

That one lesson I did have however made it clear just how quickly you can take a step backwards in your training.  First half of the lesson I was having difficulty keeping altitude and heading, but slowly got back to where I needed to be.  Got to try a VOR approach as well as some hold entries.  Overall not my finest hour, but at least I did it.

Question becomes do I try to get in a handful of lessons knowing that I’m going to have a few weeks between now and the middle of April where I can’t fly, or do I just go up on my own and do some pattern work / VFR flights.

Practice Project #1

As I was reviewing the plans the other day, I realized that I had skipped the first practice project completely.  Oops!  So decided I would complete that before I went back to the control surface project.

First step, was to mark up one of the sheets and measure where to center punch for each of the rivet holes.

Using the cleco clamps, make the first hole, install a cleco and continue down the line.  Deburr all the holes, then figure out how to install (dimple / countersink) for the AN426AD (flushmount) rivets.  The sheet is too thin to countersink, and the metal bracket below is too thick to dimple.  I’m totally guessing at this point, but I decided to dimple the skin and countersink the “L” bracket to allow the sheet to sit flush.  (did a few tests on some scrap pieces, and thought this was the best choice!).

Once everything was appropriately dimpled and countersunk, I started to rivet.  Two center rivets were Blind (or POP) rivets.  Fairly easy.

Next, 3 of the AN470 on either side of the pop rivets.  This is where I really enjoy having the squeezer.  A little minor tweaking of air pressure and squeeze distance and my AN470AN4-r rivets were set.

Lastly I set the AN426AD4-4 rivets in the dimpled / countersunk holes.  Honestly I think my dimple or countersink on one of the holes may have been slightly off (or not deep enough).  Looks like the final sheets didn’t sit completely flat.

Sheet to sheet with the AN3 rivets was quick and easy.  If I had additional blind rivets, I might try to drill the first row out and adjust the countersink.  I’ll have to think about it.

Structural Dimple Dies and Back Riveting

Decided to purchase a set of Cleveland Tool Structural Dimple Dies to see how they work since the Practice kit is a great place to try some new things!

Got the Ribs deburred and match drilled.  Used my standard dimple set to dimple the skins, then switched to the new structural dimples to dimple the ribs.  Wouldn’t you know the structural dimples worked as advertised.  (Sorry, in my excitement I didn’t take pictures!)

 

On to back-riveting, went ahead and put the rivets in the skins and taped them down.  Flipped the piece over and added the ribs.  Back-riveted 2-3 rivets before I had to call it a night as I was making a bit too much noise at 9pm.  Oh well, I’m all set up and ready to start again on Friday afternoon.  I have a feeling I’ll have the control surface completed by the end of the weekend.

 

Control Surface Practice Kit – Getting started

Since I can’t make any further progress on my toolbox, I decided to go ahead and open up the other Practice Kit.  This is more like what I was expecting!

First instructions at to fabricate a stiffener using some longer pieces of stock.  EXCELLENT!  Had to sit and stare at the diagram for a bit to understand exactly what was being asked, but think I figured it out.  Some quick work on the band-saw as well as the Scotch Bright wheel and we are all set.  Only issue is that I think Vans has a small error in the diagram.  They put the wrong label on the “R” and “L” pieces showing how to fabricate.  If you label the parts that way, they don’t match the exploded part diagram and layout image.  Easy enough to fix as I don’t see how putting them in “backwards” would cause any issues.  I just relabeled my parts.

I’m ready to do some match drilling but going to hold off for a bit.  Already had lots of fun, and don’t want to finish my new project in one day!

Also, I want to wait for my sub-structure dimple die from Cleveland-Tool to arrive to see how well they work.

All for now.

Mistakes have already been made!

Just when you think you totally understand what needs to be done, take a second look.

The directions for how to attach the hinge to the toolbox didn’t fully make sense to me, but I “thought” I understand what was being asked.  OOPS!, I was mistaken, and the holes I drilled were far too close to the edge of the hinge material.  (The hinge attaches to the OUTSIDE of the toolbox!).  Also when they say that the eyelets should be flush with the top of the box, they mean that the top of the eyelets should be flush, not the bottom.  Oh well.

So this means that I will be putting the build of my tool-box on hold until I can order a new hinge.  Not the worst thing in the world, but slightly annoying.  The debate is, order the part now, or wait until I order the Empennage just in case my next practice kit also needs some replacement parts!

I’ll see if I can do any additional steps, or if I just need to wait until the new hinge arrives.  Bummer.  I was just starting to have fun putting this together!
