Time to finally start priming interior parts! Unfortunately, today was met with several hold-ups. I’ll come back to those further down.

In addition to building a proper, albeit ugly, paint booth, I’ve been studying up on proper paint techniques and procedures. Here is a set of videos on YouTube that speak about tools, techniques, and safety equipment.

I started by priming the outside of the old aileron skin I had laying around. 

Slight orange peel, but not terrible. I was trying to practice proper application techniques in preparation for spraying actual paint, but two things made this difficult. First, the stupid cheep orange air hose from Harbor Freight absolutely gushes oil. Now, keep in mind, this hose has never been used with an oil compressor or oil unit. The oil is literally seeping out of the cheap plastic! In the middle of the priming session, I stopped, switched filters, as the first one was saturated, and attempted to blow the oil out of the line. It made it better, but still didn’t solve the problem entirely. Secondly, my cheap Harbor Freight gun is no longer spraying an even pattern. Now, I can’t really fault a $19 gun, that thus far has served me well over two years. But, its going to be time for an upgrade to a professional (or semi professional) setup if I plan to paint the entire plane myself. 

I primed almost every part that will never see a topcoat of paint. Floor stiffeners, the undersides of the floors, and the like were all completed today. With the paint gun issues, and the oil in the line, I didn’t want to take a chance with any of the parts that would see paint.   

The new primer is fairly easy to work with. It takes a little longer to dry than AKZO, so I’ll report back on how tough it is.   
 

So after, my first day in my paint booth, I’ve learned several things. I’ve already covered the gun and hose, but the paint booth will also need a few adjustments. I need a set of shelves, as going in and out of the paint booth is difficult and problematic. I also probably need more airflow. I’ll need to give this careful consideration. Perhaps a third fan and more inlets. I will also open up the rest of the barn more to create maximum airflow. Even with a brand new mask and filters, I still feel a little light headed. I couldn’t smell anything through the mask, and it was of the appropriate type. I think the times that I took it off outside of the booth over the course of the day was enough.  All in all, I’m happy with the booth and my setup. More tweaks and practice to come.

First up, installing the filter on the compressor. Now, you’re supposed to install filters downline, at least 50′ from the compressor for maximum effectiveness. Right next to the compressor, most moisture will pass straight through. Regardless, I don’t have the room, time, or desire to plumb my portable compressor, so this will have to do. 

A little riveting action holds it all in place!  

With this complete, its time to start the installation of the rudder pedals. To make things easier I removed the bulkheads from the baggage compartment. While I’m at it, I’ll put new primer on those puppies.

I am installing the ground adjustable rudder pedals. The first step is to mark a centerline on the two angles that will hold the rudder pedal axels to the floor.   

Then you need to work on the friction bushings for the rudder pedal axels. I hate working with this plastic. Be careful how you orient the cuts and holes. Van’s, in true form, has provided the absolute bare minimum amount of material.   

After cutting the pieces out, I drilled the largest center hole first. This allowed me to mount the friction bushing and then match drill the final two smaller holes.

I used the first completed bushing as a template for the second.   

Here are the finished products.

Next, I put the rudder pedals together to check certain measurements.   

First you need to check that the outside edge of the angles is 15 1/4″ apart. As you can see, I’m spot on. 

This needs to be 1″ from the floor. Bang on again.  

Now this is where things get interesting. Earlier, I had to drill out, and replace a few AN470 rivets with flush pop rivets. However, the holes for my angles are immediately overtop of these rivets. I double and triple checked the measurements. 

Here’s a close up. You can see the center of the pop rivet almost directly underneath. There is no way this is going to be drilled for another rivet. I suspect it will have to be left empty.
  

The same is true at the other end.

I’ve labeled all the appropriate measurements, per the drawings, so I’m not sure why its so far off.   

As you can see here, the rivet I replace should not be directly underneath the angle. I don’t see any solution except to forego putting a rivet in this location. 

At the forward side, you are supposed to file a slight relief. This will not work in my circumstances. I’d need to file half the angle away! I’m going to sleep on this and then possibly contact Van’s support to see if I’m overlooking something.

The last project for the day was to start on the rear rudder pedals. I primed the insides and then drilled for the threaded ends. I cleaned the primer off later with acetone.
