Several months ago Vans released a Service Bulletin that affected every model they make except the RV12. I promptly ordered the parts and when they came in I put them in the dust collector. I still have the fuel tanks to work on, but they kill off all motivation the second I touch them. So I elected to start doing other things and coming back here and there. This is also the perfect time as I have yet to put the Aileron Gap Fairings on. Opening up the kit was quite daunting at first. Not as daunting as a new kit delivery, but more of how the heck does this go together. After a few minutes I got my visual and started at it. Once the pieces are cut apart, it is pretty easy to see how it goes together. After match drilling, deburring, cleaning, and priming, I started drilling out the old brackets. This way the parts had plenty of time to dry. The SB requires you reuse an old bearing from the original bracket so I took it apart per the instructions. Assembly was nice and easy. I even had it inspected by a certified sniffer.
Category: 15) Rear Spar
Today I ran over to Home Depot and picked up some new Dewalt 20V Drills. I really did not want to buy any of the 20V stuff, but they stopped producing the one drill I needed in 18V. So I ended up getting the 20V 90d Angle Drill (tool only) and a combo kit that had a 1/4″ impact, drill/driver, 2 batteries, a charger and a bag. Once I got to the shop I immediately tested out the 90 degree drill and it did exactly what I needed it to do. I was able to drill out the conduit holes that I neglected to do earlier. This was followed up by tidying up the shop a little bit.
Next I grabbed the rear spars and mounted the doublers to them and began match drilling. After match drilling one spar, I had to make a hole in one of the doublers match the spar. My solution was to use a unibit to take out a big chunk of the material and then dremel the rest out. With a cutting blade I cut out what i could. then i cut little notches to the edge. Next I used a dremel drum sander to smooth out the roughness.
next i mounted the spars to the ribs and matched drilled those
once that was completed I began disassembling and deburring, cleaning and priming. Once the primer was dry I cleco’d everything back together and began riveting.
Didn’t do much today as well either. I did prime and complete the brackets I started yesterday though. After buying 3 more cans of EZCoat and placing an order for 2 cases. I primed the parts from yesterday. Next I used a 7/16 , 9/16 sockets and my vice to press the bearings into place.
next I cleco’d the assemblies together and began riveting. I started with the flush rivets first and then randomly did the regular rivets. This is to attempt to prevent warping of the entire assembly. They looked straight to me.
Today I was greeted by a box from the UPS man from Avery Tools. I got my SafeAir1 kit as well as some other goodies. There really wasn’t much to accomplish today. I finished up the ribs in the left wing. After that I pulled all the parts for the rear spar and started on the Aileron Hing Bracket Assemblies. First thing was to trim 2 of the 4 spacer brackets. Then I cleco’d the assemblies together and match drilled the #30 holes. Afterwards I marked each assembly and began deburring and scuffing. I need some more primer so I called it a night.
