Month: May 2017

This is a pretty short update.  Since I didn’t do the best job cleaning up the tank sealant on the trailing edge of the rudder I had a bit of work to remove the sealant that seeped out.  I went ahead and finished up the steps on Page 7-10 (even if I was a bit out of order on a few of them).  For the trailing edge double flush rivets, I decided alternate the shop heads of my rivets.  Not sure if that will be a cause of concern in the future, but honestly I think it’s fine.

Before I roll the forward edges of my rudder, I had a minor accident that left some creases on the top of my rudder.  Basically I had the rudder standing up on its end and a nice gust of wind knocked it over.  At the time it happened, I felt like this was the end of the world.  I’m finally calming down and think that it’s mostly cosmetic and something I can fix.  I honestly was thinking I would have to scrap the whole thing, but think I can correct the damage.  Hopefully at worst I will have to remove the top rib and use some wood blocks to try to flatten out the skin a little bit?  I’m absolutely following up with a note to VANS, but in the grand scheme of things this isn’t a big deal.

I’m expecting some help in the shop this weekend, and plan to finish up the Rudder (Chapter 7) and possibly make a good dent on the Horizontal Stabilizer.

In a previous post I was discussing the fact that I can get some of the 3M tape to use on the trailing edge of the Rudder vs using the tank sealer.  After doing a bit more research I was seeing multiple comments from people that were getting better results using the Tank Sealer approach vs the 3M tape.  Since I will have to use the tank sealer for the tank anyway (and already had some sealer on hand) I decided to go with the tank sealer method.

Set aside a 2 hour block to make sure I could get it all done.  I previously purchased a mixer adapter for my drill as well as a surplus sealant gun.  I ordered a 3.5 oz tank sealer in a tub so I could easily mix it up and use the dispenser.  Honestly it wasn’t that big of a deal.  Maybe if I was mixing it manually and didn’t have the dispenser things would have been a bit more difficult.

Using the gun I dispensed a line of sealant on the Trailing Edge, then spread it thin using a wooden stick.  Apply to both edges, then cleco into place just to hold it down. The directions recommend to get a second person to help hold the top skin while you blind rivet the ribs, but I didn’t have one.  Some scrap wood to keep the skin off the Trailing edge and the sealant, and I was good to go.  (My big hands don’t work well in those small spaces, but that’s just me.)

Currently this puts me at a work stoppage for a bit while I let the sealer cure.  Only so much room in the garage and plenty of other things to do around the house.  I may be able to fabricate some of the next parts for the Horizontal Stabilizer but we’ll see.

This week I have limited time to work in the garage, but was able to make some progress.  While I wasn’t able to get video of it, I was able to prime the Spar,trailing edge, and the replacement striker plate this week using my Primer Pistol.  This was small enough job that I didn’t want to use the HPLV gun and it only took about a 1.5 film canisters to cover.

The timelapse picks up with me starting to dimple all the ribs, spar, and skins.  I mentioned in my Training kit that I picked up a set of the Cleaveland Tool SubStructure Dimple dies.  I used these on all my ribs and spars.  I’ll say that I am very happy with the results and how easy it is to rivet everything together as the parts sit flush.  I honestly haven’t tried to do everything with the standard die set so take my feedback with a grain of salt.  Dimpling all the parts was straightforward using the squeezer and DRDT-2.  The directions are already starting to be “less detailed” and don’t remind you what holes you should or shouldn’t dimple.  Lots of doublechecking the plans and sometimes flipping ahead to make sure you understand what you need to do.

I then start to rivet the nutplate onto the Rudder Horn.  I think I spent more time drilling out rivets on the nut-plate than it took me to actually rivet it together.  Hey, it happens.  No harm / no foul.  Just drill it out and install it again.  I’m getting much more comfortable with riveting and drilling out rivets now.

Out of all the work I did this week, my favorite is back riveting.  It’s just so easy, neat and very little chance of making an error that I absolutely loved it.

Completed everything up to 7-8: Step 1 in the plans and hope to get through 7-10 by the end of the week.
