Vertical Stabilizer

I kept working on my horizontal stabilizer for a while after my last post. The work I did was OK, but I kept getting the feeling that I could do better. Past Sunday I woke up and decided to just order the couple of parts I needed to re-do what I did not like.

While I waited for those parts to arrive I started to work on the vertical stabilizer. I read many times that this is actually a better sub-assembly to start with, and I have to say that I totally agree. It took a lot less time to complete. The VS is a pretty simple to assemble part. I matchdrilled, deburred, dimpled and primed in the same way that I did in the past.

The hardest part for me is definitely using the rivet gun. I managed to only put a couple of small smileys o the skin (but I still feel disappointed about it, even though everybody says that is normal). I’m thinking about getting a 2X gun to complement the 3X I have to test if the results are better.

Priming the parts this time went a little bit better after I got a new gun with the right size nozzle. There is still room for improvement, and definitely I’ll need to build a paint booth to help with the mess.

I’ve been using the Stewart Systems Ekoprime Primer. I really like that is not hard to deal with it as it is a water based primer. I’m sure some other products may offer better protection, but I do think that what I’m getting is enough for this project.

Next I’m planning an redoing the couple of parts in my HS and finish it. After that I think the rudder may come next.

Horizontal Stabilizer – 2

After looking at VAF Classifieds for weeks I found two of the tools that I considered a must have: DRDT-2 and Main Squeeze model 22. The first one required a quick trip to Middland, TX, and was quite an adventure to take it to Dallas. The second one was a cool find that a gentleman was selling in South Texas. For everything else I needed to start I gave the awesome people at cleaveland aircraft tools a call, and they customized a kit for me. At the end I basically got everything they offer in their get me started kit, plus some aditions and substitutions I deemed appropiate after taking the fundamentals class at synergyair.

Because I took the time to prepare the ribs, spars, doublers and also build the shims and angles I needed I was ready to start assembling the horizontal stabilizer. The first steps of instructions went pretty fast.  I match drilled the structure, and now I’m at the point in which I need to disasamble, debur and get ready to match drill the skins.

Horizontal Stabilizer – 1

The past two weeks I’ve been working on the last few details before I start building. I spent a couple of days making one more table that I should be finishing soon. I also built a small one to install my drill press and grinder.

Working on building one more table

Regarding tools the idea is to get a basic kit from Cleaveland Aircraft Tool and keep adding more as needed. I’ve been looking around to buy some of the more expensive tools used, and already have a list of what I may add in the near future.

Having the parts home and not being ready to work on them has been a little bit hard :). That’s why at least some preparation has been going on. I started to prepare the front and rear spars, duoblers and ribs. I also fabricated the HS-908L&R. Not a lot, but enough to keep me exited.
