I apologize for not having any update recently. I have been hard at work with the school year starting for my kids, the yard work, and work obligations. I finally got some time to get outside and prepped the Horizontal Stabilizers. But enough excuses, back to the build.
I finished getting the spar caps cut and deburred. This wasn't too bad but required alot of drilling once done. I matched up the parts to the spar and started match drilling. A lot of the holes were not predone so it took a little bit of time. I got the flange done, removed them, cleared the piece, and then was able to get the web side finished. This was a bit tedious but was enjoyable to finish up.
Spar Cap Match Drilling
After the spar caps were finished up and drilled, I finished out the doubler drilling. This was rather straightforward, similar to the one on the Vertical Stabilizer. The one doubler was a bit stubborn to straighten out but I had it near perfectly straight when I finally finished up. The next part was to cut the horizontal spar attach brackets from same angle aluminum pieces. This was a bit of a complicated portion as you had to make angled cuts on a piece of metal that is hand measured and cut. The numbers were pretty precise and took awhile for me to get right. After getting these done, I had to deburr and round off the edges which took some time.

After the brackets were all done, I was able to finish up the second doubler and drill the brackets. The brackets get one hole drilled by measurement, and then they got match drilled to the doubler and spar. This wasn't too hard, but with three pieces of some thickness, I noticed the bit wanted to wander a little. I was able to minimize it and was happy with the final results. I utilized a trick from Austin Manke to lift the spar off the table, I had prebuilt the stabilizer stands from a later step while I waited to paint. This allowed me to lift the stabilizer and rotate it around, making it easier to work with.

After completing the match drilling, it was to to do everyones favorite part and disassemble and deburr. It took a little time to deburr all the pieces and holes, but its a rather straightforward task. Using the electric screwdriver, I was able to deburr a lot of the holes in short order. I used other tools for the lightning holes and edges. It was tough to deburr the spar lengths on the deburring wheel simply due to the length, but it was finished nonetheless. Then it was on to painting next, but a small project to finish first.
Once I finished the deburring, I was bothered by the way my Air connection was mounted. The connection drops from the ceiling and is screwed to the wall with some drywall screws. However, the screws weren't holding well and they were coming out of the sheetrock. This was bothering me and I didn't want to damage the air connection or wall further. I ended up heading to Lowe's to get a small board to reinforce the screws. I picked up some drywall anchors to screw the board to the sheetrock, and then screwed the air outlet to the board again. The wood was a perfect anchor point and it looks so much better, and isn't pulling off the wall anymore. Now we are ready to paint.

It took a few days for me due to the crappy weather we have had in New York Lately. But we finally got some warm weather on Wednesday which was just enough to prime and the winds were calm. So I broke out my painting racks and went to work. After I used up my remaining EkoEtch, it was time to get painting. I really like the Stewarts Systems products as they aren't extremely hazardous like others and simple to use. I got the painting done in short order and was ready to start riveting after lunch.
