Build update: Reassembling the Aerovee Part 1 April 26 2018

The engine was all apart, scattered between 6 plastic bins of various sizes. 

The first step in my Aerovee assembly manual was to thouroghly clean the mating surfaces of the case halves, and file away any flaws from the manufacturing process. I used Laquer thinner, gloves, and a paper towel to clean away all the old sealant. And shook the shavings out.

Once it was stripped to bare metal, I moved on to the next step: I used engine assembly lube to goop up the various moving pieces inside the case, and the cam bearings. Then I test fit the cam just to be sure it turns smoothly and identify any problems before the case halves are sealed. Aside from getting molly lube on my hands from touching the cam without gloves on, it all went splendidly. The next step was to prepare the crankshaft's bearings, I cleaned, lubed, and fitted them. 

Now begins the fun part. Most of the bearings on the crankshaft go all the way around, and they can only do their job if they don't move relative to the case. To keep them from free spinning in the case, they have a indentation on the bearing, and a little peg (or dowel pin) that fits inside the indent. this means that when placing the crankshaft into the case, I needed to align the bearings so that the indents were lined up with the dowel pins. Big problem, you cant see the hole when it is straight down, so I was kinda working blind wiggling it trying to get it to pop into the indent. to solve this we used a pen to mark the bearing 180 degrees from the indent, now I just had to spin the bearing so that my mark was straight up, jiggle it a bit, and it popped right into place. Repeat a few more times and badabing badaboom crankshaft is in.

The big moment, joining the case halves! I opened my can of case sealant and painted on a thin layer, like painting an O ring into the case half. Up until this point I'd been only working on the right case half, it had all the studs in it. now it came time to carefully lower the left case half onto the right one. I lifted it up and slowly set it down the studs just barely poked through and I began the complex pattern of installing a few nuts torqueing them, and moving onto the next one, then torqueing them all down even more. after 10 or so minutes everything was tightened to full torque.

The next operation will be to install the cylinders.


(sorry about no pictures! It completely slipped my mind)

Build Update April 5 2018: Dissasembling the Aerovee

The engine I bought was already built, and had not been run. My dad and I planned to take it all apart to give me a better understanding of the engine, as well as to identify any problems before they got bad. The Arovee engine was heavy and awkward to move. at the time it was sitting on the workbench with everything installed. Going into this I had only enough sense to tell you which cylinder is the #1, 2, 3, and 4, and I knew some of the terminology, such as crackshaft. I frequently asked my dad "what do you call that part?"  we began unbolting stuff in roughly reverse order from the manual (if you're familiar with sonex plans, you're used to backwards) In under an hour we had stripped many of the external parts off and the engine had lost at least 20 pounds! A box was designated as the hardware box, so it'll be like legos trying to find the right bolts and nuts again when I reassemble it. the important part is that they're all together and no...

Plane Painted

When I flew my plane to OSH23, I saw an artist painting a small depiction of an airplane. She was painting a very small photorealistic scene from a phone image. I could not believe how detailed she was able to make it! She let me watch over he shoulder as she worked. I was so impressed that I commisisoned a similar painting of my sonex. Id like to share that painting with you all. Her name is Rhonda DeGarmo. She has a lot of other work. If you're interested in getting in touch with her please reach out to me and I will pass along her information.

Build Update March 15 2020: Prime Time

So everyone is kinda freaked out over corona lately. My gymnastics competitions have been canceled, and so have my classes. This has been great for building, I've got all week and maybe more to get some great work in.  I have been doing all the last things on the cowling before it's time to prime and paint. The final few things were adding my quarter turn southco fasteners, finishing the air exit cutout, and doing a final sand. (if you can ever even say final and sand in the same sentence) Then it's time to prime. The southco process started by going to southco's website to order an assortment of different sizes. When I completed my order the shipping cost came out to like $40, which was clearly wrong. I was ordering less than 20 studs. It would fit in a flat rate envelope easily. So I scrapped my southco order and went to Aircraft Spruce to order my cheese platter of sizes. The shipping there was much more reasonable and I combined it with some other items I n...
