Quality Control at Boeing

Prime-a-palooza

After what I thought was enough deburring (more on that in a bit), I started priming the shiny bits.

The rudder has significantly more components than the vertical stabilizer, which resulted in a number of rounds of priming.


Finally, I was able to start dimpling the skins, which was oddly satisfying

Anticipating some flush riveting in the near future, I finally sanded the Avery swivel set so the AN426 heads don't sit proud to the skins.

First Big(ish?) Mistake

So Flight Chops has a new video out about his build!  He seems like a good guy, but honestly I feel like his videos make building seem more daunting than other channels set up specifically for building.  This is primarily because Steve seems so overwhelmed by everything, and he appears to be leaning pretty heavily on experts.  This is compared to Jason Ellis' channel, where he shares not only the build process, but the process of learning, making mistakes, and resolving issues.  Seeing Jason make mistakes, reason out his resolutions, and share encouragement with the audience makes me feel like I can build a plane too!  Full disclosure, I gave him my Vans' finders fee for his channel.

On to the mistake!  Steve's build seems to be taking an interesting tact, instead of deburring, drilling, deburring, priming, and riveting, they're deburring everything from the start.  Watching the process, I thought to myself, "Huh, am I deburring as thoroughly as they are?".  In short, no, no I am not.  I thought this was pretty ironic, as I had just had a conversation about the quality control issues at Boeing lately.  Glass houses and stones I suppose!


So, I'll reach out to the gurus at VAF for their opinion.  However, it appears I may need to drill out all the rivets I've set so far, finish deburring, some components, and touch up the primer with another coat.

To make myself feel like I got SOMETHING done, I deburred a HS doubler to compare against a raw HS doubler.

 Finally, I countersunk the trailing edge wedge (scrap pictured) and test-fit it in the skins.

Off to the Races

Vans Practice Kit and Starting the Vertical Stabilizer: Every year, gearheads from around the world congregate at the Circuit of the Americas track for Moto GP.  My best friend, being one such gearhead, came to Austin to enjoy the races and experience the area.  While he was here, we ended up heading to the hangar to try our hand at building some airplane (practice) parts.  We ended working through to step 6 of the practice kit, attaching and match drilling the skins to the 7 before it was time to head back. The following week, I spent a few hours making some more progress on the kit, rounding out the build by wrapping up just before riveting the flanges and trailing edge. I also ordered a few more parts, and finally embedded a back rivet plate into one of the workbenches I've been holding off on picking up a back rivet plate only because I hoped I could source a cold-rolled steel plate locally.  As it turned out, the ease of simply ordering one ...

Finalized Shop Setup, Built a Toolbox

Image
Finished shop setup... for now: My hope was to have completed Van's toolbox project last week, but getting all the bench tools assembled, mounted, and tested took longer than expected.  Much like the week before, the only productive day this weekend was Sunday.  After picking up a bench grinder, and assorted mounting hardware, I made my way to the hangar.  I started by assembling and positioning the tools where I thought they would be best placed, and then traced out and drilled mounting holes for each.  I then tested each by powering them on and waiting for the explosion. I must have spent an hour figuring out how to set up that band saw. This time around, I thought I would experiment with a time-lapse setup with my old GoPro.  I was able to record the entire session with a new 128GB card, and I'll edit and upload it to YouTube when I get the chance. Built the Van's Toolbox Kit: Confident that I wasn't going to lose a finger to the band saw u...

An Air Show and Some Tables

Inventory Finished: Despite diligently getting my flu shot this year, someone at my office brought in a case of the flu. A lazy day of cold medicine and soup warmed me up and set me right, so off to the hangar I went. Skins, spars, and rivets oh my! A few hours later, and after shooting the breeze with Mr. Peck, who deserves an introduction at a later date, I was able to finish the inventory process.  According to Vans, I’ve got all the bits and pieces I should have. EAA Fly-in and BBQ: One of the perks of slowly becoming an airport bum is that I get to experience the local airport fare.  This weekend saw beautiful weather, Texas BBQ, and the smell of avgas.  It was a great time, and an excellent opportunity to rub elbows with other builders and enthusiasts. A real life VeriEze! Wouldn't be an air show without a Stearman! Last but not least, one of many RV's Finished with the Carpentry (for now): After recovering from a busy week, I spen...
