A really productive day in the shop today. Managed to finish off the last flapperon (inboard right). A milestone part of my build is complete. Here is a family pic of them all together:
The opposite end shows the open ends of the outboard flaps (on the left below). This is where the aerodynamic tip inserts will go during final assembly:
With everything complete on the flaps, I stacked them up for wrapping in plastic sheet to protect them:
Once wrapped up tight, they go up in the barn for storage until needed back out for inspection and set-up on the wings. Stacked on some of my rolled aluminum, from botton to top, my completed assemblies are stabilizer, elevator then flaps.
One thing I want to try is 3D printing some of my parts and the aerodynamic flapperon tips are the ideal candidate for this technology.
I wrote previously in my blog about 3D scanning some original parts and using the 3D model from the scan to print them. I discovered that although my home server has enough processing power and memory for 3D scanning, the video card currently installed does not quite have enough chops for the job. A replacement I ordered arrived last week from Amazon and I set to the task of installing it. For some reason, the server will not power up (it has been sitting idle for a couple of months while I waited for the new video card). Bummer, I will have to investigate this further before I can start experimenting with 3D scanning.
Meanwhile, our local library allowed me to bring home their 3D printer. It broke several months ago and they have no money in the budget to repair it or hire someone to fiddle with it, so I offered to see if I could get it working. No idea at this point what it will take to get it working (it is an early model) but I told them in return for trying some prints from my 3D scans, I would both work on getting it working for them and pay for any parts that might be needed. From what they have told me, the extruder nozzle is clogged and the print bed may be damaged.
Very happy to have the flapperons done. Next on the build table will be the slats which I am led to believe is one of the more challenging sub-assemblies of the entire build. But that is what I got into this for - to learn :)
In an upcoming blog I document the 3D printer un-boxing, rebuild and repairs.
Thanks for following along.
