The interior of N50KB’s cowl was starting to discolor from the engine heat. 8″ wide adhesive backed foil came from Amazon. After wiping the inside with acetone I found the wide foil wrinkled during application. It was cut into 4″ wide strips that worked much better.
Application Method: Cut a strip. Remove about an inch of backing. Align and start sticking. Grab the end of the paper backing from underneath and fold it back on itself while pressing on the aluminum side with a cloth. Slowly pull the backing while pressing with my palm. Follow the fold in its travel to the end of the tape. Burnish as necessary to seal any wrinkles.
Today, Dolly packed a nice lunch for us to eat during our two hour kyack paddle on the Homosassa River. (Where’s the Advil???) I took a wrong turn and instead of going to the Springs went past several waterside restaurants. We decided our food would keep; paddled back to the rental dock; drove to a restaurant; and enjoyed “Chowda”, hush puppies, fried grouper and cokes. It was great!
Social distanced of course. The breeze was coming at us from the river.
Dolly and I flew down to Sebring this morning and had brunch on the restaurant porch with the Old Farts Flying Club. The club is an informal organization run by Roger Brown who maintains an Email list and chooses an airport restaurant for lunch each winter season Thursday. He follows up with a newsletter including photos of participants and their planes.
Today’s weather – strong crosswinds – reduced the attendance. Before Covid I’ve seen fifty to seventy planes fly in. Today we social distanced and masked. Dolly and I arrived early and picked an upwind table. The food, omelet and pancakes was delicious.
Considering there has been no formal advertising, sales of the aircraft Ignition Wire Guards is growing nicely just by word of mouth.
Until now, the only DKFL product available has been Guards for amateur built aircraft having four cylinder engines with automotive eight millimeter diameter ignition wires.
Currently the store is building inventory of Guards for five millimeter diameter ignition cables used with Slick and Bendix magnetos. Also, the product line is being expanded to include Guards for six cylinder engines in Amateur Built aircraft. They will be available in six colors to blend with engine or air baffle colors.
Today I finally organized the area where the aircraft Ignition Wire Guards and other parts are printed. The overhead filament spool rack is new. The 1/2″ PVC plumbing tube is sagging a bit under the weight of the filament. I may insert a metal rod reinforcement.
Its a ten gallon recirculating system currently holding two 60 day old bell pepper plants. The tray has a 3D printed bell siphon with about a 15 minute fill/empty cycle that changes the water level by 1.5 inches.
The peppers have much larger leaves than those growing in our tower, and there are no insects eating holes in the leaves as did those in backyard milk bottles. There is some red algae growing inside the sunlight exposed nutrient recirculating tubes. Next winter I’ll use black vinyl.
Worst Case: We are going to be in this for a long time, so be prepared. The mask-in-stores requirement will go on for months as the ramp up for the second wave occurs next fall.
Dolly and I have a handful of N95 shop masks left over from building the airplane. They have been used during trips to grocery stores, etc. We expect them to become contaminated, and they get set aside after one day’s use.
I found DIY advice on building a UV-C sterilizer on YouTube. The sterilizer uses a 30 watt Phillips UV-C bulb available online.
Note: UV-C is the far (short wavelength) end of the ultraviolet spectrum. Brief exposure is said to cause eye damage and skin cancer. It’s not the UV-A/B ultraviolet spectrum used to light up fluorescent materials. The light intensity will sterilize anything in the box in five minutes.
Dolly contributed the wooden box which was made some time ago by her late husband Al’s uncle Edsel. I wrapped Reynolds foil around quarter inch foam board and stuffed it onto all interior surfaces of the box. The shiny foil ensures the light is reflected onto all surfaces of anything in the box.
Masks are held for sterilization on 3D printed frames. Each frame is composed of five parts that snap together solidly. Lucky we have a printer! I found the design for the frame on a medical website.
Family and friends who need masks sterilized are welcome to use the box.
Pilots flying under instrument flight rules (IFR) make a practice of recording instructions from air traffic control (ATC), usually with pencil and paper. Pity the poor pilot who lost their pencil to the cabin floor and can’t retrieve it because the seat belt and shoulder harness are tight and the plane is flying through turbulence while ATC is issuing an amended route clearance.
With a 3D printer and idled hands I made a solution for Van’s RV aircraft.
The blue double ended thingy sturdily clips onto both the plane control stick and standard sized pencils.
I’ve started giving them to other fumble fingered pilots.
You know who you are. Just ask the next time we see each other.
For RV deprived pilot friends, I also have a version that clips onto standard aviation chromalloy 3/4″ tubeing.
“Rowan University engineering and medical students have developed a prototype for a durable, lightweight, reusable face mask to augment the supply of face masks during the current shortage…”
“The prototype provides two components: a contoured mask and filter housing. No special tools are needed for assembly. The replaceable nonwoven filter materials recommended for the filter housing are widely available. Users will supply and install the elastic or cord.
The mask can be printed in three sizes, all with the same size filter housing. The contoured mask may be more closely molded to the user’s face by submerging the edges in hot water and pressing it to reform the shape against the face.”
The website has detailed instructions for printing and using the masks.
I have printed several of the masks in both polylactic acid (PLA) and acrylonitriel/butadiene/styrene (ABS) plastic. Dolly and I have each tried the masks. Of the three sizes, we prefer the small . When printed in PLA the mask can be softened in hot 140 deg. F water and then molded to the face for a perfect fit.
It was forecast to rain today. So, I harvested these from our hydroponic garden. I should have placed a ruler in the photograph. The central tomato is about 3-1/2 inches in diameter. Add lettuce, raisins, craisins, dried cherries, shredded cheese and salad dressing. Yum…. Eat Healthy. Next week I’ll put on a mask and gloves to go grocery shopping for several head of lettuce.
