The glider fuselage has been wet sanded.

It's time to for final buffing.

I did some experimenting this morning to get a feel for process and especially process control.

I had two different polishing pads. Would they give different finish quality?

Would a grid of black Sharpie help me keep track of buffing progress?

(Don't worry about the Sharpie. It doesn't stain the polyurethane paint. I can wipe it away with a solvent like acetone.)

Either polishing pad gives similar results, and buffing until the Sharpie grid is gone appears to be a workable control technique.

Water beading on the buffed surface is another indication of progress.

On areas with complex, and especially concave curvature, I'll buff by hand.

I'm not trying to do a fantastic job on the fuselage, but I'll gain experience before I do the critical stuff: the wings.

The initial experiment setup. Two small Sharpie grids on the belly of the fuselage.

Buff one of the grids with one of the polishing pads...but don't remove all the Sharpie on the first grid....I was surprised that it didn't take that long, or that much pressure to remove most of the Sharpie grid.

Once I cleaned up this area, I saw that it had an acceptable finish quality.Here is another indicator of buffing progress: water beading on the surface when it's sufficiently buffed.Both polishing pads produced similar finish quality. 

I think the Sharpie grid is a decent tool to show buffing progress.

Now I just need to put in the hours....

The glider fuselage paint job has been scraped to remove drips and runs, and also to cut off the top of all the orange peel bumps that cover the entire surface.

I had to experiment with making a scraper tool. It required constant sharpening.

I have transitioned to wet sanding with a dual action polisher to remove the rest of the orange peel, but I had to experiment a bit to get a process and system. That's because I can't see the progress of sanding of a white surface that's covered with sanding water sludge. I will probably draw a grid of lines over the fuselage that allow me to monitor progress.

The final photo shows light at a glancing angle across a sanded test patch (fuselage belly...I don't mind screwing up here). I see no signs of orange peel, or larger ripples/waviness.

I think I can transition from this sanding job directly to rubbing and polishing compound.

Testing various pieces of hardened steel to make a scraper that removes the tops of all the orange peel bumps. Some metal could not take or hold an edge well.Glancing light shows that the vertical fin on the fuselage has been scraped all over. The tops of orange peel bumps have been removed.I need to draw black lines on the fuselage to easily monitor sanding progress. When the lines are gone, I have sanded enough.Low angle light shows a uniform surface with no small-scale orange peel, or larger scale waviness or ripples. This is a good sign.

I needed to mix a small bottle of nail polish to which I had added some acetone in order to thin the paint somewhat. This was a perfect job for my large paint shaker.

I needed thinner paint for some touch-up work at the exhaust port on the glider's turtle deck.

See next two comments to this post....

One 12-foot section (3.6 meters) of flaperon has been sanded, buffed, and polished.

Three more to go....

Flaperon? It's both a flap and an aileron.

The white flaperon, 12 feet long, sits on a padded work surface inside a garage workshop. Its white paint has been buffed and polished. An orange/yellow polishing rag sits on the flaperon. In front of the polishing rag is the drive horn that will be connected to a push-pull rod that is part of the flight control mechanical linkage.

The glider's horizontal stabilizer's paint needs scraping to remove runs and drips.

This part has a span of eight feet (2.44 meters). And I need to work on both sides.

Fortunately, the surface is convex, or flat in various locations...but it's happily not concave.

Setting up the work lights to give me specular reflections makes it easy to see and then work on the drips and runs.

I'm also learning that how I sharpen/sand the razor's edge (symmetric? asymmetric?), how I hold it (rake angle)...can make a big difference in how efficiently and effectively I can scrape away the high spots.
en.wikipedia.org/wiki/Rake_ang

The pile of shaved paint next to the razor was produced with one gentle pass...once I started figuring out sharpening geometry and rake angle. Before that, my progress was slow and required much more effort.

Glider horizontal stabilizer on sawhorses. A single edge razor sits on the stabilizer.Specular reflections show me many runs and drips that I will scrape down to match the surrounding surface.

(Reflections also show me orange peel...the bane of my existence.)Careful, gentle scraping can remove lots of high paint in one pass. The pile of shavings was made in one pass with little effort.Sanding/sharpening the razor-scraper. This is 400 grit sandpaper.

The glider winglets have been sanded and buffed/polished...well enough.

I did not use the polishing machine. These are small parts and somewhat fragile, so I buffed by hand.

The winglets have electrical connections (spring loaded car door jamb connectors, lol!) and a molded receptacle for these nav/position/strobe lights:

The 2nd and 3rd photos show a progression from ugly runs and drips...to a scraped surface that is almost ready for sanding.

#avgeek #aviation #ElectricAircraft #ExperimentalAviation #homebuilt

Glider winglets, buffed reasonably well.

They are removeable and feature electrical connections for tip lights.Ugly runs and drips on the paint stand tall in low-angle light.Scraping the paint with a single edge razor can smooth the runs and drips so that they stand only a couple thousandths of an inch (0.05mm) tall. Then they are ready for sanding for final smoothing.

friend Pholly on FA drew this randomly huh
