Sanded and attached horizontal stabilizer tips

Sanded and fit the HS tip to fit. Before I paint the airplane, these will need to be filled and finish sanded.

Final drilled #30, dimpled the skins, and machine countersunk the tip.

I picked up a pneumatic rivet puller at Harbor Freight yesterday. I used it to set the rivets and attach the tips.  So much nicer the the manual puller!

This completes the work on the horizontal stabilizer and elevators. So I’ve moved them to a safe place until I’m ready to final attach them at the end of the build.

Shot primer this morning

I’ll be honest. I was dreading this step. I had never sprayed anything before. Turned out to be not nearly as bad as I thought. I didn’t get get pics of the process. Maybe next time.

My first attempt was on the practice project. Took a while to figure out how to get the gun set up. Shot way too heavy on the practice project. You can see how much darker those pieces are than the actual plane parts. I got it dialed in and I am happy with the result on the plane parts. They almost look like they’ve been anodized. They’re just a little darker and duller than bare metal.

The gun I used is a cheap touch-up hvlp gun from Harbor Freight. It’s perfect for the smaller parts and acceptable for the skins. I went with a narrow fan about 8 to 10 inches from the work with 30-40 lbs at the gun. I wiped everything down with lacquer thinner before I shot the primer. I mixed the P60G2 1-to-1.5 with the R7K44 reducer per the data sheet from Sherwin-Williams. The P60G2 was way more goopy than I expected. I was thinking it would be like paint. It was actually thicker and stickier. I wore a Tyvek suit, a 3M respirator, safety glasses, and nitrile gloves.

I bought an empty paint can at home depot that I am using to store and properly dispose of left over paint and solvent. I ran lacquer thinner through the gun and right into the can to clean up. It took about two ounces until it ran clear.
