Brief Description: Powder Coated Tail Spring.
|
|
There are several parts on the plane that I would like to have powder coated because I like the durability it offers. I have had several parts powder coated for past projects, and expect to in future projects, so I decided to make an investment in the Eastwood DIY powdercoat system.
I purchased a used oven off craigslist for 50.00. It had a front glass, but the thing actually tipped over in my pickup on the way home, which broke the glass. Nevertheless, it still works for what I need it for.
I am wanting to get my fuselage off the rotisserie as I finish up painting the fabric parts, so the tail spring was my first opportunity to use the system.
It turned out to be really slick. After a light sanding to eliminate any rust, and cleaning with the Eastwood pre-prep, I hung the part from the oven rack which was mounted in an Eastwood painting stand. With the ground lead attached I blew powder onto the spring. I had an area that was not dry after the pre-prep cleaner, so I blew all the powder off the part, re-cleaned, and reapplied the powder.
Then it's in the oven at 450 degrees until the powder flows to a gloss (about 20 - 30 min), then let it bake at 400 degrees for 20 min, followed by a cool down for about 45 min. -- Thats it, and it came out excellent.
Clean up is piece of cake - Just blow the gun off and vacuum up the excess powder from the floor.
