Merry Christmas to all. Before the holiday I got the wing flipped and heat smoothed all the tapes on the top side. Then I sprayed the 2 coats of poly brush on about a day apart. I sprayed the first cross coat of poly spray, let it dry for a day, and then sprayed the 2nd cross coat on the top side of the wing. I let this dry for 2 days and then wet sanded with 400 grit and scotch brite pads, and finally sprayed the 3rd cross coat of silver.
I do all the work right there in the shop. It is a 2 and 1/2 detached garage behind my house. I have a filtered exhaust fan at the rear wall and a filtered box with a fan in the center for filtering the air and a screen for the man door. Using a HVLP gun and spraying at about 16 to 20 PSI the over spray is not that bad. Yes I do get build up on everything over time but dust and other stuff from grinding, wood working, and everything else too. About every year I clean the entire shop and power wash the floor. Its a good excuse to go through everything and toss out junk and organize. I finished the bottom with poly spray, wet sanded and sprayed the last coat of silver. Waited a few days and sprayed 3 coats of Daytona white on the bottom. I let this dry for a few days and flipped it over and sprayed the top 3 coats of Daytona White. Gave this about a week to dry and then taped off the leading edge for poly tone true blue.
Beautiful work as usual!! I have just ordered all the fabric and supplies, but they were out of stock of the Poly Spray. The recommended amount at Spencer is 10 gallons of Poly Spray, which seems like way too much. How much Poly spray did you end up using?
Yes, 10 gallons is way to much for this size aircraft. I used about a gallon and half per wing. About gallon for the 2 ailerons and rudder. Still got horizontal stabs, elevators, and fuselage to go. Approximately 2 gallons per wing for poly brush, you use more of this by putting down finishing tapes and brushing it on. I used about a gallon per wing of poly tone.
There was finally good weather to move the wing out of the shop and to my hangar, it was either to wet, to salty, or to snowy. Plus I had to let the back yard dry up to get to my trailer. I painted the last of the interior panels above the doors. Next I made up and welded together the two aileron stops. I cut out window openings in the inspection panels at the aileron cable connections near the wing roots. Also I made up the two steel straps for the tie down rings. This was all cleaned up and epoxy primed, along with the lift struts.
Not much of a update, I've been getting some home spring projects knocked out. I did get enamel Daytona white sprayed on the lift structs, aileron stops, wheel covers, and a few other inspection panels.
Finally got the fuselage back into the shop. The first thing I did is fix a few mistakes. The U channel above the D window was attached to close toward the inside of fuselage. So I ground down the welds and moved it outward on both sides and welded it again. The issue was when I would put the D window and trim on I think it would have been interfering with the wing root fairings. The other thing was the U channel at the elevator attach was to close together at the tail post and was just touching the elevator tab at the top that connects to the spring on the cable. I ground out the welds and moved both of them outward about a 1/4 inch each and welded them again. Everything got epoxy primer after. I installed the last of the rivnuts on the U channel for the wing root fairings and attached all the tinnermans to the tabs for the interior panels.
