The blue protective cover started to pull away so the dark blue tape is some fine line masking tape to hold it down. I got tried of the hand Deburr and wrapped some masking tape around the threads of the deburring bit to protect the threads and put it in my rechargeable drill, it go much faster with a light pressure.

Dimpled the VS skin using pneumatic squeezer on the edges ands C frame on the inside holes

Used some cut up coat hangers to hold the parts while I primed them.

Tape 12 AN-426-AD4-6 rivets in the holes at the bottom  of the spar and back rivet the VS-808 to the VS-803

The 12 rivets back riveted, the other holes attach the VS-410PP and require a AN-426-AD-7 rivet and are done also by back riveting

I used the Longeron Yoke to squeeze the rivets along the spar. It allows you to reach over flanges better

Assembled skeleton and riveted it together and shot a final coat of primer over everything, hung it on the jig plumb bob cable to dry.

Finishing edges using pneumatic squeezer. The arrangement of the spar being clecoed to the hinges on the jig makes it very easy to rotate the piece into any position and makes it easy to find the best position to work on it. The VS is turning out very nicely and looks good, the learning curve is working and it was much easier to do than the HS. The feel and sounds of the rivet gun are becoming understood.

Though I didn't see this on the plans it was suggested from the Orndorff video you may want to install some electrical things, like a strobe light on top of the rudder, install a couple on snap plugs and a wire or string inside that runs between the top and bottom rib, so you could use it to pull the electrical wiring after the skin is riveted shut. I just used some dental floss left over from the jig rigging.

Small mistake punching extra hole in skin! No problem with this metal colored epoxy filler, which looks like aluminum paste, just add catalyst and mix well.

 I accidentally punched a small hole in the skin while dimpling, time to drag out the Bondo. Actually there are some very good catalyzed fillers if not applied to thickly. I remember using this one called metal-2- metal back when I was building Porsche fenders out of the stuff in my auto days. Make up some little cardboard pallets and mix a small amount putting a little catalyst  in and mixing well.

November 23, 2001

Use a spreader( I just used a little 6 inch steel ruler that was handy and cleaned it good after) and fill the hole

 

Apply thin coat and it will fill hole and will sand lightly later

Bucking rivets in hard to get to places starts to become a challenge to find the right bucking bar. I searched my tools and tried these Chisels, they fit in some tight places and you can use the  machined surfaces (being Snap-On) which has a nice finish and they have some heft to them and seem to work well after you move them around a bit to get used to them. Inventing tools as you go can be fun. I would be glad to start a Tips for Tools page to the site if any of you out there have pictures or diagrams of things that you have made and have worked for you. Email them to me at mikemb@aros.net

The final rivets in the VS. Again having the piece in a jig where it will rotate around to different positions and getting the work where you have good access is much easier than being a contortionist bending around ,kneeling down to get at things. It is easier to do a good job when you are comfortable. I move the work in several different positions to get the best access. I find sitting in my little scoot around chair  puts me in a good place and height a lot of the times and sure saves the feet.

 

Need to have a little ceremony marking the last rivet on the VS, actually not the last because you were supposed to leave 6 on each side of the bottom rib to attach the fairing later, so this picture might be to late, get out the drill.

Here it is "stabilizing" the work table, it sure is pretty!
