Default VS "done" as far as Canada allows

November 4: riveted the VS skin to the skeleton. I wrapped the tungsten bucking bar in hockey tape to try to keep the scuffing to a minimum. Got it all completed in one session. All but the front two rivets on the VS-706 tip rib. Thereís no room to get a squeezer or bucking bar in there, so it looks like Iíll have to fabricate something to be able to get those last two done.



And the rear spar is clecoed into place for now. Because Canada requires a pre-closing inspection, no parts of the structure can be enclosed beforehand. So Iíll have to leave the VS (among other parts) incomplete until I get enough done to have the inspector come out. This would probably include the VS, HS, possibly elevators and rudder, wing bottom skins and the bottom of the fuselage under the floor panels.





Some blue masking tape on the flush set makes quite a difference in reducing marring. I got about 20 rivets out of one piece of tape.

Your level of attention to detail is going to serve you very well throughout this build. Looking terrific so far.

BTW if your MD-RA inspector is reasonably local, it can be quite worthwhile to have your inspector pop in for a progress inspection if you are ready to close up the tail pieces. That way you can get sign-off on those items, finish them and have the satisfaction of having fully finished parts that will be ready to hang on the airplane. I know MD-RA charges for mileage, but if your inspector is close it might be worthwhile to pay him the going rate for a quick visit.

Thanks for the feedback! Unfortunately he's a couple of hours away.

Default HS Done

At least as far as I can go until the pre-closing inspection:

November 9-16: After clecoing in the 905 nose ribs, I riveted them into place. Then the completed front spar/interspar assembly was put into place and clecoed in. Skipping every other hole, I still managed to run out of silver 3/32″ clecoes. I ended up working from one side to the other, moving clecoes to the other side as I completed a section.





Once things were clecoed into place, I began riveting the skins to the flanges of the front spar, then riveting the skins to the interspar ribs up to the stringers. Then the skin was riveted to the stringers on each side, then the remaining ribs were riveted to the skins. I used the tungsten bucking bar and flush set on the rivets that I couldn’t reach with the squeezer.

I had to drill out a couple of rivets whose shop heads were overdriven and flattened out. And looking back, I should have started riveting the skin on the bottom side of the HS, as the first part of the rivets set resulted in some skin “lumpiness” that I’m not too pleased with. The second side turned out better once I had more practice.

I did finally get in contact with my assigned MD-RA inspector, who informed me that every rivet must be visible in response to my question of how far could I assemble. So again, I will leave the rear spar clecoed into place, and the two inboard HS-905 nose ribs will be left out to allow a clear view of rivets in the front of the horizontal stab. So for now, I’ve put the partially completed assembly on the shelf, but will finish the front spar to nose rib blind rivets once I pick up my swivel nose rivet puller I ordered from Aircraft Tool. There is simply no room for a regular rivet puller when trying to pull those dozen rivets.

On to the elevator next. I will be travelling to Colorado for work starting tomorrow, so I'll be packing the first batch of elevator parts, some sandpaper and my deburring tools to work on in the hotel. No sense wasting downtime in a hotel.
