      Mark- I'm still plugging away but since there isn't a storage facility this year I'm not so keen to bring the 'old timers'. All the nuts and bolts and struts and gap covers and screws... it's just too much to do twice a day for the event. Heck... at Horizon a gust caused the Eaglet stab to get a hole poked into it from a ball driver. I got a little miffed even though it is repairable. I'll have to break out the silk and dope!

      St├ęphane- met too but look at the comment above. I would like your assistance with an ASW20 and an ASG29. The 29 is a Robbe kit and has a 5m span.

      No problemo Mike, help you will have

  • More covering pictures. This is the center section. Again, masking tape put down then Stix-It put onto structure. Covering put onto this and tacked down with an iron at 200 degrees. More masking tape put on it to keep the Stix-It tidy on the fabric. The lower surface has undercamber so the ribs received adhesive and tape, too. After the Stix-It dried a sharp X-acto blade was used along the outer perimeter edges of the masking tape. Then the fabric was tightened with the iron. Once the other wing panels and ailerons are covered, nitrate dope then varnish will be applied.

        I have mahogany veneers 'in stock'! lol So how's the deck? Done? Still have vagrants 'camping out' on the furniture?

    • Phase 1 is complete, thanks for asking. No more 12 year old vagrant camping out.

        That looks inviting. Maybe I can be the next vagrant!

    • All the covering and nitrate doping is done! The fin was epoxied in place. A temporarily installed dowel segment sharpened in a pencil sharpener was used to locate where to drill for the peg that will secure the fin to the fuselage this end. Masking tape was used to delineate where Stix-It adhesive was applied. The bottom surface is concave so it is very important to get the fabric properly attached. The 'Dope Spreader Tool' is shown. Put a little dope onto the structure to 'prime', lay down the dope spreader tool then slather dope onto the tool as it is dragged across the fabric. The dope gets put onto the fabric really fast and none gets pushed through the fabric to pool. I put three coats of nitrate dope onto the model this way. Next to do is finishe the ply sheeting around the fin. Stay tuned!

        Tj- keep plugging away. It would be cool if you had it ready for NARCA.

        It surely won't happen this year. In fact, I may have to rebuild the Elevators. They're too narrow at the fuse to get full Down travel.

        TJ, these sailplanes' control surfaces don't need much travel.

    • Nice work Mike! Finish is looking great.

        Thanks, Gunny! I told my buddy about your PT-19. I'm trying to get some folks interested in sailplanes around here. I took buddy's Calypso glider and flew it for over 20 minutes without power. He was amazed!
