After building two extremely scale sailplanes it's time to start what might be another. The airframe is 1/3 scale with a wing span of 199.8", as for what it will be, it follows a numerical sequence. Being in the early stages it will sprout wings someday with a 18.64" root chord and a 7.324 tip.

Don't you wish you could fly them without having to cover up such beautiful structure?Originally posted by Gene C View PostComment

With the fuselage stringers installed and turtledeck fitted the old girl has nearly doubled in girth now. The nosecone has been set and with some whittling for the tow release and forward skid mount the nosecone just needs finishing along with a lot of other parts.Comment

Progress continues on the scratch build Bunny Nose LK-10A with a little snag. Cardboard templates were cut and fitted for the wing stub section with the other side yet to be done. You can get to a point that you loose momentum, so a step back to see what you have done and with the help of some masking tape where it has yet to go rejuvenates the building process .Comment

That's beautiful! Love your fuselage, again very scale like...Gunny

The other day while working on the leading edge sheeting, there was time left to finish up the spoiler levers. Must say it quite enjoyable. Also stained the inside of the rear seat wing area as it will be visible from the rear seat and lower wing windows.

Before working on wing fillets the fuselage stringers were given a Amber hue. The wing fillets are in a process of experimentation at this time while working on the total fillet effect assembly. Most likely an epoxy glass form from the wing tube to the trailing edge. This may take some time to workout though as nothing is in concrete when scratch building.Attached FilesComment

The fillet bucks started off well but just when the first attempt was ready to mold a new in depth photo was sent to me. After communication with the two LK owners it was necessary to make some modifications, as the LK in the photo and the one I’m using for scale (bare bones at this time) both have extremely large wing fillets. Nothing that filler, epoxy glass, more filler and paint could not cure, plus a generous portion of time. Finally it was time to mold the fillet bucks so two days in preparation plus four hours of intense epoxy work left only an overnight wait to see the outcome. Prefect, NO but with only a few voids to fill, a most satisfactory outcome. Now the upper wing substructure in the aft cockpit can be removed, lower wing surface with window and molding of new wing fillet panels can be accomplished.Attached FilesComment

Yup, they do require a huge amount of time, but looking at all your efforts, they sure look fantastic!Gunny

It was inevitable that the LK build would come to this "WINGS", the least enthusiastic part. The main reason is that you have just finished a 92.8" wing panel to turn around and build another one "exactly" like the one you just finished but opposite. That said you have to start the wing process somewhere and that should be spars. Over the years a few methods have crossed my way to make the spar lamination a little less messy. Starting with and easy to made epoxy spreader to apply and even amount of epoxy to the spar surface and a syringe to apply a bead of epoxy to the spar surface before spreading. Of course a flat building surface, an aluminum channel and plenty of clamps helps immensely.

Does sprouting spars count? Wing ribs are ready for assembly but there is some work to be done on the spars yet. Charley my shop cat is bored to tears just watching it seems.Attached FilesComment
