Thanks gentlemen - and thanks for the tip, Kitty!

Some progress was made on the right wing last evening. Having worked through some of my hang-ups and anxiety on this portion of the build, I suspect left wing construction will proceed a bit quicker and easier...

Thank you once again for the help and encouragement! It's been great fun so far and is becoming a bit...addictive.  Cheesy

Another way to do this if you cover dry, then shrink, is to pin down the wing to shrink with wedges under the trailing edge of the tips.  After you fix the tissue with dope or artist's fixative this stays just as though you built it in.

The wedges in the photo are 1/16".  The washout in the edge on photo looks bigger but that's all it is. I should have taken the photo with the wing sitting on a flat surface rather than holding it in my hand. Roll Eyes

After much to do...I might actually get a wing completed today...

Shown below is how I have the washout on the TE jigged. Any comments or corrections welcome.

Thank you!

Thank you, Tom! Seems like the obvious solution but sometime I suffer from analysis paralysis...Smiley

cut a wedge from scrap balsa with the grain running the length of the wedge.  Always keep some scrap balsa laying on the building table.  Be surprised how often this comes in handy.

Started working on wing construction today and ran into a wing tip fitment issue. As the wing tip meets the trailing edge, it's not square. I could try to sand it square, but then it may be too short leaving a gap. Any suggestions on the best way to correct this would be welcome and appreciated.

Thank you, Tom. This is something I need to learn to do so...I will plan on adding washout on this model as it should be relatively simple. Although I may post my "jigging" of said washout for comments before I begin gluing.

Much to do before wing assembling can begin, anyway. I best get to doin!

Thank you!

As you build the wing you might want to add the washout as you build.  Just slip a 1/16" piece of scrap balsa about and inch long under the T.E. from the tip in towards the root of the wing at both tips.  That way the washout won't be as effected by temperature and humidity if it's just shrunk in as you apply the tissue. Just an option.

Happy Independence Day, my fellow countrymen...

Just a couple of pics of progress...

Tail feather bones - salient data:

Each have a single coat of 50/50 dope thinner and a light sanding with 400 grit
Each are structure is running around .05" in thickness.
A second and final coat of dope and light sanding is next...

Wing construction starts next...

The final picture - which may not be appropriate for this thread - is a picture of a SIG Cub I built probably 10 years ago. One dewy morning I took out for a flight and the stab warped due to dew. I recently rebuilt it. I modified the tail feathers a bit and covered with tissue instead of silk span. One of my fliers for tossing in between building - a necessary activity to keep me patient while addressing the current build.  Wink

I've "tree'd" this poor bird twice. My local "Field of Dreams" is a tad too small after about 600 turns. Thankfully, it has survived the de-treeing process. I may take it to a park this week to let it really spread its wings.

Moving forward, any hints or suggestions on wing construction would be welcomed and appreciated!

Mark

Thank you, John - I will do so!

Thanks for the move, Sky9 - I suppose my original post has morphed into a build thread. Reckon I should share some pics to make it official.  Wink

Good idea.

Put on a coat of thinned dope and sand with 300-400 grit sandpaper then put on a second coat and gently sand with 300-400 grit. The smooth surface will allow the tissue to slide into place during application. That will reduce wrinkles and may help prevent warping.

The weight penalty should be minimal.
