I put retract servos in the wing of my short solent seaplane becausethe were short servos and then had to figure out why they would not center but only go up or down

I put retract servos in the wing of my short solent seaplane for the ail because they were short nice looking servos and then had to figure out why they would not center but only go up or down,DAAAAA ! then was spining my wing around while working on it and my ceiling fan took the winptip floats and float struts clean off . lmao The neighbors heard alot of foul languge that day !lol

I have come close to doing that myself a time or two. I started turning off all the ceiling fans in advance, its amazing how often I bump one repositioning a wing or fuselage.

As long as you can laugh about it then it's OK! Life is too short to fret about little stuff like that! Sometimes those little mishaps give you an opportunity to change something you wanted to do different.

Yes i dont worry about anything now like i did when i was younger . I fixed it and you cant tell the difference but i got loud when it happened .lol joe

Started on the fillet repair.

I have learned that with unpleasant jobs you just have to dive right in (helps to have a plan ).

The fillet didn't start to stray until about a 1/3 of its length back. So I cut into the fillet 3/4 inch from that point all the way back.



Then laid some wax paper down and taped a 1/64 g10 strip in place. The outer edge of the g10 will be the finished width of the fillet.


Then a layer of epoxy on top of the g10 and yellow glue wood to wood on the plug.



When that sets up it will be ready to reshape. The trick will be to sand down the top plane of the fillet 0 at cut in front to 1/8 at the back without gouging the fuse. Once that contour is correct, then sand the cove in.

Yayyyyyy .........

Fillet repair complete. Now I'm back to where I was .



Was impossible to sand down the top profile without some collateral damage to fuse.
That 1/64 g10 edge did not want to go away quietly. Used a profile temp to check as I sanded.

The offending fillet. (post op)



Now on to the fish tails.

Outstanding Kevin, and don't get frustrated, corrections are part of the process. Are you using a template to measure the radius of those fillets from one side to the other?

Looks great now KevenAs a carpenter i know how it goes to add plenty of wood then sand most of it off again to fill in things . joe

Nice fix Kevin, you would never know if you hadn't said so in the beginning. You do have a nice touch with sand paper, not to mention the rest of it.

Leroy

Melchizedek

Thank You Robert.
As far as the contours (front to back) I scribed a piece of MDF to fit the top of the wing. Then added 1 1/4 parallel to get the shape of the blanks. Both sides were cut with same template.

As for the radius of the cove. It is not a normal cove in that the radius is not 1 1/4. I wanted a larger radius to give more meat to the center of the cove. So I looked around the shop and found a empty cardboard tube to a roll of shrink wrap. It's about 4 1/4 inches.

With the G10 edges. I just sanded to the center. When the sand paper hit the G10 edge it would sing. When it hit both edges it sang in stereo. I knew to move on. Easy peasy. I used the whole roll when sanding off the plane. After my install mistake I couldn't use the whole roll so I cut a sliver and fudged it.





Thank you Joe

Leroy,
I used a permagrit slot cutter to pair down the high contour next to the fuse. I don't think any other tool would cut that G10 edge down in a manageable way. I have a corse one that I ca'd a temporary handle to. It took like what seemed forever. Anything else would have been 3 forever's, a lot of cussing, and a more damaged fuse.

On to the fish tails.

I figured out my vanishing point and cut a template that I thought looked proper. Given that when the fuse is apart for transport these fish tails are going to have points sticking out the side that could get wacked off or dented real easy. So I decided to make them tuff.
I had a hunk of 9/64 G10 that I decided to make the base out of. This stuff gets heavy fast the thicker you go, so I cut the center out and filled it with balsa.

I then cut a rabbet in the side of the fuse for the plate to set into.




The plates were then epoxied into the rabbit. Then balsa blocks where fitted and epoxied into place. Then It was all sanded to shape.





Still have to put some mini fillet in where the pointy tail meets the fuse. Needs a little blending.
All edges will get blended hopefully seamless after glassing.

Very good. We all find our way, I use dowels.

I have a 1/4 round permagrit sanding tool along with a 90 degree one with different grits on each side ,a flat one and a couple round ones . A builder friend of mine passed away and his wife called me up a couple months later and said her husband had left to me in his will and knew i would use them to build . Nice to have great friends like that and when i go i will pass them on to another builder and keep it going . joe

Melchizedek

Joe,
you were gifted a great gift.
The permagrit stuff is pricey. But almost every thing worth having is pricey.

Yes i know and i have looked at some of the new permagrit stuff after using mine i know they last forever and a great tool at their cost. My old ones have to be 25 years old and dont look like their newer ones .Merlyn showed me his new angled block one he bought and its next on my list . This summer most of my extra cash went into motorcycles and antique Cushman /vespa scooters so this winter i think its time to buy some more permagrit goodys ! lol joe

Leroy Gardner

Kevin I think you have been a help to a lot of guys. What I like about a good thread is the many ways we do things and the tools we use to do it, even the screw ups. Glassing should be coming up soon, ya think.

Leroy

Melchizedek

Thanks for the kind words Leroy.
Yes glassing soon. I do still have a few things I would like to tie up before I commence glassing.

I am going to hook up the Sub- D connectors for the fuse and the wings (I think). Hat tip Robert. Sweet Idea.
Also, building Top Notch engine and fit it in the cowl. Readdressing engine control linkage. Fuel line plumbing.
Landing gear completion. And a few other tasks.
