The 'What did you do in your workshop tonight?' thread

[stangflyer]

I am going to start with the control horn installation on the new left wing panel. First a little slice for each horn then a dry fit for alignment. First, the inboard...

 

[stangflyer]

And the outboard horns...

I like to remove the covering where the horn alignment plate sits. This allows the plate to be epoxied down and provides a good bonding surface.

I also like to lightly sand both sides of the horn shanks. Again, the epoxie bonds them to their perspective location like a weld on steel.

With the aileron control horn slots prepped, I will heat up the iron and iron down the covering just a tad before epoxieing in the horns.

First I fill the slotted cavities for each of the aileron control horn shanks, then insert the horns and push down to seat them into place. This is where the alcohol really comes in handy for clean up.

And now with an alignment dowel (small hex head nut driver) through the holes of each of the control horns, I will let them sit while the epoxy cures.

While the epoxy cures on the aileron control horns, I will open up the servo bays. I like to cut a "four cornered" angle so that I have enough of a lip to fold over so that the servo bay looks a little nicer.

With the servo holes drilled and hardened with thin CA, in go the servos and screwed down.

And with the servos in, tomorrow I will attach the ball links to their perspective control horns and program the servos for the new aileron.

If I have enough juice left tomorrow, After the connection and programming I want to address the extra length of the wing that does not match the original. We'll see how much steam I still have.

Tonight after work, I attacked the "extra" length on the new wing panel for the Edge. It was actually a lot easier than I figured it would be. Being the wing tip is a solid, (but very light) block of balsa with two wing tip ribs glued on then shaped. (The new wing panel was built with the option of the SFG's being used.) I started by warming the covering to peel it back so that I could work on the wing tip. Of course you all can see the difference between the two wing panels. Not so much the color as the lighting was different on the two photos, But more over the difference in length.

Once the covering was pulled back enough to work on the wing tip, I gently cut off the two outside ribs from the wing tip.


Once the outside ribs were removed, I did a little light sanding to the wing tip to obtain a perfectly flat surface. I needed to add back in a 1/64" balsa sheet to the wing tip then just a little light sanding for the correct length of the wing.

I will need to let the Gorilla wood glue set up before I cut and sand away the excess balsa sheet. In the meantime, I really needed to do a little cleaning and straightening. So I will finish the wing tip and lay back down the covering tomorrow.

Looking good Rob. Have you considered using the SFG ? I too usually just put them in a box to be forgotten but I actually tried them on the 330sc and liked them! KE and harrier wing stability was noticeably improved! To bad I had to go and break this one in half . The SFG's don't seem to work well there .
