In order to attach the Flaps, we first need to (re)install the Ailerons, to be able to align the Flaps. Especially the lateral adjustment with the washers is important. Once the Aileron is set, I use an Aluminum angle to align the Flap. First I drilled the outboard and inboard […]
Finally found some time again to continue with the Flaps. After fitting, drilling, deburring and priming, I can now start with the assembly and riveting. Here’s the right bottom skin with the ribs riveted to the bottom skin and the bend in the skin that serves as the rear spar […]
While working on finalizing the wings, I interjected the work with preparing the flaps. Main reason is that for closing the wings, it is really handy to work with two people on it. So when my dad is not available, I work on the flaps. This results in about 7 […]
With the right wing closed, we now know tho “trick” and can do the left wing much faster. Starting on the inboard skin, working our way to the tip. On the inboard side of the wings are several ribs that support the “wing walk”. These ribs are so close to […]
Second session we spent on closing the right wing (bottom skin). Actually I thought it would take at least two more sessions, but during riveting, we kind of got the hang of it and increased speed. However bending over the wing and trying to apply pressure to the bucking bar […]
Before closing the bottom skin of the right wing, I found that the Flap brace needed to be countersunk. So we start with that, meanwhile my Dad worked on the piano-hinge of the Flaps, trimming them to the right size. With the Flap brace countersunk and spit-primed, we started to […]
With the Ailerons finished, I can now start with attaching, fitting and adjusting them to the wings. If you carefully place them in the outboard “bay” of the wing, it stays there, so you can attach them with the bolts. You have to make spacers from Aluminum tubes provided in […]
Riveting the leading and trailing edge skins to the Aileron spar is not easy. Probably the best way is a custom (formed) bucking bar, which I don’t have. I only have the tungsten bucking bar, which is really great, but lacks the ability to reach narrow places. I could reach […]
Last week I primed all the Aileron parts (on the inside) and wasn’t able to spend more time on them. Now I can start assembling the Ailerons. First step is riveting the stiffeners to the skins. This needs to be done before bending, or else there is no room for […]
I underestimated the amount of work with respect to deburring, scuffing, dimpling, countersinking, degreasing and priming. I thought I could do all this in one straight session. Especially priming is something I need to plan, because after that I can’t use the workshop for a few days (insufficient ventilation). It […]
