Attached are pictures of what i completed yesterday on the Griffin


Yesterdays building day went by really fast, i almost CA'ed two of my fingers together when gluing wing ribs (1,2) together. I was trying to hold the pieces together as the CA set but in the process two of my fingers got stuck to the balsa, and then my fingers got glued together, lol. i ended up having to pull them apart before they dryed, it happened fast though, haha no damage to the wing ribs or my fingers lol but had me scared there for a bit.
Gotta be careful with that Thin CA

(1.) During this part of the right wing half construction you slide a scrap piece of balsa under the trailing edge sheeting and CA the rest of wing rib to the trailing edge sheeting. During this step its important to keep a weight across the main spar, such as a level or something so the wing stays straight and doesn’t twist or turn at all.

(2.) After step one you move to the front of the wing and CA the forward bottom sheeting piece to the bottom of the wing ribs. During this step it’s important to keep a weight across the main spar, such as a level or something so the wing stays straight and doesn’t twist or turn at all.

(3.)Another view showing how to glue the foward sheeting piece to the wing ribs using a scrap piece of balsa to get the foward sheeting to make full contact with the bottom of the wing ribs.

(4.) After completing steps 1-3 we will need to remove the tabs located on the wing ribs 1,2,3, and 4. These slots will later be used for the wing joiners. I found using a small saw from a hobby shop works great for this job. Cut on each side of the tab with the hobby saw and the tabs will come out easily.

(5.) Next we need to locate scrap 1/4" balsa sticks to fill the space inbetween the main spars of wing ribs (1,2) through (3,4) and wing ribs (3,4) through 5. After cutting the pieces to size, we want a pretty tight fit, CA those in place.

(6.) Another view showing the 1/4" balsa used to fill the space between the bottom main spar and the top main spar. Also shows the wing ribs tabs removed on wing ribs 1,2,3, and 4.

(7.) After completing those steps we want to locate a sheet of 1/16" x 3" x 36" balsa. This balsa will be used for vertical grain webbing inbetween the wing ribs. This vertical grain webbing is placed on the front and back edge of the main spars from wing rib 5 all the way through wing rib 16. Inbetween wing ribs 4 and 5 the wing joiner goes but to the left of wing rib 5 there is vertical grain webbing that is about an inch wide.

(8.) Proceed down the entire wing CA'ing vertical grain webbing on the front of the main spar and on the back of the main spar.
