Pic 1 shows the wing laying on the balsa sheetingI am getting ready to cut the sheeting to size and I am allowing 1/4 inch overhang on all sides.
Pic 2 shows the cut sheeting and notice how I labeled everything? These wings look the same top and bottom but there is a true top and bottom. I thing its a good idea to lay some cling wrap down to protect the shucks and to keep the wing from sticking to them.
Pic 3 & 4 shows the sheetingand some more labeling
Pic 5 shows the wing fully guled and sheeted on both sides and placed in the shucks with 30 lbs of weight to sandwitch everything in place. Now lets talk about how I got to this step.
After I cut the sheeting to the size of the wing with a little overhang >NOTE< ( On the first wing I allowed 1/4 inch overhang all around I found this to be the minimum overhang.On the next wing I allowed 1/2 inch. This is better) I used Gorilla glue and with a plastic card I spread it real thin all over the sheeting. Then rubbed a wet towel over the wing itself. placed the bottom sheeting in the shucks then placed the wing on top. I spread glue on the orher wing sheeting and dampened the top part of the wing. Place the sheeting on the wing and make sure you have the correct amount of overhang. Place the top shuck down over the wing and add the weight to hold everything in place.
When you fool with Gorilla glue the stuff expands a bunch so you need to allow for this.I had 30lbs of weight to hold a 34 inch wing down and this stuff was powerful enough to move the wing off the sheeting. You have to keep an eye on it and reposition the sheeting on the wing. This glue does not take long to set up to where it will stop expanding. 30-45 min depending on weather. Here in Tennessee its real humid so this glue expands alot. Keep an eye on it!!!!!
