For all that have asked sorry for the delay but I finally got around to building alother biplane and making detailed pictures on how i have been stringing them. Each plane is a little different but the basics are the same. Once you get the hang of it, It only take about 1/2 hour to do one.
This plane is buzzbombs biplane. I scaled it up to 150% hoping the pictures would be more clear.
steps
1. I start by just running the tip of the glue gun along the edge of the foam on all 4 struts (4103) This put a nice radius in the foam for the skewer to sit it. Then glue the braces in place and run the skewers through(4104). then pull them aside and, run a bead of glue down the groove and glue the skewer to the braces. (Pic 106).
The needle I'm using is just a 7-inch piece of push rod with a loop soldered on one end. I used thin rod so it will bend as I need it. (4107)
2. Now I poke a hole both front and rear of each skewer, both top, and bottom. Total 32 holes. (4117)
3. Do not glue anything yet. Start out by running the thread through the fuselage front bottom right at the skewers (4109), pull enough string through to go completely around the plane. Then proceed to thread the string around the skewers at the top wing (4112) leaving the string loose for adjustment later. Then back down and through the rear fuselage again at the skewers (4116), then up to the other wing, around those skewers and back down and through to the front fuselage again letting both ends hang loose (4121).
4. Now at the REAR of the fuselage, place a spot of glue on the string at each side (4124). now the center of the string is anchored you can pull either the left or right string tight to get the center of the top wing in line with the rudder and centered. Dont worry about the leading edge of the wing yet. Just align the trailing edge to center and put a spot of glue on the outside edge of both skewers. (4125). Now just pull the string on the other side taught and glue it the same. Be careful not to pull so tight you move the rear of the wing off-center but still, it needs to be tight.
5. now that the 2 rear strings are done and all 4 spots at the top of the wing are glued now you can pull the strings tight at the front bottom fuselage and use them to take any twisting out of the top with and make the leading edge align with the trailing edge. (4122). Once you have that I just tuck about an inch along the wing on each side and glue it in place. (4142)
Now for the second string.
6. Again I start at the front top. I run the string straight through the first strut but then put a loop in the second strut. (4146) again allow enough string to go all the way around and do not glue anything yet.
7 run the string again around the skewers at the bottom of the wing (4144) and then back up to the rear top wing. BUT here you need to put a loop around both skewers loosely. (4148).Then again around the skewers on the other wing working your way back to the front.
8. back now at the front top put a loop around the first skewer and then straight through the second. (4149). now you can cut the string from the spool and just let both front pieces hand loose. (4150)
9. starting at the rear of the wing again glue only one of the two loops in place and let it dry completely. Once that loop is dry the pull the second loop and the string between the two loops tight and glue that loop to the skewer. (4153). This not only stops the string from cutting the foam when you pull it tight, it also pulls the seam of the wing together instead of apart.
10. now as before just pull the string tight working your way on both sides back to the front. gluing only at the outside braces, not the center two just yet.
11. Once back to the front top center , use the piece that hanging to pull the loop and string tight and glue the loop in place then once dry run the loose end again about an inch up the brace and glue it down just add a little extra support for the loop, and to tie up any loose ends. (4158)
12. repeat step 11 on the other side.
13. Sit back and admire a job well done. (4161)
