One of the more difficult jobs is to locate and fix the front wing dowel that locks the leading edge of the wing,there is no really easy way of doing this but the following works well despite being a bit unorthodox-
Firstly drill oversize the hole for the wing leading edge dowel,place the dowel into the hole it will be sloppy,sand up some balsa dust and push this into the hole around the dowel so the dowel floats a bit,now place the wing into position and wiggle it around a bit so the wing seats properly with the correct incidence,now carefully remove the wing and place on to the trailing edge on your bench,now quickly flood the joint with the wing peg in place with thin cyno,there will be a quick puff of smoke as the dowel locks solid,and I do mean solid.
What has happened is the dust has become impregnated with the cyno,you can also use baking powder for this task but it is not as easy to hold the dowel in place,just be patient and make sure that dowel is accurate before you use the cyno.
If you can get to the rear of the dowel you could use this in reverse,but make sure you place cling film around the leading edge otherwise the wing will be glued solid !
