Aileron – Leading edge – Scarfe joint

The leading edge ply for the aileron leading edge is 0.8mm so quite plyable … only problem is that it is just too short for the length of the quite large ailerons … this means making a scarfe joint to butt two pieces of ply together to make up the length.

 

Having read up on the internet exactly what a scarfe joint is … basically a layered joint to ‘blend’ one piece over the other. The internet was useful in that it gave advice on how your new joint was squared up … ie sanding using a hard block on the edge of a solid surface … then checking that the various layers (3 in this case) reveal in a straight line … then you know your chamfer is square
