I begin by enlraging the flaps pushrod hole. This is the result after some iterations, extensions and retrations of the flaps.



The flaps is rubbing aginst the fuselage, so off come a few 1/16". In the retracted position it touches the step welding, so I file the welding.



For the opposite pushrod, things are easier. Just make a template, makes some marks to get the correct position (the crosses are over rivets), turn the paper and you are done. Then I mad a conservative cut and after two samll adjustments I'm done in a qurter the time.



The flaps fully deployed.



The the ailerons are installed. During wing construction, the flaps the ailerons and the wingtips were perfectly aligned. I'll use this to rig the ailerons. At first the ailerons are slightly misaligned.



Once the ailerons, the flaps and the tips aligned, I tweak the pushrods. On the left all looks good. On the right, the flaps is slightly lower that the fuselage that it's supposed to hug. I leave it that way as the installtion is not definitive and there are some minor plays to take out of the system.
I'll also check tomorrow that my flap is straight.

I begin by drilling the rear spars, I can walk the one hole slightly inboard and everything seems to look good.



Then I drill the fuel tank bracket. The bracket on the fuselage is slotted to allow the tank to be ripped of the bracket rather than teared open in cas of mishap.



Then I fabricate the fuel and vent lines. On the left side, one fuel line for the moving pick-up and one vent line.



On the right side, only the vent line. The fuel line will be cut 3 3/4" from the fuse and connected directly to the fuel tank.



I then install the wing fairings and drill all the holes between the fairings and the fule tank edge. I all mark a cut line along the fuselage as a gap is required to install a rubber seal.



I then install one of the flaps to begin opening the pushrod hole. It will have to be large enough to let the end bearing go through.

Today was wing mating's day to end with the dreaded rear spar drilling.
First we have to get the plane in the garden and level it in all dimension. My neighbour Raymond is my helper.



We use shims and play with the tires pressure to get the fuselage straight.



Then we get the first wing. The spar and the bolts get greased.



Then the forward spar is inserted in it's slot. Some learning was needed to get the right way to do this. What worked for us was the following, insert the spar as far as possible, then wiggle the wing tip to align the holes and insert an upper bolt. Wiggle some more to insert a lower bolt. For the rear spar, it just gets inserted in the fork, fine tuning will be done later.
On the picture I use a small mirror to verify if the holes are aligned before inserting a bolt.



The is one of the fuel tank brackets, a small bend is needed to get it snug with the bracket on the tank.



Here a view of the four installed bolts, two big and two small bolts. The lower bolts are not completely inserted as the landing gear welding is interfering in front of the longeron. My bolts are a bit to long, I'll shorten them for the other wing.



This picture shows the rear spar, it's not completely snug because one part of the fork is hitting the innermost wing rib. This will be taken into account for the final fitting.



After the second wind is installed, begins the long process of tweaking everything. First the wings have to be perpendicular to the fuselage. For this we took three measurments : from the wing tip to a central point in the rear fuselage, the alignement of four plumb bobs hanging from the leading edge, and the alignement of a rivet line on the wings and the fuse. The two latter showed that the wings were slightly swept forward ay about 3/16" at the tip.



We file away 1/32 of the rear spar and of the forward part of the fork (the rear part does not interfere with the wing). The sweep is now zero, so we go on to incidence measuring.
Incidence is adjusted by moving the rear spar up and down in the fork. We first check that the fuselage is still straight, then using the block shown in the plans, we check that the level is horizontal. The measurment is done at a few points along the wing span. Both wings are now at the same incidence and the edge distances for the rear spar drilling look good.



Then the drilling block is clamped in place (with some difficulties, it's quite cramped) and a small hole drilled.



This is the exit hole of the right wing , it looks good leaving enough edge distance.



This is the exit hole on the left side. The center of the hole is in the square, but as I file a bit of the fork on the right there might not be enough edge distance if I leave the hole as is. The day having been quite long, we decide to take new measurements tomorrow.
If the edge distance proves to small, the solution will be to drag the hole slightly to the left during the drilling to final size which is two and a half time the present size.



We have a plane. Almost!!



And some happy builders. but let's not forget the photographer, Sabine who gave a hand whenever possible.

Wing mating is expected in the next days. But before a few tasks have to be done :
- find the drawings for the wing, the flaps and the ailerons
- take the flaps and ailerons out of storage, prepare associated hardware
- fabricate a drilling guide for the rear spar
- fabricate the spacer as shown in the plans to measure the wing incidence
- prepare the bolts for both spars
- mark the rear spar fork for the allowed spot for drilling, the center of the hole will have to be in the little square



- install the fuel tank brackets



-install the rod ends for the flaps. To insert the bolt I had to remove the whole assembly as the gap between the skin on the left and the part was too small.



- begin drilling the holes in the fuselage for the flap rod, the hole will be enlarged once the flaps are installed



- take the wings out of storage
- mark the holes that will receive screws, the holes will be hidden behind the fuselage skin which has to be drilled accordingly




- protect the engine
After all this, the weather didn't look that good so the wing mating was postponed.

Sanding and small filling mainly on the cowls.
But in fact I was more than three hours in the workshop cleaning and moving all the bits so that I can get the plane out. The forecast shows a few sunny days ahead, so I will try to install the wings, at least try fit them and work as much as possible on all that has to be done with the wings on.
