Big day in the project. Test fitting wings and spars. Earlier in the week I got help from my family to lower the fuselage from the storage space I'd made for it. My son and I lifted the frame up above our heads to put it up there. That hurt the back for a week so we going to use additional help to get it down. I rigged up a pully from the rafters so that my wife could provide some additional lifting power. That made all the difference. I'll have to weigh the fuselage when I think of it but it's darn heavy. Back to the project. With the fuselage down, we set it on a frame with casters on it. This frame was previously the base of a wing rotisserie for another project. It's proven handy again. We tried fitting the loose spar to the frame only to learn that the fuselage needed a bit more prep. The wings are connected to the fuselage and one another through some beautifully machined aluminum connector plates. These plates run the full width of the fuselage and the wing attach bolts pass through them and through the welded steel frame. The bolts run through these plates and through a pair of tapered bushings on either side of the spar. I had 4 of these bushings in my parts and I discovered that both of these plates require bushings for final assembly. I found one more bushing in one of the plates but it appears that I'm missing 3. I don't recall drawings of these bushings so I'll have to get them made using dimensions from the others. To prep things fully, I removed these plates and cleaned them up. This allowed us to slide the wing spars into the frame and then tighten the plates up on either side to fit everything properly. This also allowed me to locate the rear spar properly and drill the hole for the connection bolt. Doing this locks the wing into the correct incidence. I'm going to reference the location of the LH wing to locate the RH wing and set its incidence. This will also allow me to set an even and proper sweep for each wing. Epoxied the root rib on the RH wing in place. The remaining ribs will be positioned using the root rib for reference.
