Fuselage

July 2004. Built the jig and started to build the skeleton of the fuselage. Major leap in interest, wings get a bit repetitive after a while.

Jig and front half of the fuse, minus the seat back bulkhead. Jig made from 18mm plywood laminated to give approx 1.5" thickness and cut into 150mm and 100mm widths. I love these bi-lingual measurements!

The fuselage is built inverted initially as the longerons are straight and level in this orientation, at least up to the area 29.75" from the front.

Rear half, minus a couple of bulkheads, the longerons still require notching to allow the 611 into the jig. The 610 was removed to drill the rudder cable hole before I forgot!
To the initiated this gives away the small wheel will be at the front!. The large blue web is not on the tail dragger as this is where the main undercarriage mounts bolt on.
Large chunk of timber was put through a friends thickness plainer to 1.4" thickness to simulate the main spars.
I give up on haw many times I measured the position on this bulkhead and also the level of this bulkhead and level and plumb of the firewall. This bulkhead AKA 604 is not plumb and sets the incidence of the main wings.
The forward structure going in, there's quit a bit of fabricating in here to get everything running smooth so the skins flow nice.
This is the lower firewall gusset, the drawings for this takes a few looks at to figure out what goes where.
And from the outside you have to notch the front to let it joggle around the weldment. It also requires a couple of gentle bends to lie flat
This is the top gusset, shown on the plans but took me a while to find
And from the inside. Still requires the bend tweaking a little to sit flat in all plains.
Stringers getting placed and checking alignment of all the bulkheads etc.
Rudder pedals placed in forward section to align the centre support and drilling of the bearing blocks.
Side view of the baggage area.
Another view of the rudder pedals. I made these ground adjustable, with some effort!
There are 4 positions available giving an adjustment of 4 inches.
Looking aft these are the seat ribs followed by the baggage floor ribs.
Underside, which will be the top side, of the seat ribs.
Side view with the bulkheads now drilled to the longerons and stringers.
And from the rear. Note red strings for the centre lines and to verify bulkhead heights to get a smooth skin.
