30min
Epoxied the male plug back together and flanged the last of the holes. Very last one and the plywood on the male plug failed in a new layer (not my epoxy joint)
Not sure if there is more flanging to do that size or not, but if there is I will probably make a new male piece from solid wood instead of plywood.
Called Roger this morning and he is still waiting on Rudder drawings for me, so I'm on hold for a little bit.
Total time spent building: 64 hours
Total Cost: $8276
Airplane + consumables + project specific costs: $5340
Tools, etc.. I will keep for future projects: $2936

It's funny how much odd stuff ends up out in the bush.

Re: Narfi's Zenith CH750 Super Duty
I got the blueprints for the Rudder from Roger this week but in the middle of making a storage bed w/ bookshelves and secret cave for my son so probably cant start till next week.
Ordered the 3/4x3/4 angle I needed, just a few inches needed for the rudder but Roger told me I would need roughly 20ft for the entire project, I bought a 25ft stick cut in half. Also have some 1/8" aluminum coming, will need some for the rudder horn.
total for that order $275 (including $30 delivery)
Ordered Some aluminum prep and some primer = $252
I decided to just go with primer I know, PPG 910-704 Super Koropon, it sprays easy, goes on super thin, and produces a hard chemical resistant shell.
Total time spent building: 64 hours
Total Cost: $8803
Airplane + consumables + project specific costs: $5867
Tools, etc.. I will keep for future projects: $2936

Re: Narfi's Zenith CH750 Super Duty
Finally got most of Landon's bed made, still waiting on some magnets and hinges, and will need to paint it (black then scuffed up and clear coated for the old distressed look) once reassembled in his room. For not knowing anything about carpentry and making it up as I went along I am pretty happy with it, just not with how long it took :p
Was able to start on the rudder yesterday, took about 5 hours to make 7 parts and decide that I needed more dimensions/info to make the rest.
Tapered spars are easy, just make them a few inches too long each direction and then cut out the right size from the middle when done.
I borrowed a neighbor's 12ft brake and it's got some quirks, not sure if it's just old or needs some adjusting, it bends sharper on the ends than the middle and doesn't clamp over center, the clamp arms need to be 'balanced' in the clamped position and it's a pain getting both clamped without one springing open.
I got pretty close on my angles for the spar and doublers and just tweaked it a little with the hand seamer back at the tent when done.
The hinge brackets were easy as was the little spar fairing and angle tab.
Was my first time cutting sheet metal with the ulfa knife and it worked really well, though took quite a few passes for the .040, the thinner sheet cut really easy.
I sent Roger an email listing the rest of the dimensions I need for the ribs and skins and horn. Will give him a call as well.

I am sure Narfi has a good reason for not posting any progress on his build. I check daily for the latest info as I am fascinated with his build.
