I find this fascinating, and your work looks very precise and professional!

I bet Landon is learning a ton from you, watching and helping.

~1.5hrs
Landon started drilling out the holes to final size. I had it all drilled out with a #40 and alternating holes with silver clecos. He drilled up to a #30 and put in the copper clecos then removed the silver and drilled them out as well. He did most of one side, I'll probably finish up tonight.
While he was doing that I finished shaping the control horn and fitted it.

Tom
thanks for all the comments guys, it means a lot!

I was doing a little bit of introspection lately, don't think I came up with anything profound though....
I do think I am a different person now than I was when I joined this site and started undertaking projects, the canoe, the FS17, now the plane, as well as all the other little side projects that I would have never even considered in the past and now contemplating a huge boat project in the future. In my younger years I was a reading addict, every spare minute was spent reading novels. Not a bad hobby really, but certainly not productive. Then I spent a 5-8year period just as dedicated to online gaming, which again is not a bad hobby, and in remote areas is a great way to be 'social', but still not productive. Building these boats has changed my daily and family life, and I think has allowed me to raise my son better.

A large part of what allowed me to make those changes was the encouragement from all of you guys here. I knew nothing starting out, had never worked with wood before, very minimal experience with fiberglass at work, etc... but you guys gave me the confidence needed to get started and to keep going one day at a time producing things I can be proud of. I probably don't say 'thank you' enough, but it is something I always appreciate. I should probably work more at encouraging others here as well.

Anyways my bit of introspection for the week/month/year?
Thanks!

My kid won't spend 5 minutes. If my wife didn't depend on it, we'd have the internet off for a week.

I have no idea what clecos are, but can google it.

They are the temporary spring clamps in all the holes, we use them for alignment and holding the parts together before and during assembly.

It's what makes it look like hellraiser from the 80s.

Used a lot in autobody for welding. Keeps the panels aligned. Holes left are perfect for spot welds.

Or in our case, rivets.

~8hrs
Did the final trim along spar rivet line of the leading edge skin.

Drilled out the hinge holes on the brackets. Debuted all edges and holes.

Hauled everything over to the hanger I work at and prepped for priming and primed.

Put the extra mixed primer in the freezer to keep it from kicking.

Went back the next day and wrapped everything in towels and brought home.

We riveted the skeleton together and then the skins and control horn. We brushed primer on both sides of every joint and seam before assembly and riveted together "wet."

A few weeks ago I had Landon working on a practice sheetmetal project with solid driven rivets. His comment yesterday was "this is a LOT easier." ...... I agree with him, pulled rivets feels like a cheat code for assembly. No stress and much quicker.

Once done brought the finished rudder inside over night for the primer in the seams to cure. Was fun waking up this morning to a nicely finished part to greet me.
