Default New builder critique

Hey everyone, Iím a new builder just looking to have someone critique my work. Right now I am getting the shop ready for a RV-7 Empennage build this winter. Iíve started the practice tool box kit to get a feel for my tools and riveting for the first time. I just have a few questions.

Am I using the rivet gauge correctly?
How are my dimples?
Do the Flush head of my rivets look ok?

From the photos, I'm not seeing anything wrong.

Now drill out all those rivets and do it again! (only halfway kidding!)

Seriously, go ahead and order the kit. If you enjoyed the practice kit, building the real thing is even better.

Thanks! I did forget to mention I drilled out 8 rivets and reset them. Those 8 wonít be the last Iím sure!

I wish I had taken better care in avoiding scratches though. I know this is just the toolbox, but Iím trying to actually treat this project like the plane.

You will have all matter of scratches, burnishes, and all kinds of marks on your plane, best to come to terms with that now. If you even glance at the aluminum wrong it will scratch, it's very soft. "Let the painter fix it" will be something you say to yourself frequently

Default Lesson learned from tool box

Yes, the tool box project removed any doubt I had about if I wanted to paint or polish.

Your work looks very well done.

The one thing I noticed that needs attention is the sheet metal edges.
It looks like they still have the sharp edges and tooling marks from the manufacturing process.

Read about how to smooth these edges to remove all signs of these imperfection. When you run a finger over the edges, there should be no possibility of getting a cut.

You'll find that when you take the blue vinyl film off and expose the fresh aluminum cladding it will be so soft that just about anything at all will mark it up. You can write on it with a sharpie, then take a rag with acetone and remove the writing, and you can still read what you wrote in the surface scratches from the sharpie felt-tip. There is no avoiding it while working on it.

The first thing the painter will do is scuff it all up with scotchbrite or sandpaper anyway.

This is a very good point, seeing a close up of the edge shows I didnít smooth/ debur the edge as well as I thought. I am ordering a Deburr wheel as we speak. At the time of assembly all I was using was some sandpaper. Thanks for pointing that out.

A quick hit with a smooth single cut file 90 deg. to the edge will take off the tooling marks (punch tabs,shear marks, etc... ) You can then finish off with an edging tool, like a V-deburrer, or hit the edge with a file at 45 deg. on both sides.
Not only does this save time and wheel wear, it will square the edge better than just the polishing wheel alone.
It doesn't take a lot to clean up these edges.
