Building the practice toolbox. Video

[atalla]

Hey all.
Iv through a video together of some work to the practice tool box. I am making lots of mistakes such as contacting the hinges while setting rivits, under dimpling, burrs in holes after dimpling just to name a few. I'd love feedback from all you and your going to find more I'm sure. I will continue with the build and move onto the control surface once I work out some bugs.

Andrew. Cool video. Noobies may want to see that.
Flip the dies on your DRDT. Male on bottom. That helps keep debris from contaminating the female die.
Vans has noobies dimple the hinge but that's rarely done on the plane because it warps the hinge. Plane hinges are countersinked. No big deal on the tool box. Maybe I don't remember but I thought the hinge was higher.
In general, you adjust dimple dies so they touch but I use a c-frame.
Should be a nice tool box. Mine was ugly. Gave it away.

Looks like a nice video. I am wondering if you can build the box with just a rivet squeezer. I've wanted to try it but I don't have a compressor or any air tools. What do you think?

And as a non-builder, I like the suggestion of flipping the dimple dies. It should remove that awkward need to kind of drop the piece as the male die comes down to meet the female.

I'm so glad you mentioned the hinges. Mine did warp along the spine and on its flat. I was able to correct the flat face by hand but I didn't notice the spine warp until I put the pin in. The door flexes when you open and close it. Not too happy with it but rather this than an aileron. I used a pheumatic squeezer not a drdt but yes I will flip the dies.

What is the procedure for cleaning out a hole that has been drilled to size but gets bunged up during dimpling? Should I just run the #40 through it again? In this case the part was partially riveted to I was worried about the lack of deburing.

I only have a 3" yoke if I had a 4" everything except the Handel would be doable I think.

Two things I noticed. First, the dies are not 'tight' enough. You really can't over squeeze dimple dies with a single piston squeezer. Tighten until they touch, let off the pressure (unplug the air) then tighten another half turn. There should be no distortion of the 'skin' around the dimple, only the dimple itself. Second the ram to the squeezer jumps up far to quickly. I don't know if that is how you are pressing the lever, or if the ram is tight in the yoke?? It should move up to the rivet very slowly if you press slow, which makes the whole process more controllable.

Thanks for your input mike. I am using a foot pedal and this is eliminates the feathering action of the squeezer. I agree with you and do think I'm under dimpling. I set the dies by bringing them into contact with the work Peice tightly and than adding a half turn to the set holder. I will try your method for the remainder of the build.

Cheers. Andrew.

If a rivet won't go through, run a bit through by hand.

I prefer the male dimple die on top, at least with the DRDT-2, and with a mounted pneumatic squeezer. It prevents the scratches on the outer surface you get when you "search" for the hole. I've never had a problem with debris in the female die.

Part 2 is out with some more questions as well as i walk through some more errors
