Cheap socket wrench.
Posted by Don Stauffer on Wednesday, June 20, 2018 7:51 PM

I had to attach the motor mount for my Wasp engine (thread in aircraft forum) with 0-80 cap head machine screws.  In the position they were in, the open end wrench set I have would be a pain- the screw is surrounded by a lot of junk.  A socket would be ideal.  But I didn't have a set of sockets that small.  I remembered I had once made a socket wrench from aluminum tubing one time, so I tried it again.   Looked like a 1/8 inch aluminum tube would just not quite fit over the head- just right.  I had a lot of K&S tubing on the bench, so I tried it.  I took a block of MDF, and drilled a 1/16 hole in it, deeper than the length of the screw, and inserted the screw so the head was supported by the MDF.  I placed a 3" length of the tubing over the head (carefully) and gave it a few taps with my modeling hammer.  It swaged the end of the tube down over the head snuggly.  In fact, the screw came up out of the hole when I lifted the tube.  But the screw was easily removed and it looked like a nice socket wrench.  To make it a bit easier to handle, I cut a length of 1/2 inch dowel, drilled a 1/8 inch hole in one end, and rounded the edges of the dowel a bit for comfort when using it.  Put drop of CA on the end of the tube and stuck it into the dowel. I drill out the holes in the manifold where the mount gos with a drill appropriate for tapping for the 80 screw. Now, I didn't bother to tap the holes in the engine where the mounting screws go.  I figured a #80 screw like that would self-tap easily into the hole- it did.  Drove the screws with no problem.  They were brass- dropped them into brass blackening solution before using them.

By coincidence, got a new Micro Mark catalog today, and found a set of four sockets for small screws- 20 bucks for the set.  I figured I saved almost five bucks, considering the value of a three inch length of K & S tubing.

Anthropologists think that a good measure of the advancement of a species is its ability to devise tools to achieve tasks.

Are you implying Don is the most advanced ape here?
