Wire seems to enjoy hurting people.
But I love the stuff.
My time learning how to make screw in eyelets for my hand made fishing lures was well spent. Every new skill I pick up seems to inform my next project. Working with wire is a really worthwhile thing to learn.

One thing I don't really understand is the relationship between the size of the cams on the crankshaft and the performance of my little tin can Stirling engines. With this lack in mind, I thought I'd build a completely adjustable crank shaft.
With it, it should be easy to try a stack of different configurations to see what they do.
The cams (bits that are offset from the main shaft) should offer different combinations of engine torque, and speed when they are adjusted to different heights.
Ideally I need an adjustable chamber for the displacer as well. I'll have to feed that idea through the invention engine at some stage because I have no idea on that one.
Once the screws are undone as far as they can go, all the brass bits fall out with tap and a jiggle.
Lots of taps and jiggles actually, but they all come out in the end.
In my adjustable cam, the brass tubes that accommodate the cams have had an extra hole drilled through. Brass is very easy to drill, and a pleasure to work with. I don't think I've ever done anything with brass before.
I officially like brass.

Also, many other people have used these as the adjustable bits on Stirling engines, and my only contribution to the science is to take their use to absurd levels.

All the brass bits are taken from a strip of electrical connectors.
