machines which I have made, am making, or intend to make, and some other stuff. If you find this site interesting, please leave a comment. I read every comment and respond to most. n.b. There is a list of my first 800 posts in my post of 17 June 2021, titled "800 Posts"
I bought a 130mm diameter lump of aluminium rod, 460mm long, weighing 16kg, off ebay. It was described as excellent machining material, so I put it to the test. I need a driving wheel for the beam engine.
The driving wheel fits between the flywheel and the governor column.
The aluminium disk straight off the band saw. A perfect cut from a well adjusted saw. Took about 5 minutes to make the cut, using plenty of cutting fluid and slow descent of the blade in order to avoid jamming.
It turned beautifully. Using a HSS tangential tool. You can see a mirror reflection even as the turning as happening.
