16kg aluminium rod. Cutting off using a band saw.
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.
Did you first hold it with the outside jaws, turn a recess, then turn it round and hold as seen now using the inside jaws?
How thick is the workpiece? How thick is the job?
Hi John, yes that is exactly how it was done. workpiece is 32mm thick. Not yet decided on thickness of finished wheel. Maybe 28mm?
