Title: Changing flywheels.
Post by: Tony Bird on July 31, 2019, 11:01:27 am

Hi,

Let us see if I can make a better job of getting the the photographs in order than I did in my last post.

While having a bit of a clear out I found a large flywheel, well isn't a flywheel exactly it was possibly a pulley that had a belt from some form of machine.  I probably bought it at a club bring and buy sale some time ago as a come in useful item. It is 8" in diameter and 1.1/2" wide.
Some time ago I built a Beam engine from charity shop bits and pieces and used a pair of wheels from a brass canon as flywheels, these flywheels were a little small so the engine runs quicker than it should.  Alas this flywheel is too big to replace them.  However it could be fitted to a vertical engine that I made and the flywheels from this could be fitted to the Beam engine.

With 'New' flywheel.

With Vertical engine flywheels.

So the idea is to clean up the 'New' flywheel' and fit it to the Vertical engine and if I like the result if its flywheels to the beam engine.  So today I made a start on the flywheel; it was cleaned of paint, the large securing hole was  plugged and it was fitted to a face plate to make the centre bosses smaller and concentric.

The machining finished it was painted with primer.

I now have to bush the centre so that it will fit a smaller axle.

Tony.

Getting better the photographs in order but need to get text to line up with them though!
