Hi,
This thread is about creating a model stationary engine from bits and pieces that have been bought or were already in stock.
At a model show a brass casting of a beam engine cylinder was bought from a traders scrap bin it was a bit banana shaped but didn't cost much more than its scrap value. The same bin provided some much over size bronze cylinder covers again at reasonable cost.
A long time after this purchase the cylinder was machined to see what could be made of it.
First Machining.
The cylinder was then bored. After boring it was decided that the cylinder could be used as the basis of an oscillating engine.
Machining portface.
Milling portface edge.
Cylinder nearly finished having a 1" bore and up to a 45 mm stroke.
A 9" diameter cast iron flywheel of unknown origin that had hung on the workshop wall for many years came into play.
The flywheel cleaned up and the cylinder with its covers made and fitted..
In another thread I described cutting a slot in a piece of steel by chain drilling, it was to be used as a base for the engine.
Some brass legs were machined.
A friend had a beam engine that he had bought but always thought the flywheel looked a little on the light side so we did a swap and I ended up with a bronze flywheel. This is how the part made engine looked until a few days ago.
When cleaning out the workshop an event that doesnt occur often enough; I came across some 'T' section brass that could be used to make some axle pedestals. So two short lengths were cut and machined.
This is how things looked at close of play yesterday.
Bearings and bolt the pedestals to the base next.
Regards Tony.
