Embarking on a new project.
Bought a set of plans for a model of a 1910 Holt tractor engine, they were the predecessor to Caterpillar.
Its hopefully going to be a 4 cylinder overhead valve engine.
A lot of small parts for my big fingers and machines. lol
1 inch bore and 1 5/8th stroke. It has wet sleeves and individual jugs on a two piece block.
Posted the camshaft gear the other day, started on the front gear case today.
Some scrap aluminum from an aircraft plant, this stuff sure machines nice.
