Thank you both  :) Somewhere near balanced will be fine for me. I will finish up the rough edges and put a radius in the corner by the balance weights with a selection of files.
Best regards

Great work, that looks nice! :ThumbsUp:

It would be fun to see an model engine with one or two primary balancing to compensate the forces of the accelerating piston. But indeed no need for light weight piston and connecting rods!
It is possible to test the balancing, mount the crank in  the lathe with fitting the connecting rod and bearings. And connected the rods with an elastic at a fixed place, for example a wall. And supports it with a counter center.

Thank you Alex  :ThumbsUp:

I added some more elbows to the cooling system and neatened up the pipework. The feed to the block now goes over the flywheel end to make space for an injection pump. The connections also are ready for when/if this gets installed in a tractor and the radiator moves to the front.
Best regards

Whilst thinking about the next steps with the diesel I continued with the 360 camshaft for this engine.

First step was to make a thrust washer for the fixture as I had found that the shaft would slide along on the deeper cuts unless the clamp bolt was very tight. The rest was much as before, spread over several evenings to reduce the chance of me losing concentration and having to start again.

The new cooling system is better but on the limit at full load.

Best regards
