Cylinder block ready machined

Hello Steamboaters,
the Cylinder block is ready machined. Maybe some more honing is needed...
No design problems, no defects in the cast iron - everything is fine - I am happy with the result.
Comparison

Here is the CAD picture of the cylinder as comparison. The CAD calculates the weight of the cylinder block with 17,2 kg = 37.9 pounds.
The original part came out of the sand with 21,5 kg (47.4 pounds) and weigh 17.4 kg (38.4 pounds) after machining.
The additional weight of 0,2 kg (0.5 pounds) may result from the drafts of the mold and the rounded corners not calculated in the CAD.

Half a pound variation on a casting of that size and complexity, I would say is VERY close, and as it's not going to go to the moon, of no consequence at all.
Excellent!

Thank you all!
In the moment I am redesigning my homepage. Mostly layout and programming review...
I also started to describe my engine construction in detail - but only in German now.
Hope, to reopen my steam boat register for new entries soon...
For you here two animated gif's from my engine:

Can't stand it to show you this animation - even with German text...

Rainer, I think you are having as much fun doing your CAD animations as you are building the engine!

He's running free! I hope he doesn't throw a con rod ...

Next step. Detail from an original build in the same periode like my example:
My CAD solution:
Had to change some things at the base and at the cross-tie to avoid interferences with the oil lid.
