high strength brass what ever that is they were ment to be aluminium bronze they drove swell reducers on a welding
machine not to be steel or they would erect welding current but they were a meter long.it was a chain making machine

was the pipes connected to the tapped hole in the bottom of the cylinder
i wonder if it was a pump for gas  ?  what does the valve face look like
john

have you got a sharp hss end mill that would be better than a 5mm radius carbide

Hi
what's wrong with a fly cutter  not to big in dia  with a small radius honed to a very sharp edge would put very light pressure while cutting  what ever you use it needs a sharp cutting edge

that looks like it will make a nice engine the guide at the side may not have been for the vale rod may be a bearing support for some thing else may be a control lever?
