Stuart Turner Castings

[Alan Worland 1Participant @alanworland1]

I am gradually working my way through some of the larger castings and have found them to machine well with not too much to take off – until I came upon the cylinder!

I have been removing something in the order of .030 – .060 off the various faces but the cylinder bore which finishes at 1.500 started off with a cast bore of about 1.150!!

Thats an awfull amount of cast iron to remove – I had it all bolted to the large faceplate which required a consierable amount of balancing so I was keeping the speed low and as a consequence it took ages.

Is this done for a reason?

Hi Terry,

It’s the No4 engine I have, it a ‘4’ cast in the cylinder so I guess it’s the right one.

I initially thought it might be a common casting to be used with other designs?

Just seems a lot of material to remove, I have left it 0.002 under for a final hone.

Alan
