The significant engineering task of installing a new cylinder liner is one not to be taken lightly. I entrusted this to Blane Precision Engineering of Killearn not far from me and near where Bob Macintyre planned to have a garage with Alastair King...

 

....note however that not only have the conrod clearance indents been re-machined but that the tiny...perhaps 1.5 mm hole into the cylinder has been re-machined through the new liner fitted...

 

 

...machining off the old spigot and retaining the same height is a job not many would say they could do well.

 

 

All of this incredible expertise is due to one man. Mike Cowie who runs the show.

He is ex Rolls Royce in Hillington - 25 years -and knows everything about Merlin and Griffon engines.

 

I think for certain there must be only a handful of people like Mike in the UK today.
