Norton V8

For anybody unaware of this fascinating rebuild of  a Norton V8 motorcycle by Allen Millyard - the series of videos is worth watching. The latest of these deals with the installation of new cylinder liners, and the sealing of the cylinder heads, which is accomplished through the use of bronze rings in a recess around the liners.

I have been fascinated by what Allen Millyard does. And he explains it in way I am saying to myself: yes, this sounds logic, I should do it the same way. But there are worlds in between what he is able to do and what I am capable of. 
Well, I can switch the spark-plugs. Isn´t that something ?
