[SEL] Follow-up to Hornsby-Akroyd Piston Question

[Arnie Fero]

Hi Folks,

I received this reply from Ray Hooley regarding my question of a week or
so ago.  So if one has a piston with the removable lands feature, it's an
early one and thus probably quite rare.

See ya,  Arnie

Hello Arnie.  Yes, I am familiar with the use of removable piston lands.
Hornsbys used them for a period in the early development of the Hornsby-Akroyd
engines.  It was a convenient way of varying the compression until they had
found the optimum - then they would produce a one-piece piston. I have drawings
of the various designs that they experimented with.  Regards, Ray Hooley.
