Humidity and new parts

[Roger Jolly]

Hi Karin,
              The Renner bushings are coated in graphite which is
hygroscopic, thus attracts moisture.  The Abel bushings are clean, and do
not experience the same problem.

The machining tolerances seem very similar, but they are 1gm lighter.

You will travel far less wippens than using the ''Genuine Parts''.  The
Hornbeam machines better, and IMHO is far more stable. 

Regards Roger
