The NW Reunion was last night. Freud And Ray Therat did a good job. Lots of folks from Landracing.com where there including a few that came all the way from Kansas. It is nice to see everyone. This is the only time in the year when the BUB, SCTA, and USFRA folks are in the same place.
The middle section of the new spacer will have the same dimensions as the old one. The outer diameter of the upper and lower sections of the new left spacer will be increased or decreased, as compared to the old, to get equivalent stiffness. The OD is increased from 1.027 and 0.945 inches on the old one to 1.193 and 0.193 inches on the new ones. Now the new spacers will have the same stiffness as the old.
One finds, when looking at stiffness, that greater amounts of the lighter metals are often needed to provide the same rigidity as steel. A steel part in some instances takes up less room and is lighter. This combined with steel's excellent fatigue resistance, make it the true "wonder metal."
