I have what I must believe is one of the post 1980 examples. I'm curious regarding your statement that the post 1980 production pieces have a cast iron frame. How did you determine this? I'm no metallurgist and I'm not going to subject mine to exhaustive or destructive testing but the frame certainly does not appear to be a cast or grey iron part. I've machined fine grain cast iron and the surface never quite looks like steel. So either the material used is tyhe finest grade iron castings I've seen in some time or they're actually a form of steel... Jerry |
