The people over at the bicycle building websites are extolling the virtues of the Reynolds 953 Stainless Steel tubing. Seems that Reynolds 953 SS tubing is so strong, the tubes walls can be drawn so thin that bikes that are built out of 953 SS tubing are STRONGER than aluminum but as LIGHT (OR LIGHTER) then bikes built using of aluminum tubes. Are any aircraft home builders using Reynolds 953 SS tubing in their project rather than 4130 Normalized? Of course, the connection between the bicycle business and aviation is that builders of both airplanes and aircraft are interested in "strong but light" construction metals and materials. Just ask the Wright Brothers! All of your comments and insights would be most Welcome!! THANKS!
