The image above shows the revised horn concept, with removable liner plates. These can be changed to give greater clearance for roller bearings or less for plain bearings.
Once we had a final concept, the drawings were completed, and the components ordered. Using computer controlled laser cutting and plate folding, all the parts were produced and fit together accurately with minimal work.
We hope to be able to press the side plates in the final version, as in the original design; tooling for this is expensive so we need to be sure the design is right....the beauty of Computer Aided Design!
