The side plates are stamped to shape and the lettering stamped in. The plates are then de-burred using a tumbling process.
Threaded rings are cut to length and then machined to provide ridge for fixing side plates. They are then 100% checked for thread with male thread to remove any burrs.
The Top Ring is cut to length. Then formed to shape using a two step stamping process. Then de-burred as required.
Nuts and Bolts are purchased and inspected for threads and size.
Side Plates and Threaded Ring are located in Welding Jig and tack welded in place.
