The Armset is the replacement handle set used on the Doubell Jumbo MK2, MK3 or Hyperstat brick-making machinery. It is comprised of an inner arm handle (for the carrier plate / stamper lifting), the outer arm handle (for the mould bracket / mould box lifting) both rotating around a 32mm handle shaft that is further facilitated by two heavy duty mounted bearings.
 
Parts of the arm set can be repaired with welds if damaged; but it is generally a slow wear item and once wear is seen at any point, it is advised to replace the set as a whole. Typically, this part is replaced primarily when machinery is left out uncovered to rust in the elements.
