Carefully inspected cowhide is cut into strips, bevelled, dyed, decorated and fitted with buckles to produce leather belts. Precision components are assembled into machines that deposit and laser-fuse metal powder, glass-reinforced resin is compression-moulded into tactile warning panels, and finely machined pistons, cylinders, crankshafts and flywheels are combined in working model Stirling engines.

Compression & Extension Springs, Micro Drill Bits, Skiffs, Painted Glass Backsplashes

Computer-controlled machinery coils and shapes steel wire into compression and extension springs before heat treatment and finishing. Carbide blanks are diamond-ground into extremely small drill bits, lightweight composite layers are vacuum-infused to form fishing skiffs, and low-iron glass is cut, tempered and coated on the reverse to create painted backsplashes.
