October 2013-December 2013
Supervisor: Erich Weiler, Owner
Design cutting capable of shearing 6 or 9 gauge galvanized or stainless steel wire with
minimal operator adjustment.
Use in house supplies and equipment whenever possible
Fabricate larger mechanism for holding cutting tool during operation.
Install assembly in alignment with existing critical components
Modify other components for feeding wire, guiding machine motion, avoiding lines, etc.
Manual knee mill, variable speed spindle, belt driven
MIG Welder with gas
Oxy-acetylene cutting torch
Friction cut saw
Most common shop hand and air tools
Challenges to overcome:
Budget limited to under $300 total material and tooling costs (Set of r8 collets, Kurt vice,
Management requests often added complexity without increasing overall effectiveness
Repairs should be easily performed by operator with little training
Use excess inventory for replacing worn-out components
Tools and equipment oftentimes required alignment and repair
Bridgeport vertical manual mill used to make many critically dimensioned components for cutter
assembly. Required rebuild, alignment, and $100 in tooling costs.
Wire masonry ladder machine. Two 6 or 9 gauge (.148”-.203”) stainless or galvanized steel wire
are straightened, while a 3 is cut perpendicular to the other 2 at 6”. A Pneumatic gripper moves
the piece to be spot welded on each side, repeating for each 10’ section.
Cutter mechanism holds 9 gauge galvanized steel wire against carbide tip of lathe tool.
Wire “Ladder” product made in 10’ sections
