Bill of Materials

• Universal Rotor (Factor e Farm)
• Small lathe chuck (Factor e Farm)
• 1.5"x14"x1" hydraulic cylinder (Factor e Farm)
• Coupler - to go from 1-7/8 shaft to 1-1/4" shaft. 2" long on wider side, 1" long on narrower side
• [2] 3/8"x4"x6" angle, 44" long - verticals
• [4] 1/4"x1" angle, 20" long - rails for holding universal rotor to prevent it from twisting
• [2] 3/8"x4"x6" angle, 12" long
• [1] 3/4" threaded rod, 8"; [4] nuts - for top-facing end of cylinder
• [1] 3/4" threaded rod, 6"; [4] nuts - for bottom-facing end of cylinder
• [2] 1/4"x2" angle, 4" long - mounts for top-facing end of cylinder
• [2] 1/4"x2" angle, 2" long - mounts for bottom-facing end of cylinder
• [4] 1/2"x3"x15" bar - for table clamps
• [2] 1/2"x3"x7" bar - for table clamps
• [4] 1"x4" bolts - for table clamps
• [4] 1" nuts - for table clamps

Total: $150 in metal from local fab shop

Plus base:

• [2] 6"x7/8" u-channel, 3 feet long ($56)
• [2] 1/4"x2" angle, 2 foot long ($12)

Total budget: about $200 for structure, excluding chuck and Universal Rotor
