Re: Comparing Machines
Don't be afraid of plastics. They are a good thing in the world of mechanics. They operate quieter,do not require lubrication, and have a lower cost to mfg. as opposed to metal . The plastic reciprocator (drives needle up and down) will break when you hit a hoop, sparing metal drive shafts,gears,and other drive components from becoming damaged.
