IMO, you don't need any give with this machine,doesn't matter if it is for Lining, Shading or Packing, let your volts and hanspeed do all the work..It is "slightly" dampened, but treat it as a no give machine..I think some people run it with bands over the top of the Abar as that is the way they come packed...I removed that band, and run mines with out it..
