Alright chris, stop and slow down, sometimes I look at my posts and think how can anyone decipher what I'm trying to say......my concern is will aluminum feeders at near top of its load capacity expand and contract too much to be safe? I've only heard that some people don't use it as a rule.....or is there enough cushion in the tables to allow for that of course proper torque and no=alox being used. or is the load too high for aluminum?
