Thanks, I'm satisfied that I either need to use rails or shafts that are tapped and can be mounted all along its length to prevent movement and vibration.
Can I take a drilling rod and tap threads into it myself along the bottom to mount down? I can get a 12 foot drill rod from ToolAndDie.com for $75 and cut it to length.
Or cnclinx.com has one already tapped every 9 inched but its not long enough for my needs. Wonder if I cut them and mount them evenly together to make a longer rod if that will work?
