Noting that you only need a 120 grit finish, I have a few thoughts. First, are you using open-coat paper for the 80 grit – it will not clog as fast as a closed-coat paper? Also, stearate-coated or non-coated? And, of coarse, hopefully not garnet.

Second, for dimension lumber (construction grade 2×6’s) I would probably start with 100 grit so I wouldn’t spend as much time sanding out the rougher surface an 80 grit paper leaves behind.

Have you considered a hand-held belt sander for the coarser paper and then switching to a ROS for the finish (120 grit) sanding.

Finally, if only sanding to 120 grit, I ponder if a planer might be a less expensive alternative than a belt sander. Or even, quite frankly, if there would be a need for you to do sanding on planed boards unless the sanding would be needed to create the rustic look.

But, of coarse, there is a great pride of ownership for having a drum sander in one’s shop and they do their job very, very well.
