Did we make the right purchase decision?
Our woodworking club recently purchased this machine and placed it into service. It replaced a drum sander of another brand. Soon after, we found the front drum was not parallel to the feed table. We had to place shims under the left side of the feed table mounts that were almost 1 mm thick to get it parallel to the front drum.
The instructions on Pages 12 and 13 in the Operating Instructions for setting rear drum height and parallelism are confusing. In general, it is a very poor manual. Most manuals for drum sanders include information about dimensions of sanding strips. This one does not. The manual is titled Operating Instructions and Parts Manual. There is no "Parts Manual".
We purchased the Delta brand set of three sanding strips that are advertised to fit this machine. They are too short. The Delta's specs for this machine say the strips are 92 1/2" long, and that is the length of the strips that come in the set. However, when you try to install one of these strips, they are obviously too short. The strips that came installed on the machine are 93 1/2". That one inch makes a big difference.
Even though we have a robust dust collection system, lots of dust escapes and is dumped on the floor below the outfeed side of the feed table.
Maybe after we learn some things about this machine that the Operating Instruction should have made clear, and we receive the bulk abrasive belt material we have on order and can cut strips to the correct length, we will learn to love this machine. We will see.

Great sander for any shop
Great for large glue-ups and small ones. Just love the finish and time savings. Works great on quartersawn Oak, NO tearout and NO snipe. Fantastic feed rate adjustment, and heavy duty belt. Sized just right, not too big or too small. In my little shop, it's hard to justify having a dedicated sander and giving up the floor space but it's well worth it when I consider the time savings and consistent finish. It would be nice if it were more mobile
