I just bought this, but I have put it through a good test. I am a home woodworker. This summer, I have been working on a pair of rocking chairs with bent lamination rockers and back rest rails. I have been using a friends drum sander for years, not a grizzly product. The gears on the drive motor stripped after 15 years. A new drive motor has been hard to get, expensive and of course on back order. The rockers for my chairs were finished, but not the back rails. I wanted to finish the chairs before my vacation ended, so I began to look to buy my own.
Grizzly had the best price for the size I am looking for. The customer support office was excellent, friendly, knowledgeable and fast. I got it in just a few days. Set up was easy it took about a hour and half to set it up and make the adjustments as directed in the manual. I jumped right in. I ran 16 pieces of white oak 3.5" wide by 24" long. I needed to sand each piece down to less than a 1/4" for a bent lamination. This is what I learned. This drum sander produces evenly sanded lumber. After sanding, the lumber is even in thickness across its width and length. This is a heavy piece of machinery, mostly made from cast iron. Runs very quite almost no vibrations. The drum motor is very powerful and the drive motor easily pulled the wood through the sander. As a test I put a piece of white oak over 8 inches wide and it surfaced one side perfectly. It did a great job.
Putting on the sand paper is very typical of these types of machines. I like 100 grit. Any coarser and it would take a lot more finish sanding. As for installing the sand paper, follow the direction and it goes right in.
The dust collection port is large and moves a lot of air with saw dust. Just a little dust escaped.
My only negative is the stand is a little short. If it was taller it would be a little more comfortable to use. The shorter height did make feeding wood in and picking up the wood from the out feed easy.
Another bonus is that I am going to make a out-feed table from the plywood crate the sander came in.
High quality great machine. Its a great size, it doesn't take up too much room in my smaller sized shop. Yes you can spend more, but then you would have any money to buy any lumber. Yes my friend whose drum sander gave up the ghost is coming over tomorrow to try out my grizzly drum sander.
