I picked one of the old Ryobi WDS 1600 drum sanders recently. Ryobi stopped making them quite awhile ago, but the design is very similar to the Performax or Jet. It was easy to see it hadn't had much use, and after talking to the previous owner I found out why. He said when he first bought it, he had someone come by and help him set it up and install the sandpaper on it. After the sandpaper wore out, he tried to replace the sandpaper, but he couldn't figure out how to do it. He ended up trying to glue sandpaper to the roller, but that didn't work either . So the drum sander just set where it was at in his basement. He was in the process of moving to another house, so he put the sander up for sale . I got to looking at the sander and I could see why he had difficulty. There is a clip on the inboard side of the drum that is really hard to get to, especially if you are trying to retract the clip, hold the drum in place, and tuck the end of the sandpaper strip into the clip at the same time. You need at least three hands - bad design. I made up a third-hand gizmo that mounts using the existing hardware. It's nothing fancy, just a spring loaded bolt that extends out to catch the drum's sandpaper latching clip and holds it in place while I tuck the end of the sandpaper into the clip. Once the sandpaper is in place, a slight roll of the drum releases the bolt and it automatically retracts itself out of the way. Works good . This is the sander as is, in it's poorly engineered glory - Here is a pic of the spring gizmo - Here is a pic of the gizmo installed on the sander - And here is a pic of the gizmo doing it's job, holding the clip in the retracted position - And released once again - I'm ready to install some sandpaper and put this drum sander to work now . .
