Rated 4 out of 5 by from Beefy tool, Performs well, Setup was OK I just received my 31a and have only been using it for a few weeks now. So far, no real issues and it has plenty of power for what I need it to do in my shop. Assembly was straightforward and setup went fairly well. The sander was well packaged for shipment. What attracted me to it is the 1.5 HP motor, the 12" disc, and the hinged belt roller cover plate that allows for easy contour sanding. Like most combination belt/disc sanders, its ability to route dust to a collection system is marginal at best and is probably only about 50% efficient (max) even when connected to a 1,100 CFM dust collection system using only 10' of hose between the dust collection system and the tool. It does not help that the bolt-on 4" port located at the base of the stand includes no way of sealing it to the integrated duct work; it needs a gasket. I fabricated a seal from foam weatherstripping before I attached it to the stand. When sanding with the belt, dust collection is most efficient when the table is vertically positioned. The dust-collection port under the sanding disc does a fairly good job in gathering dust but extraction air flow is limited due to the tight spacing between the table and the disc, no doubt for safety and accuracy. The cast iron disc sanding table needs to be completely removed to change the 12" disc. Even with it removed, disc access is hindered by a lower guard that cannot be completely removed. The disc table is beefy, in fact, all components are beefy and appear to be overbuilt. While good for stability, it is tough to handle the disc table when removing it to renew the sanding disc. There is a second table/fence assembly that can be mounted over the 6" belt and is also very robust. Both tables have T-track miter gauge slots. There is a positioning stop that helps relocate the tilting disc table at 90° but the bolt can gouge the table surface if you are not careful. The end of the bolt needs to be rounded or profiled so that it will not damage the tabletop. Sanding speed is not adjustable but is OK for sanding wood with either the belt or when using the disc. The sanding belt arm can be easily re-positioned. There is a spring-loaded belt arm locking handle that secures the belt table in any position from 0° (vertical) to 90° (horizontal) with positive stops at 0°, 45°, and 90°. The locking handle is spring-loaded and re-positionable which is a good thing. It is about 80mm long and cannot be rotated 360° without coming in contact with either the belt table or the sanding disc housing. This is even worse when the sanding arm is vertical. The operator cannot swing the licking handle more than about 30° in either direction before it hits the tool. This can be better designed. The bat-handled locking bolt should be replaced with a locking knob to eliminate this interference. Belt tracking adjustments are easy to make but touchy, not unlike many belt sanders in this class. Belt changes are easily performed and the belt tensioning system is well thought out. The machine lacks leveling legs or feet of any kind. Wheels are not provided and must be added if you plan to move the sander in your shop as it weighs close to 300 lbs. Based on how the tool is positioned in your shop and what type of sanding you primarily do, the power switch may or may not be in the most optimal position for you. Since I usually face the disc, the On-Off switch is low and to my left. This is not optimal for me and the switch cannot be re-positioned. There is a 6' three wire power cord on the 120/240v unit and is wired for 120v use. It comes with one 12" disc and one 6x48 belt, both of which are 60-grit. It includes a small miter gauge with no preset stops. The Miter gauge bar includes a T-Slot washer. This sander looks like it was designed in the 60s. You can take that as being either a good or a bad thing. All in all a good investment It get the job done and looks like it will hold up.
