I used this belt sander for about 5 months or so without problem, I would even say it was great while it was running! I only used it for short durations on weekends, I am a hobbyist knife maker. There are little issues but they were easily resolved with a little elbow grease and ingenuity. The last straw was tonight when I was sanding some red oak, I was applying some pressure to hog through the wood, not overly much pressure mind you, and suddenly the motor starts letting out this horrible grinding sound. I immediately turned it off and disassembled the main parts to see if something came loose or maybe broke. Everything looked fine so I put it back together, plugged it back in and turned it on. It ran for about 20 seconds, still making the noise, before it tripped the gfci. I have no idea what happened but figured the motor more than likely crapped out. I went to look into buying a replacement motor off the JET website just in case and see that the motor ALONE costs more than the whole unit! I am filing a complaint with the warranty department but I am not very hopeful they will come through on this one and I most certainly will not be buying a replacement motor at $546. I will rethink my review if they honor the warranty (supposedly 5 years on woodworking gear) but until that time I think I will refrain from getting anymore JET tools and would advise others think deeply about buying this tool in particular.

The Jet 1 x 24 inch belt/ 8 inch disc sander is a well-made machine. Compared to Rikon, available for about 100 dollars less, it is fabulous. I know because I’ve been trying to send back a Rikon belt /disc sander I purchased, mainly because it is defective. See my review of the Rikon for details.The Jet has well machined mating surfaces on the cast iron sections, and the cast iron parts are not rough. Jet took the time to smooth out the surface of the cast parts. Not Rikon. Both discs are aluminum and are 8 inches and both have plastic guards over the disc and the belt sanders; however, the Jet has a tilt back top on the belt guard that allows the top idler-wheel to be used on inside circles. The Jet uses thicker plastic around the guards. And, most important, the Jet dust collector ports are sized for a shop vac (small hose). The Rikon vacuum ports fit nothing American made for dust collection.The Jet went together in 30 minutes, including taking it out of the box. The Rikon took me four hours to assemble and it was a nightmare all the way. The Jet runs much quieter than the Rikon, and it vibrates less. Much less. Plus, the Jet is an Amazon Prime unit. This means it is backed by Amazon itself and that is worth something – well over 200 dollars it seems. The Rikon is not a Prime product; thus, if you encounter problems you must deal with the retailer and Rikon. I had trouble with both. If you need a part, or if the machine arrives damaged, Amazon Prime will respond at once. I know because I’ve used them numerous times. If there are difficulties and it isn’t Amazon Prime, stand by for problems.Unfortunately, both machines use handles to loosen the tables, but the Rikon uses the handles on both tables and Jet only uses a handle adjustment for the belt table. The disc table is held by two allen head bolts, one on each end of the table. I mention this because the handles, even on the Jet, are tough to turn. They have a kind of button on top that you push down as you pull the handle up to avoid catching the threads. Then you push the handle down onto the threads and turn the bolt to loosen or tighten the table. The handle on the Jet is a bit better than the Rikon, but not much. Both have a tendency to break loose quickly and smash your knuckles. I’ve skinned my knuckles on them both. In my opinion, these handles do not work.Is the better fit and finish, the quieter and smoother running, and Amazon Prime, worth an extra 100? You bet it is. Plus, I would have saved myself over 3 ½ hours of struggle in a 100-degree garage (heat wave here in northern Nevada). Will the Jet outlast other machines in the same category? I think it will. If you are struggling with paying the extra money for the Jet, don’t worry. You will get your money’s worth in a dozen different ways.AD2

It was a little hokey to put together (you need three hands) but it performs well and is a good all-around sander. Yeah it's a pain you have to dismantle half of it to replace the rotary sanding disk but that's not that unusual. The power switch is a little wimpy, but that all aside it's a nice, solid unit and I have no complaints on its usability.

Turned it on the first time and it worked. Turned it on a second time and the motor hummed, but no movement. I called Jet customer service number from the manual and actually did talk to a person. A new start capacitor was sent to me promptly. I replace the capacitor, but same result. I again talked to customer service, but they had no recommended fix so I sent it back and ordered another. The replacement is operating fine, but the on/off switch is coming out of the metal box it is mounted in. Without disassembling the switch and box enclosure, the fix is not obvious, but the switch works OK, so I will live with it. Quality control is obviously a problem. From an operating perspective, the product works well and the frame is certainly robust. Rikon is now selling a product that looks nearly identical for $200.00 less that might be worth checking out. I cannot give the product more than two stars, but customer service probably did the best it could with the information I could provide.
