I had one for several years and the tip finally failed. I bought a new Ryobi cordless belt sander and it works much better until I have to change the battery. Changed. Then works great. I would never buy the corded Black and Decker again.
Please contact your local Home Depot or BLACK+DECKER at 1-800-544-6986 for further assistance.
You could but you will use a lot of belts and create a lot of dust
... not really....
Probably, but you won't need one. Just empty the one you have and keep going. Better, just ignore the bag... it doesn't work well anyway.
You will need a bigger floor sander
To shave 1/4 sounds to me like using the wrong tool for the job. You need a saw, then sand it to precision.
