The two wide belt machines that were on this auction were both three belt models. ?Each belt had a separate motor. ?The table belt had a separate motor to move the stock through the machine. ?Like you, I have no practical experience with these machines. ?The control panel for the machine looked like it had controls for each belt. ?Joe Calhoun has a multiple sanding belt machine in his shout in Ouray Colorado. We got to use it during one of the classes I attended. ?His is either a two or three belt machine. ?I don’t recall for certain which. ?Unfortunately, I didn’t think to look and see if it used both belts all the time. ?

It was very useful to rough sand large flat projects, and to some degree to bring those items to a correct thickness. ?I can see a great advantage for production work with one of these machines. ?Unfortunately, they eat a lot of power, and they have rather large dust collection requirements.
