1. The idler drum, when unloaded and spun by hand, rotates with out any catches or glitches but it certainly seems a bit stiff. When you spin it, the spin dies out pretty quick (less than a 1/4 revolution). Whereas the drive drum, when spun, spins easily and keeps spinning for several revolutions. So my question: is it normal for the idler drum to rotate 'stiffly'?
2. The sliding part of the idler drum (i.e. sliding in the two side frames) is a bit sticky. I tried to clean out all the old sawdust etc but maybe I should pull the side frames apart and do a more thorough job. Any comments on this?
The belt sander seems to work ok so maybe this all is normal. Thanks for your time and expertise.
