I also have the shop fox 8"...
I have not had much time to use it... My technique sucks so i'm sure it's me that can't get a flat edge without ripples on the wide side of a board (non-edge)
However, on the belt slap, i am curious because i get a really loud bang (can't remmeber if it's startup or shutdown), but it's annoying. Sounds more like a metal clang than a belt noise though - are we talking the same thing...
One gripe i have... The on off switch is such that you can't really use the jointer for side roller support for the table saw (ref Tolpin's book - i had it in same location even before i read it and frequently had to move it out of the way for cross cuts or wide ripping). I've toyed with the idea of trying to flip it around or something..
BTW - Are link belts ok in the heavy duty apps? I put one on my GI saw, but am wondering if i shoudl put them on the jointer, bandsaw and pm66... I think the pulleys on the jointer and my steelcty bandsaw are very "V'd" / grooved not sure they'd fit right?
