I may be wrong, but I would be very concerned about the belt tracking on that machine. In my experience similar style machines, of that design have serious belt tracking issues when grinding....the span between the idler and contact wheel is the problem....it will track fine with no load on it, but if you apply pressure to a work piece, the belt will "jump" in the direction you apply the most pressure. In some cases I have even seen the belt come completely off the machine. Now let me be clear...I have not used this specific machine, but have used a good number of like designs...and they all suffer from what I described. I actually have something similar in my Forging shop, but its issues are so intense that its been relegated to deburring and other minor grinding chores.
