    I am surprised that you needed that. I have no problems with mine wandering.

    I have the same sander with the same shortcomings. I also found that when trying to plumb my shop vac into the dust collection port on the back, that when the vac was turned on, the belt would not turn... there was not enough clearance between the belt and the port to get adequate airflow, and not enough torque in the stock motor to overcome the suction. Ultimately, I just wound up scrapping the back of the unit and the flimsy plastic disc sander portion, swapped out the motor with an old craftsman, and bent up a slightly better 'table' that will ultimately have to be replaced with something like the one you built here.

    Nice build ��

    Thanks for the tips!
    Woodworking (and plain old tinkering is just a hobby for me so I can seldom justify the purchase of "top shelf" equipment.
    HF stuff fits my budget and my learning curve. I have no family to pass on any "heirloom tools" (But I do own two
    Kirby Vacuums...one is used for the "front end" of my dust collection system) so I buy HF and look for mods like these.

    A distinct, unadvertised option of these; actual balancing or impressions of same. Sometimes the molded resin wheels aren't consistently dense, or spring post not proper tight sliding fit.
    Mine is a Craftsman branded import, plank mounted with soft rubber feet. Iffy at first, using good 2x42 belts biggest improvement. I don't care for the disk, available grits at 6" diameter are unsatisfactory. I'm no Tuomas, but right angle grinder works fine.
    Sincerely,

    ...we'll learn more by wandering than searching...

    i added a dust collector as shown in these pix. As the dust is carried downward by the belt it just falls captive to the air being sucked in. There is no tendency to suck the belt onto the platten. It is made from some scrap plastic drain pipe, the lid off a coffee jar and some scraps of wood. It works really well. The black knob on the front is the only bolt holding it on, elsewhere it just rests on a shaped support.
