    Take a look here:


    Make your bushings out of whatever you like...

    Yes that works too, but on bigger wheels that mean s a lot of balancing and dressing to get it running true as bigger wheels have "T" or "top" painted on the wheel to idicate in what position it should rest on the spindle or bushing to be as concentric as it was when it was turned to dimensions in the factory. For 7" wheels or so I wouldn't expect much issues, but those 400 mm / 16" wheels really like being balanced at least someway before anything.

    Takes 1" bore wheels that don't appear as popular as the 1.25" bore.

    Before I hurt myself, any reason I couldn't use 1.25" wheels with a bushing?

    I'd assume the bushing shouldn't be press fit (expansion from heat, etc) -- any recommendations
    on clearance?

    Takes up to 8" wheels, will probably put 7's on.

    Thanks.

    Tony,
    They are called grinding wheel bushings!

    0.1 mm clearance ought to do it, that is what I got on a big Johansson grinder and a small Jones & Shipman. You can make the bushing out of steel, but do not use aluminum or brass as they expand more than steel.

    Seems like there was an article in the magazines that used Babbitt or lead poured into the wheel then bored out and balanced.
