    Default Castor tray for a large-ish machine?

    I have a borrowed medium size metal bandsaw in my man-cave:

    which is always in the way. It needs to be near the door for cutting large stock, i-beams, etc, but that prevents me easily wheeling out pallets, trolleys, personnel lifts, et c.

    It is apparently 371kg, so I could just bolt 4 heavy duty cast castors under it, but that would make it uncomfortably high, and a bit unstable (though vibration wouldn't be a huge problem?).


    Some kind of trolley that the base sits in?

    A set of castors inside the hollow base, that lever down when relocation needed?

    Do you have a pallet jack?
    If so, a simple frame that will sit underneath it and allow you to move it with the pallet jack is an option. I’ve done that with a couple of my machines.

    If you do put casters under it, make sure you put them on a frame that locates them outside the base as when the wheel moves towards the center the contact point moves inwards reducing stability. Try and make it so the wheel contact point never moves inside the existing base outline.

    Hadn't thought of a pallet jack. I can borrow one. Much more convenient than a forklift


    I have had castors make things unstable, usually when they jam while changing direction, and the machine/trolley/thing needed to be pushed/kicked.

    Some castor designs are much worse than others, but I haven't yet worked out what aspect of the geometry causes it.

    This is a light duty trolley for a parts washer, beef up the dimensions and materials as needed.

    40x40x3 perimeter frame, outriggers on each corner to take the castors, incorporate a jacking bolt into the outriggers if you want it off the castors.

    I organised my trolley so the frame is an inch or so off the floor, keeps working heights much the same.
