    The sand idea works great I use sand box sand from the local HIC
    you want the finest (smallest) grains you can get filler up don't pack it then bend a way you need to leave some room for the sand to move while bending

    I've had good results in bending EMT up to 2.5 inches OD by packing sand inside and capping the ends, then heating with an O/A torch and tweaking. In fact the bending went so well, I had to reheat and straighten a bit.

    You didn't tell us what size and wall-thickness of conduit you want to bend.
