Will the Magma shovel handle work on the orignal Star Sizer? Also does anyone know the size and thread of the bolt that holds the handle in? I was tighting mine and sheered the damn thing off. Not only do i have to replace it but have to get what's left out of there without screwing it up. Mine has 5 washers that the bolt goes through. Is this correct? Why not use 1 washer and a smaller bolt? Just wondering.
