Does any know of a production 4 or 6 inch riser to fit a g0796. It best clones the South Bend mill but still don't find risers for them either. Grizzly's tech support offered no options and said they had no examples in which to give me numbers, zero help. How much of a clone is this clone? Will the j head riser fit? One ebay buyer said his BP riser on a true BP still had to be fitted to even be set down. I don't think going by the outside circumference will be enough not knowing the interior casting. I really don't want to open her up just yet but I may have to.
