I got the RT-618 and need wheel adapter(s). The machine looks very much like the Boyar Schultz and probably using same adapters, though the Sopoko adapters dimensions on their web drawings are sightly different than the one I have on my grinder. Does any know if the Boyar Schultz (and Sopoko) will fit the Ingar? Maybe even one of you have some for sale? By the way, there seems to be very little information about the Ingar make, though there is a number of different models around. And the similarity to Boyar Schultz so close that I wonder if it is a clone.
