Have you contacted Grizzly? I have a RT made in India that is accurate. This is the 6" model but do not remember who I bought it from. Possible Little Machine Shop, I also have another RT that I also bought from Little Machine Shop. This is a small 4" RT that does not use dividing plates.
Possibly Grizzly may make good on your purchase From the condition you describe it sounds like a boat anchor and may not be fixable.
