I’m new to the forum trying to figure this posting thing out. I bought a Wilson Rockwell Tester locally(NE Ohio) off of Craigslist and it is missing the weights and test blocks. As far as I can tell the model is 4TT. I am currently hoping to get a copy of the manual from Buehler (waiting on a return email). I saw a thread from a while ago that says the ratio should be 25:1 meaning the weights and holder should be 6kg. I am trying to see if this is correct. Any info would be greatly appreciated. I can’t figure out how to add a picture of the tester.
