Guys on my 13" Colchester round head lathe I need to locate a screw nut that's part #8297.I know I'm sure Clausing has a brand new one in stock but I am max out at the bank.So that leaves me an individual or ebay.But I need to know what I am looking for other than the part number, so does anyone knows about the screw nut that they could share so that I can go shopping?Thanks for any guidence---kroll
