Good Evening All. Last weekend I purchased a K&T 307 S-12 combination mill. I purchased the machine under the claim that it was in operating condition when it was removed from service back in 2013. The 1st problem that I observed is when we loaded it on the trailer. I attempted to lower the knee and when I tried to turn the handcrank it was locked up solid. The gib clamps were loose and there was zero movement. I am not familiar with the machine so am I missing something very basic? This mill was purchased from a gentleman named Nethawk who had posted here on this same machine back in 2006. With the help of this community he was able to bring the machine back into operation. At least that is the conclusion that I come to when I read through his 2 page post. He passed away many years ago and his son sold the mill to me this past weekend. In his thread back in 2006 titled "Where to get parts for a K&T mill?" he had a very similar issue with the knee. He claimed to have replaced the elevating nut and the problem was corrected. I can't imagine that the nut would have failed already. Any ideas? I will post some pictures of the machine after I unload it this weekend. Thanks, Dan
