I am having trouble after installing my QCTP. I used the lathe and a 4 jaw chuck to cut the t-nut for this new setup (just faced the plate down and then cut the sides with a band saw to fit). Other than the old toolpost slipping, and not having the correct angle holder it worked fine. These are the reasons I am replacing the tool post, I was apparently using mis matched stuff and was missing some shims. I know NOTHING about being a machinist, but it was working fine before and now it seems to be going crazy. I have some steel rod that I have been turning down just practicing on and I was cutting nice little spirals of material off, and leaving a fairly decent finish, now it seems like I am making ez-outs! Thats what it looks like anyway. Also the machine is making a chattering noise, the headstock seems as tight as new, and nothing seems to have changed. I still dont have the machine bolted to the floor (keep forgetting to grab a concrete bit), but it wasnt before either! I made new tools, more correct tools, tried using some tools with carbide cutters, tried different speeds ETC. I have no idea what to do next. Maybe something has slipped in the 3 jaw and it has a lot of runout, I guess maybe I should try to find a test bar. Any ideas? I will try to take a picture of what I have going on.
