Having trouble after QCTP install.

Those parts look just like mine. If the gib wasn't parallel to the bottom surface of the ways, then it wasn't assembled correctly. I wish I had a photo of mine to post, but I neglected to take any of that part of the assembly/disassembly process. :hate:
 
I believe I have that figured out. I did grind one side of the round spacer to add some relief so it would sit flush on the gib. I reassembled it and all seems MUCH MUCH better! I need to figure out a good way/gib oil for this lathe. I have all kinds of automotive oils on hand and some cutting oil but I will have to go buy whatever is needed. Any suggestions? Something I can purchase either from a napa, a bearing supply house or amazon would be helpful. OH YEAH, I believe I may have gotten to the bottom of the chuck problem also. When I took the 3 jaw off, I must have layed it down on something that stuck to the back of it (think grease), I have not tried it yet but I did scrape off a pretty long sliver of it. I cleaned the threads (inside and out) again and oiled the threads with assembly lube and reinstaled the chuck. When I first removed it, it appeared to have anti-sieze in the threads-- is that better than oil for this application? I would think it could cause problems..

I will try to find some of that. I now have the saddle tight to the ways, seems to have no movement. Still seem to be having the same chatter as before. Now that everything is square there I will go back and re-read all the other suggestions and start on those. Cant tell any difference on the chuck, still wobbles-- That cant be good. I am going to have to start making some progress soon or this thing will be scrap..

Parts are correct. You have the older carriage (vs the exploded diagram) its actually part #168.

Were those notches against the carriage or against the gib? Based on the grime it looks like the notch may have been against the carriage. If so, I believe that is upside down. I think the notch goes toward the gib side, so that the spacer can sit flat on the gib (notch goes over the hump on the gib ... if I remember).

Ahh ... I posted before I saw page #2.

Good on reading back through the other posts. Things to rule out and make better (probably a combination). You will get there, no need to write it off as scrap.

In the time being any oil is better than no oil.
 
From the lack of visible wear on the front hold down, it would appear that around 1/8" vertical lift or clearance is normal on that machine.

EDIT: Well, maybe not. What do you get when you assemble it as Ed wrote?
 
When properly assembled I get ZERO lift. Everything now seems tight, I am making progress so far not towards a scrap run.. lol

OK. That makes more sense. But I've learned not to be too surprised when things don't. ;)
 
OK more progress made. I believe my biggest issue was SPEED, pure and simple RPMs. I recently got the dual speed pulley bushed up and installed correctly and I have determined that the slower speed there and the bottom 2 speeds on the flat belt work the best for the steel I am cutting. I can speed up to the highest flat belt speed when I done and take a "polishing" cut and its fine. I may or may not have the correct motor pulley, but I can tell now that for most of the things I want to have the ability to do low speed will be used. I do wonder how I am going to use the live center when I have to work close to it with this new tool post. It seens as tho I will have to allow the cutting tool to protrude more that I am currently doing, although I may be overdoing it with my closeness to the toolpost. How far out is too far out? I really need a machinery's handbook, how much better is the new one vs an older copy?

Thanks again for all the help!
