Taig Lathe Cross Slide Problem

Bought a Taig lathe about six months ago. I am a little dissapointed
in the quality, particularly the cross slide. It binds as you turn the
dial. Looks like the piece that the lead screw threads into may be
cocked? Not sure. Also, very poor instructions came with this lathe.
Anyone have similar experience?

Did you buy the assembled lathe or the kit?
The kit requires a little fitting and running in (thats why it is a kit). On mine, I experienced a similar issue until I removed the cross slide and looked at the brass nut underneath. There was a little burr that caused it to bind up in the hole it sits in. Since it couldn't pivot to take up runout in the leadscrew, it felt like it was binding. I cleaned it up a touch and that fixed the problem.
The other possibility is that you have the gibs too tight.
If you are a little dissapointed with the Taig, you would probably be mortified with anything else in the same price range. Once set up and adjusted propperly, the Taig will do very nice work for a long time.

Actually, the brass nut on my is jammed. Should I attempt to free it up? Not sure how to do that. I looked at that nut I thought that could be the problem. Also, my was not a kit, it was assembled. Bought the milling attacment as well.

[Most people seem to be pretty happy with their Taig equipment. It sounds like your lathe is out of adjustment. Unlike much equipment in its price range, these tools are made in the USA. If you have a problem, you can contact them; they provide excellent free technical support. I'm sure they can talk you through the adjustment process, and get your cross-slide working smoothly. You can call them at 480.895.6978. If it's still under warranty, which would be the case if you bought it new, they will replace any defective parts for free. If you want detailed instructions on setting up and running your lathe, I'd suggest you purchase Tony Jeffries' book, "The Taig Lathe", available from the Taig site:

Follow the suggestions given by the other followups. It is almost certainly just a matter of adjustment. Or perhaps some chips from previous cutting operations have gotten wedged in the threads of the nut.
BTW The gibs *should* be tight enough so the setting won't shift as you move the other axis, so it may be that you are expecting it to be less effort than is normal. If the gibs are too lose, you will get chatter, and the settings will change while you're cutting.
I have *never* seen what I would call "good" instructions coming with a lathe. The assumption is always that you already know how to use a lathe, and they instructions focus on controls which might be different from other lathes. As the Taig is a very simple lathe, I would expect very little in instructions. (IIRC, there were *no* instructions with mine, from quite a few years ago.)
FWIW The best instructions that I have seen came with the Unimat SL-1000 (which was expecting users with no previous experience).
Other than that -- two of the lathe makers (South Bend and Atlas) have published a "How to (use/run) a lathe" books which were often shipped with their machines for the novice user, and which are still available in reprints or NOS (New Old Stock) copies, and which are very instructive. None of these focus on an individual lathe in the maker's line, but rather on the general principles -- except perhaps for charts for threading gears for those lathes which come with individual change gears.
No -- other than the minimal instructions. But -- I did not *expect* any more. I already knew how to use a lathe, and had experience with several sizes.
Good Luck, DoN.

If you bought the assembled version your should contact your dealer first, to see what they say. That said, often there is a little stiffness in the crosslide at first until the parts wear in. You need to lube it and make sure the gibs are adjusted. The nut can be adjusted with a pair of pliers, rotating it so it lines up with the ways. I often find that lapping in the screw/bearing interface will clear up any roughness as well. Subscribe to the taigtools yahoogroup for lots of good advice about the lathe, pretty much everyone who has one is subscribed there.
