Welcome to MadModder Jonitus.  Looks like you have got a good start on your first project with getting the lathe sorted out. If you have any questions just ask. There is always someone around to answer or at least give an opinion. Which lathe do you have? Perhaps one of the chaps here have a similar lathe and can help out. I look forward to seeing some of your projects as they develop.  :D :)

Be safe, have fun and enjoy the forum.  :mmr:

Cheers  :beer:

I completely forgot to mention which lathe I purchased.  Oops.  It's a Cummins (Tools Now) 7x12.  I went with that one for the price, as well as it coming with lots of accessories I would have had to buy separately if I went with another company.

Welcome to the collective Jonitus.  :borg:

First let me say that the cross slide backlash is not something to worry that much about. I worked in a large machine shop enviroment and have run large production lathes. They had backlash in the crossslide also. It's something that is inherint in any feed type screw. You will always have backlash. If you don't, the screw will be hard to turn. If you need to make an adjustment on the cross slide you would bring the setting out past the backlash and then back in to the setting you wanted it to be at.

Ya, I know clear as mud, right?

Work on getting the chuck to run true first. That's more important in producing a good part.

Hi Jonitus,

I think some runout (often varying with different diameters of stock) is to be expected with a 3-jaw chuck, especially a budget one. There's one fix here:

Alternatively, if you feel up to it and have access to another lathe, the same effect can be achieved by slightly enlarging the register diameter on the back of the chuck. Then, before finally tightening up the securing nuts, tap it around with a rubber mallet until a dial indicator shows that the work is running true.

There are some good tips on mini-lathe alignment here:
