Hi graham here. i'm from just out side newcastle
so i've found this place as i'v a viceroy tds 11gb metric lathe i'm wanting to convert to cnc! i have looked at doing this a while ago 06/07 but the price was still alot more than i was willing to pay, but now things are a lot better now..

now what i'm wanting to do it for is so i can cut both metric and inch threads with out the carry on of having to power the lathe back and forth all the time. but tbh thats not the real problem, unlike boxford lathes where you can buy the charge gears an parts with easy, you'd be looky to find the same ones i have on the lathe now, or i could get them made but the cost of doing so would run at£1000 easy and then i'd only beable to cut a few threads,
plus the fact all the things i could make that i could not as it is as a manual.

so i'm looking for bit help on what to get, as i've been reading up alot and its got my mind mashed up!

so far i'm thinking of a 425oz nema 23 motor for the x axis. might be geared down to 2.1 plus i don't want it sticking out to far as space is tight..
and 906oz nema34 motor for the z axis
and a The SF1605x1100 machined ball screw for z axis and that £52.60
The SF1605x400 machined ball screw xaxis as thats £38.60 plus cost to buy the screws and mounts and so on,
i'm unsure on what drvers and borad to use, i don't want to spend a bomb on it??

the other main problem i am going to have is how do you mount the ballscrew on the z axis under the cross slide, as i think i'v only got 30mm max.. will check tomorrow..
