Re: Extending cross slide travel -- what is the currently accepted best method?
I didn't move the brass/bronze (?) nut. I 'milled' the slide with my router and left the nut in the original spot. But a split nut sounds like an excellent idea for eliminating/reducing backlash.It

Re: Different Prices - such a range!
Living in Canada, even a mini-lathe was out of my budget range, since there are few low-priced options here. I was lucky to accidentally find a used 7x14 for sale nearby for $500CAD and I grabbed it.

Tony- I just joined this group, so you probably have decided what to do in the month since you posted that question. However, I thought I would add some thoughts as I just completed mods on the

Re: Mods, was Different Prices - such a range!
What is the 0.01 mm spec mean? What is being measured? The cheapest grade of bearing, ABEC-1 is better than 0.01 runout. (it is 0.0075.) Typically machine tools will use ABEC-7 bearing with runout

Re: Mods, was Different Prices - such a range!
I¡¯d want confirmation that it does in fact have tapered roller bearings installed. It¡¯s not that I don¡¯t believe them, it¡¯s that I don¡¯t believe everything just because it says so on the

At that price ($550 US at todays exchange rate ) I am going to take a wild guess and say either a) they mistranslated the Chinese language description or b) they¡¯re lying.

Why bother changing out a gear that works? If it breaks then think about what to replace it with. But you know what? There is a Youtube video with this machinest who uses the name "tubalcain". He
