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.

I'll try again to post a pic of my slide mods: Sharp-eyed readers may spot the green masking tape at the left. That's covering an opening where the motor controller box would normally be mounted - I

Re: Free Machining pdfs Available Online
Thanks, Mike. That's an excellent resource. Some of the 'Workshop Practice Series' books from the UK (Tubal Cain and other authors) are there too. John

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

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.

Re: Mods, was Different Prices - such a range!
Anyone have experience of Vevor 7x14 lathe, they state that "Spindle is supported by precision tapered roller bearings, spindle accuracy within 0.01 mm.", so no need of spindle bearing mod?

Re: Mods, was Different Prices - such a range!
Never broke a plastic change gear.? ? My current 7x does not have headstock gears, but never had a problem on a previous 7x with 2-speed headstock.? ? There are many issues with these lathes - the

Re: Mods, was Different Prices - such a range!
Ok, when I talked gears and one breaking it was because I had the lead screw engaged. As my lathe has a brushless motor,? I do not have gears internally for speed changes, etc. I misunderstood the op

Re: Mods, was Different Prices - such a range!
I like plastic change gears. They are more quiet and are the weak link in case of a crash. If adjusted correctly will last forever. I have had the same set for over eleven years.

Re: Mods, was Different Prices - such a range!
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

Re: Mods, was Different Prices - such a range!
Thanks for the comments on the gears. I thought it best to stay with the plastic gears for reasons mentioned in this thread. At some point, I may go with the 16" bed that LMS offers to upgrade my

"Given I said 'buy the cheapest,' I modify that to say, not the HF 7x10" On the other hand, that's what I originally bought and I used it for many years before buying the LMS bed-extension kit. The

Re: Mods, was Different Prices - such a range!
This! the plastic gears are much easier to replace than metal parts of the lathe! In one of his lathe videos Mr Pete mentions this is one reason why they made the change gears for old Atlas lathes out

Given I said "buy the cheapest", I modify that to say, not the HF 7x10 which is really an 7x8 when measured by the method used to spec every other 7x mini-lathe.? ? It is too short and "crowded"
