Bloody hell not often Jonathan and me agree but he's spot on..:tup: . . . You completely missed the point.! This is not an attack on you personally more on the results of your comments.!!

Nobodys asking for lies and I appreciate the dissapointment when things arrive damaged but comments like "spaghetti screws" does put people off. I know this for a fact because I get absolutly loads of folks contacting me asking for advice or re assurence because they've read comments like this which then muddy's the water and sends there brains into melt down.!!
It's like my comment about the VFD's, yes in reply to you I haven't said this because it wasn't the matter of the subject, but when folks do ask I clarify why I'm not keen but I also say say they work fine if you get a good one.
To be honest my point of view regards them is changing because they seem to be getting better, but in the early days it was a lottery if you got a good one and if you did how long it would last.? Also the price differnce between buying one without or one with VFD has gotten so small it's a chance worth taking. (Thats why I've just ordered 2 sets.!!)

I also wouldn't expect anyone buying cheap ballscrews from china to expect tolerences down to sub micron level just like I don't expect you have them down to that after you got them straight-er.!!
You get what you pay for thats for sure but if what you get is good enough for the job then happy days. ..
