I considered buying them, for about 20 seconds.
The only thing this size ballscrew is good for is maybe a big milling machine or lathe. For other machines, like CNC routers, the forces on the ballscrews are so low that you don't need the slight increase in stiffness gained from using a RM2005 screw, hence you're much better off sticking with 16mm ballscrews and the appropriate pitch. The price was good, but to me that's not enough to counter the poor performance you'll get on a router with these, especially since it could increase the cost of the electrical parts. Presumably John S has a big machine to convert...

( That Old bastards not about any more and he's still beating me to it.!! )

Hmm really?

Or for replacing a worn ballscrew on a machine of a very similar size like mine.!!!

Perhaps, but we both know you'd me much better off getting 1610 or 2010 for a router this size. 325 USD including postage (but not customs) gets you two RM2010-1500mm, so yes a bit more but well worth the extra money if you are swapping since you can keep the same end-machining, unlike with 1610. Wearing out the ballscrew would take some doing anyway, I gather it's generally the nuts that fail first.

Got two RM2010 at 1450mm with end machining and ballnuts from chai for $218 including shipping. So 325 is very expensive where ever your buying those from.

Forgot who your talking to here Numb nuts.? . . . . What you think you know your wrong about.!!

This machine has been working fine for nearly 5 years with 2005 and the wear is very slight and possibly in the nut, could even be end bearings I haven't checked yet. Mostly it's down to the fact it's been abused and abused with no protection and run in some shity conditions.!!. . . . . 1610 or 2010 would give me nothing extra I have already that is of any use to me so why would I bother changing now.

It would just have been nice to have had the chance to buy some cheap replacement screws before being offered up to general public considering the involvement I've had with this machine.!! . . . ANT.

You need to take everything though, I'm not pissing about wasting diesel to pick 10 bobs worth of gear up.

Cheer's John. I understand its not worth the trip just for the Z axis so no problem. I'll wait to hear from Jazz and see if he want these screws. If not you can still have them mate.

Come on Lee, been back two minutes and you are already wielding the red pen.
It was a joke for Christ sake, Jazz even called himself a fat bastard in the post about the Aztec calendar, why don't you edit that ??
