I'd love to, but although the HiWin rail is not too badly priced, the bearing blocks are very costly. Are there no alternative brands who make them to fit the same rail?

[Swarfing]

Mmmmm sower grapes me thinks????....I love my unsupported rail and never had a problem, maybe that is just me :-)

Reality is you get what you pay for in most cases, if you can afford profile rails and bearings then grab them first. If you can not then anything else needs to be as thick as you can afford to give yourself a chance.

After I looked more carefully at the parts I found one rail was strange, it seemed like it was slightly more narrow at one end because regardless of the bearings used, it was tight at one end and sloppy at the other. So it isn't the bearings so much as a strange rail.

I sent a short video to the guys at CNC 4 U and they called me back to say they are checking their stock and if others are okay they will send me a replacement, without me even needing to return the duff one.

Robin,

You can also get the flush plugs for rails mounting from the front and SBC rail might offer a few different options, then there is going over to traceparts and looking up the French/Swiss rails (not much different in price from Hiwin from what I have seen) and seeing what they offer as well. I need to look up th Italian firm that sells different types of rail on the per project basis as most want you to buy way to much. Good luck

Hi Jonathan you PM box is full.

I'm about to buy the ballscrews from Chai. Just to be sure, I need to get the ballnuts from him right? They are not part of the mount. Also, if he sends me the twin-start thread like he did to Jazz recently, will it work okay for the nut-mounts?

Sorry I didn't realise - sorted now.

Yes you do need to get the ballnuts. I recently got some of the twin start from him and I think they will be more rigid than the single start. I asked for twin-start and the price was the same...rotating ballnut mounts will work just fine with both.

I cut a few bits of 16mm aluminium to size today for the Z axis.

[Jonathan]

Is the watering can your coolant system?

[Tenson]

Yes it is. I have never needed it before to cut wood (obviously) but I found my scissors got quite hot cutting the 16mm aluminium. I made a coolant drip with a thin bit of tube and siphon effect.
