I don't know Kevin but Fred is a reliable seller.

You want to know that if something isn't right that they will sort it out. Having bought from China a few times now - Fred has been the most hassle free. One faulty item out of 18 and he sent a replacement a few days later with no quibbles.
The 2m ballscrew was packed very well. It was supported at the bottom with a plywood plank. I know fred puts them in a box. Next time I order I will definitely go with him. Plus, his English is excellent compared to what I've seen on AliExpress so far :D
Good Morning. How is the build coming on.
Just to let you know, I have used the Chinese SBR rail and guide. 1000mm long.
Been in use some 18 months now. Faultless operation, I have had no trouble at all.http://g02.a.alicdn.com/kf/HTB1nvRMI...pg_120x120.jpg
The rail is supported, so why in your drawings is it not?
I have attached a quick photo from an Ali site, just to confirm the style of rail that you are using.
I just happened on this site, and I am curious, as to how you got on.
Cheers,
