First time build - Steel Frame CNC Router

[examorph]

Dean - Cheers again for the help, good to know I can cut thru 10mm steel plate simply with an angle grinder! I haven't ordered anything yet so good spot on the motor, will get in the 6.1Nm to be on the safe side. Do you have any recommended suppliers as I dont think CNC4You do this and also, will it work fine with AM882 Drives?
I lifted up the spindle slightly but think this, like many other things might have to be one which gets put right during the build.
Attachment 17430
Do you think I am in a position now where I can start getting some of the linear motion stuff in from Fred Lee and start looking at local suppliers for the frame materials? If so, could you please cast your eye over the below list to make sure I haven't cocked anything up?

Linear Rail -
2 x Hiwin HGR20- 300mm linear rail
2 x Hiwin HGR20- 600mm linear rail
2 x Hiwin HGR20- 1000mm linear rail
12 x HGH20CAZ0C Hiwin block

Ballscrew -
1 x SFU / RM 1605-L250mm Overall length- C7 ballscrew with a ballnut with end machined and increase dimension F on end machining to 25mm for pulley
1 x SFU / RM 1610-L650mm Overall length- C7 ballscrew with a ballnut with end machined and increase dimension F on end machining to 25mm for pulley
2 x SFU / RM 1610-L1050mm Overall length- C7 ballscrew with a ballnut with end machined and increase dimension F on end machining to 25mm for pulley
4 x BK / BF 12 support for ballscrew


Some things I am not too sure about are if the reference is right for the narrower carriages, if the Z0 pre-load is what is normally gone for and also if the end machining info is right?
