1. I read the hiwin maual and it says ( for carriages lubrcation ) to use lithium soap base grease. Is tha a MUST or i could use oil ( and what oil ) instead of grease.
2. Do we also lubricate the rails or only the carriages?

1. I think if you use grease then the lithium is a must, but oil can be used, Jonathan used it here for example; http://www.mycncuk.com/threads/6484-...strong-machine
I get the correct grease here; http://www.toolstation.com/shop/Auto...se+400g/p89691
2. Lubricate the carriages only, they will pass lubrication onto the rails.

#3
When we use the epoxy method we first drill then tap then close the holes and then apply epoxy or we apply epoxy then drill and tap?
#4
What is the right angle to hold a single beveled straight edge? 90 degrees?45? something else?

3. I drilled and tapped all the holes after I poured the epoxy, there were no problems by doing this.
4. 90 degrees because you do not want the straight edge to bend in the middle.
