Hi!
I'm looking to purchase hardware for my first router build.
I want something fairly rigid, that will handle aluminium and some soft metals. I will go for a gantry set up and probably end up copying allot from others.

I plan on designing the mill in Inventor, but before I do that I need to decide on what hardware to go for.

I watched a review by David Burrell, where he looked the ballscrews from China that are available on Ebay. He gave them good remarks, so I thought I would just buy a set of those including sbr20 linear rails.

Is this good choice? I would love some feedback on this selection.

To drive the mill, I was thinking about going for a 4 axis set from cncrouterparts. It looks like a decent price to me and gives me a chance to add the 4th axis later on.

I plan to make the purchase later this week, so I can start designing my mill soon.

Thanks for your help !
