Hello

[JoeHarris]

Thanks for the advice it is very mush appreciated, I am getting the message that if buying from china I should go with Chai but for your information the listing I having been looking at is http://www.ebay.com/itm/300652998890...ht_3739wt_1037

£400 seemed good for this lot and the ball screws for the X and Y axis are 20mm so whipping should be reduced?

Another question, to make the ball nut housing - if I cut a 36mm hole with a holesaw on my pillar drill into aluminium plate will this be accurate enough or am I best to fork out on ready made ones at £40 a go? (http://www.zappautomation.co.uk/mdg2...ing-p-464.html)
