3 SBR16 sets +3 ballscrews RM1605+3BK/BF12 +3 couplers | eBay (http://www.ebay.co.uk/itm/3-SBR16-sets-3-ballscrews-RM1605-3BK-BF12-3-couplers-/250476169366?pt=LH_DefaultDomain_0&hash=item3a518b0896)

Is it a good price? I want to build a machine around these sizes so it seems ideal.

I already have spindle, steppers and electronics and I plan on building a steel box frame. What else do I need, Is it ok to use steelbox for the gantry too?

I like the look of this machine and plan on using it for reference :)

This is the eBay seller to use, he is called chai - but my advice would be get the design of your machine straight then email him directly with the exact sizes you need. He makes to order and will give a better price...

Joe's exactly right. I wish Chai would stop listing those 'kits' as they're almost invariably mismatched, causing people to end up with a sub-optimal combination. When the machine is designed you'll know exactly what length ballscrews and rails to get. Only then should you buy them. Send the seller a message listing exactly the sizes you need and he'll give you his 'best price'(!)

But Philly remember the old adage Measure twice, cut once you will save yourself s and hours of grief if you design it first..
In doing my design, I really learnt how to use the solid modelling features of my CAD package (TurboCAD Platinum 15) and I was able to share the design with my cousin who is a professional engineer using Catia!

Good Luck
Mike
