Denford Easimill restoration and upgrades

[Jonathan]

Are you planning on putting a braked motor on the knee?

For now I just have a 12Nm stepper that's been kicking around. That's plenty to hold it while switched on so I guess there's not much call for a brake? There is a rear shaft on the motor, so I could probably devise something.

I've got a 700mm total length 25mm x 10 Ground Comtop with soft ends ready for machining which I think are C3 if not then Def C5 which I bought from Jenatec years ago. I've actually got 3 in total all different lengths, this is shortest, others are 950, 1100mm the longest one got a preloaded double nut. I Will sell them as a set for £300 + shipping.

The ballscrew lengths that the machine currently has are X=936, Y=452 and I'm planning Z=585mm, so your set would be close to ideal except I'm not quite convinced by them being 10mm pitch as opposed to 5mm. Do you have the part number for the ballnuts to hand so I can compare their stiffness values?
