    Re: Bridgeport ballscrew retrofit, design the yoke

    Hello darco30

    I rely on this drawing
    The most important measure is the distance between the axes (101.6 mm) .
    The rest is adapted to the screw you intend to use .

    Hope I helped

    Re: Bridgeport ballscrew retrofit, design the yoke

    very nice drawing , where did you get it?
    thank you for the drawing it will be so useful to me.

    As i can see , the yoke bore is 42mm, and the chinese 32mm 5 mm pitch ball nut has 50mm pilot diameter. Thats why i still think the 32mm chinese nut wont fit.. as i said earlier the z axis bearing housing will be in interference with the nut.
