King Midas mill conversion

[diy-john]

FSI of DFI type that has two fixing holes either side of the flange and 2mm lower profile than the standard FSU type.

Thanks Gary - Please do you know the "height" of the lower-profile ballnut, for a 16mm diameter screw (1605)?
- Have used 40mm in my calculations, thinking might have by coincidence already used a lower profile version(?)
- If one could get 2mm lower than 40mm, then it would be great yes.

With a bit of help from Robin, latest draft -version for X -screw is here:


Total length of screw now is 871mm. (it has grown an extra 290mm from the original plan).

Hope that "custom" screw would not break the bank. (don't know how much extra cost that machining will add on top).
- Have prepared to go "conventional" cuttings, too, if it becomes really dear.
- One facet: want to get the screws as good as possible
- Another facet: being a newbie at this, would be very, very surprised if one gets it right first time round. Not sure how much point there is in paying top money for ballscrews, only to want something else next month. Of course trying very hard to get it right first time, but have to be realistic.

Slowly forward..
