If your CAD program won't save .gif, save it in .bmp or jpeg. there are plenty of programs available that will convert these to .gif

Hi Cris:
I was wondering how you made your .gif drawing for your lead screw
setup. Are you making it on a CAD program and converting it somehow
to .gif....very nice drawing especially with the color. Could you
post some of the details on how to make drawings like this.
Thank you:
Wally K.

roughly .05mm preload on the bearings. The retention nut on the end
of the screw is then wound up to hold the whole package together, and
backs the preload off to about .03mm or so.

(Lower torque requirements) I may use a pulley with an integral
collet and grub screws, or do something else cunning, as milling into
a SS shaft is not something I have the gear for.
