...guy building a cnc router and he used rubber hose and hose clamps to connect his steppers to the lead screws. Just wow. Yup, I did the same thing on my 1st router back in the late 90's. 1/4" lead screws, 6mm fuel injection hose from the auto shop where I worked. Put the hose on as a tempora...

$10.00 says Dave lines up his house shoes exactly 90 deg. to the bed rail before going to sleep! :lol:
