Hi,
I have been toying with the idea of making a 2 1/2D cnc router to cut out ribs etc for model airplanes. My thoughts for the slides were hovering around lengths of ground ms bar, the saddles being cut from box-section ms having holes drilled for plastic bearing bushes. I've read around and am trying to determine whether Turcite or Moglice or Delrin would be suitable for the bearing bushes ? I have found Delrin readily on eBay but I know the other two materials are specifically intended to be used in bearings, can anyone say which of these is best in this kind of low load application, and whether the advantages outweigh the convenience of Delrin ? Also a supplier of small quantities in diameters between say an inch and half an inch would be helpful.
Many thanks,
