I'm working on converting my 20" Push-To Dob to the OnStep Go-To system. I need to reduce the torque to move the Altitude bearing. The existing 4 teflon pads require too much torque for the NEAM 17 stepper motor to handle based on my measurements made with a digital scale. I am looking into using two of these liner glide bearings made out of nylon. The bearings are the right width and with 1/16" shims on the sides, the correct height to match the remaining teflon pads heights. They would need to be cut to the proper length (come 75mm long). Do you think the nylon has the strength not to deform under the weight of the fully assembled Dob?
