This is a 1.25" solid brass rack and pinion type focuser, It was custom machined and is probably over 40 years old. It has large aluminum knobs and three adjustment screws for tension. The focuser has a flat base and the height is adjustable from 1.75" to 2.25" racked in and has 1.75" of travel. I would include a picture but my digital camera bit the dust. Contact me for more information. I am asking $50.00 plus $5.00 shipping, US only.
These are solid machined white nylon, 6 inches in diameter and 1.25 inches thick. They are center drilled to allow for encoder installation and are flat on both sides. Because of the material they are both very strong and yet easy to machine or drill. If you need these to a smaller diameter I am will to machine them at no additional cost once payment is recieved. I am asking $40.00 plus $3.00 shipping, US only
If you buy both the focuser and the side bearings I will pay the shipping.
