New cheap linear bearings for hobbyists.

[galaxyman7]

Hi, my name is Colby Lippincott, and I would like to see if anyone is interested in cheap linear bearings, on the order of $15 a piece. I have a CNC milling machine, and I have designed linear bearings that can adjust to fit any circular rail from .25 inch to 2 inch diameter. These can be tightened to increase accuracy. They are face mounted, and have 6 holes. They can be put onto a rail without having to take the rail off. They are made out of high density polyethelene. These are made to be used in pairs, one on either side of the cart for each rail. Leave a post or email me at colbylippincott@gmail.com if you are interested, and I will put however many you need on ebay. It might take me a day or so to make your order, especially for large orders.

Here is a drawing of how it is attached. I will put up actual pictures soon.

I just designed some new linear bearings that will be much smaller and cost about half as much. I will post when I get all of the materials to make them.
