After searching all over the web and on Ebay for linear bearings, I became disgusted with the price. I can't believe that even used, banged up bearings are selling for such a huge price. So, I set out to make my own and offer these to other home cnc enthusiasts who want a bearing that is cost effective, comparable to commercial linear bearings in smoothness, and is rebuildable to increase the lifespan and versatility of the bearing.
A 3d model of the part that had me stumped for so many months. It seems so simple now...

Here is what I learned and how I built the HBLB.
