Just letting everyone know that our 20mm and 30mm SBR supported rails and bearings are now in stock at http://www.glacern.com/sbr.
They are currently at winter sale prices, and we're offering $4.99 flat shipping for orders over $99. We also have 30mm x 10 ft rails in stock, which ship by truck freight.
These are first of many automation products that we plan to add to our catalog. We're particularly excited about these rails, as we feel they're ideal for folks building their own routers and plasma tables thanks to the low cost, availability, and ease of installation.
We're fans of using aluminum T-slot extrusions for building CNCs since they're so easy to cut, join, and adjust. Our 20mm rails can be bolted directly to standard 60mm-wide aluminum extrusions (30mm T-slot spacing) without modification, while the 30mm rails can be bolted to standard 80mm-wide aluminum extrusions (40mm T-slot spacing). Likewise, the 20mm and 30mm rails can be adapted to "10 series" and "15 series" inch extrusions by simply drilling additional holes in the extruded aluminum T-support.
