Look what i did with mine a couples of days ago.

They are the same size as the robart 630 series, but stronger. Made with 1/8 thickness instead of 3/16 and will have a trunion made with 7000 serie aluminium instead of 6000.

I want to hit the market after Xmas. 125$ to 150$ for a set of 3. It's the first proto, the finish is not good but they will be anodized anyway.

Programmed directly in G codes. I'm using CatiaV5 for more complex design. Done on a Republic Lagun 4 axis mill.
