Hi Eling,
Sorry my progress is so slow. I tend to get sidetracked, so my projects take long paths to completion.
In the first post their is a link to the woodworking forum thread where Simco posted his original design. In that thread there is detailed advice about making it, mods for more capacity, and photos of two built brakes.
I suggest you sign up to that forum (it uses the same PHP forum engine as this one, so it works just like CNCzone).
