I had bought this kit from Swarf Rat way back when and they only sent me the clamp system along with the drawings for the brackets...

I never got around to machine them and now decided to print it out. Turns out it wasn’t a good fit for this clamp. Go figure, since this clamp came from them!?

So I modified it a little and now it fits perfectly. In case you have the same clamp as I do, maybe this will work for you too.

UPDATE: Added a bottom v2 where the bottom of the thumb screw is recessed in to allow for more screw travel.
