ROCKER CLAMPS
 
COMPLETED
After machining a couple of projects on my new CNC Router I decided I needed a flexible work holding system. After doing some research I found the concept of Rocker Clamps and liked this idea. So not having much luck finding a store to purchase them from it came to me that this is something that would be pretty simple to make using one of my CNC machines. As they were only small items I used my Sherline CNC Mill.
The beauty of these clamps is that one clamp can handle a wide range of material thicknesses with or without a back support block. Setup is much easier than using the step block system and it has a much lower overall profile. One end of my clamps has a cylinder shape and the other a rounded corner square shape, it can be flipped around to suit individual needs. The only addition needed is a range of M6 bolts of various lengths and washers. I only made 4 clamps for the moment as I think this will be enough for the majority of jobs.
The following images show the process. The only stage to go is that I will anodize them.
Used Vectric Aspire to design the clamps
Each clamp is 58.5mm x 17.0mm x12mm
Setup to mill a 6.5mm wide slot
Use CNC to mill the slot.
The finished clamps ready to use.
