Now we're down to the good stuff!
To the right, my micro block vise and it's accessories (the vise is the hand that holds the work, the accessories are the fingers). You can use whatever vise you want but since I had this one and it's small and light enough...
To the left is the foot pedal, the 20oz CO2 tank (theoretically meant for paintball), and the regulator. You can get a glimpse of the brackets I added to keep the important things from moving around.
Note: If you want even more portable you could go with Steve's PalmGraver and not have the foot pedal to deal with.
