Finished my dip handles and made up a calf block/platform as well. Have not done any dips for about 4 months so its gonna hurt.
I made the Dip handles out of 40mm solid round bar. At the face of the rack the handles are 450mm apart and V taper out to 600mm.
I have machined up a couple of Stainless Steel spindle locks that secure the Unit to the main power rack. The rest of the steel used is 75x50x3 mm thick mild steel.
This is a solid unit that will take a hammering.
