Lock Jaw collar and inner collet for Half Inch PVC for use as a dumbbell

For the lock jaw you're going to need...

M3x20mm bolts x 3

M3 nuts x3

1 pin that is about 3mm dia x 20mm (I used a scrap steel pin wrapped in tape to get a tight fit)

duct tape/electrical tape (for pads for extra grip)

For the pads I used two little squares of double layered duct tape. Could use more layers if you need to for a better clamp

For the inner collets you're going to need...

M4x15mm bolts x2

M4 nuts x2

Duct tape for inner faces for extra grip
