Step 1
Wrap the towel around the middle of the broom handle.
Step 2
Place the middle of the broom handle, wrapped in the towel, into the vise. Close the vise until the broom handle is held securely. Do not over-tighten the vise or you risk cracking the wood.
Step 3
Place the die over the bottom end of the broom handle. Grasp the handles of the die and rotate the die clockwise, twisting the die down onto the shaft.
Step 4
Continue twisting the die onto the broom handle until the die has cut the threads to a sufficient depth to accept the broom head.
