Description
A dust blower for the installation of chemical bolts, concrete anchors and climbing bolts.
You will also need a PVC pipe 50mm diameter and an aluminum rod of 16mm diameter, the length of the blower is up to you. My one is 27 cm long (PVC pipe).
Use a hot glue gun and PVC glue to connect the parts together.
Try to scale up the piston by small increment to get the perfect fit for your PVC pipe.
Use silicon lubricant spray inside the PVC pipe to reduce friction.
