1. Put tube (solid wall type of tube eg. poly pipe for dripper etc.) in=20 hole, 2. Attach tube to suitable container, 3. Attach vacuum to same suitable container, 4. Drill (cut or otherwise) a suitable size hole to allow vacuum to be=20 varied eg. inch hole, 5. block hole as needed to allow vacuum motor to still create enough=20 suction, 6. Bearing will suck to end of tube, if careful (I have needed to=20 similar before), 7. Slowly and carefully pull out tube with vacuum running, with desired=20 hole blocked as required. Good luck!!
