Dust Collection Vortex Generator

This is a vortex generator for a DIY Dust Collection system.  It is designed to work with standard 1.25" Shop Vac hoses and mounts to the lid of any bucket with a lid.  

Assembly:

• Print top and bottom pieces
• Trace hole at bottom of vortex generator onto bucket lid and cut out the hole making sure no edges protrude to the inside
• Mark the bolt holes onto the lid by tracing the mount holes in the mounting flange of the bottom piece and drill out slightly larger than 5mm
• lay a bead of silicone adhesive on the up facing surface of the bottom piece and then join the top and bottom and squeeze together
• lay a bead of silicone adhesive on the bottom of the flange and bolt to the bucket lid using M5 bolts with washers. (it may be wise to build a backing plate to go inside the lid as some lids are very thin)
• allow to dry 24hrs
• put lid on bucket
• insert vacuum side hose into top hole
• press another hose onto the horizontal inlet
• Turn on vacuum and check for any leaks at mounting point and top/bottom joint
• hook up to tool and turn on vacuum for improved filter life and reduced maintenance!
