Step 1: Materials
I chose to use a lamp nipple for a similar reason. Not only will it make a great small diameter tube for vacuuming, but you can screw things to it to create more attachments.
So now that I've given the rationale for the materials, here is the complete materials list:
- 1 pill bottle with lid
- 1 lamp nipple
- 2 lamp nuts
- E-6000 glue
- 2 cork or rubber pads (optional and not pictured in this step)
Step 2: Tools
- Drill press (hand drill should work fine)
- 3/8" drill bit
- Drill bit sizer
- Dremel with cut off wheel
- Spring clamp
- Utility knife (not pictured)
Step 3: The Bottle
With this mark made I cut along the line using my Dremel and a cut off wheel. When the bottom was removed I cleaned the excess plastic off the edges with a utility knife.
I then tested the fit of the bottle over the end of my Shop-Vac hose. It was a little loose for my taste. The suction of the vacuum would hold it in place, but I wanted it a little snugger. To accomplish this I put two adhesive backed cork pads on the inside of the bottle. This tightened up the fit. (If you don't have little cork pads you could glue some bits of rubber inside the bottle).
Step 4: The Lid
Once the hole is drilled thread one of the lamp nuts onto the nipple. Press the nipple up through the hole in the lid. Smear some E-6000 around the nipple where it protrudes through the lid. Then thread the second nut onto the nipple and tighten it down into the glue.
Once the glue has dried put the lid on the bottle and you are ready to vacuum.
Step 5: Simple Extension (added 9/26/2009)
To make this extension you simply screw the coupler onto the base until it stops. Then screw the longer piece of lamp nipple into the coupler. See pictures below.
