Step 1: Drill Holes

Set the drill on a low speed. Use a 3/8" drill bit to drill holes in the bottom of the aspirin bottle. After drilling, clean out the plastic shavings.

Step 2: Attach the Tubing

Fit one end of a 3/8" piece of flexible tubing into one hole. Fit the end of the other 3/8" piece of tubing into the second hole.

To make sure the tubing is air-tight inside the bottle, apply silicone caulk around the margins of the holes in the aspirin bottle.

Step 3: Attach the Vacuum and Bottle

Use duct tape to secure the end of the vacuum hose to the top of the aspirin bottle (Image 1).

Extend the two tubes from the bottle to the cutting blade area (Image 2). Secure the tubes with electrical-cable clamps.
