Introduction: Building a Capsule Quick Filler
*BE SURE TO ENLARGE IMAGES AS THEY CONTAIN INFORMATION BOXES*
This guide shows you how to construct a device that greatly reduces the time and ease of trying to fill gelatin capsules. The only decent capsule fillers on market is a CapemQuik machine' it does work but it's inefficient can only do bulk loads and is very time consuming. So I constructed a quick filling machine. It can fill 4 capsules at a time and do around 12-24 per minute depending on your speed. The tubes that hold the capsules can be cut as to allow for different fill levels.
1. Medication bottle with lid, the wide ones work best
2. Basic Bic pen, the type with a hollow tube
3. Dremel with cutting, drilling and routing bits or equivalent
Step 1: Measuring and Marking Your Drill Points
We need to drill the holes for the lid. This can be done many ways either by hot nail, drill, and so on. But first use a ruler to mark lines running from top to bottom on the lid; then make two diagonal lines.
We need to mark the drill points. I would recommend drawing four 'X's, mark one on every other line about 1/4" from the edge.
Create a starter hole by punching through the lid with a pointed tip; just a small hole will do.
Using a routing bit a cut a hole about 1/8" to 1/16" smaller than the diameter of the filler tubes; if done correctly the joint will be tight and sealed.
The measurement lines can easily be removed by either using a solvent or sanding.
Step 2: Cutting the Tubes
Converting a Bic pen shell into filler tubes
Remove the end cap of the pen and then pull out the ink tube and tip from the front, this should leave you with an empty tube.
Using a ruler divide the pen into four sections and mark your cut lines.
Now using a Dremel cutting wheel or another tool make your cuts.
You should have 4 same length tubes with rough edges which can be removed by sanding.
Now we need to sand the tubes top sections to allow a capsule to fit over top.
Start by marking the line where you want the capsule to stop with a sharpie
Now gradually sand the tube so that it is thinner at the top and thickest where you want the cap to stop.
Take your time on this step as mistakes take time to fix :(
Once all edges are smooth and flat and they are about same length you can begin drilling the holes in the lid.
Be sure to test the fit before moving on, you want a very tight fit that holds the tubules snug.
Step 3: Ging the Tubes "lip"
To stop the tubes from just sliding out of the lid we will need to add a flange to each tube. A flange is an external ridge, or rim that will prevent the tubes from pulling through the lid. This can be done by heating up the plastic tube then forcefully pressing it against a flat surface
If done correctly you should have a lip just big enough to keep the tubes from pulling out.
Step 4: Assembly and Leak Checking
Go ahead and put the device together, to check for leaks you can use baking soda. Just pour in baking soda till 3/4 full then shake (with capsules covering ports), You should see a small amount of powder but nothing to worry about. If you see a lot of powder then you have a leak.
Step 5: Learning to Use the Capsule Filler
Using the device is fairly easy and quick. Add a capsule to each filler tube and adjust level and snugness
turn your device upside down and tap the bottom causing the capsules to fill up.
Once all four capsules are filled as wanted lay the device on its side in a position where it doesn't roll.
Remove one cap at a time and then replace with a new cap, rotate and repeat.
Keep a piece of paper or something to catch the extra as not to waste it
