Introduction: Old Paint Can Secret Stash

About: I've always liked pulling things apart - it's the putting back together again that I have some issues with.

I recently made a secret stash out of a WD40 can which worked out really well. In the comments someone mentioned that a spray paint can – all old and crummy would be a great alternative to the WD40 can. I thought that this was a pretty good idea so instead of using a spray can, I used an old, crappy tin of paint that had been sitting around my shed for a couple of years.

There are a couple of benefits on using a paint can over a spray can that I can see. Someone else in the comments mentioned that they had their shed broken into and all that was taken was the spray cans. Guess some kids wanted to do some tagging. The other benefit is that 90mm pluming parts fit nearly perfectly into the can, making the job pretty straight forward.

I also made a “how to” video so if you can’t be asked reading the ‘ible, then just watch the video

Step 1: Parts and Tools

All of the PVC parts can be found at any hardware store. I have added links to Bunnings, an Australian hardware chain so you can easily identify the plumbing parts

Parts:

1. 1 litre paint can – preferably well used

2. 90mm threaded coupling - Bunnings

3. 90mm screw cap - Bunnings

4. 90mm push on cap - Bunnings

5. 90mm PVC tube - Bunnings

Tools

1. Dremmel with a cutting wheel attached. You could also use an angle grinder with a thin cutting wheel.

2. Clothes to clean the inside of the can

3. Super glue

4. Epoxy glue

5. Belt Sander (you can substitute this with files and sandpaper

6. Sandpaper

7. Hole saw. I think it was about 80mm diameter.

Step 2: Cleaning the Can

Actually, you only want to give the inside a clean and remove any excess paint inside. The dirtier the can the better!

Steps:

1. Empty the can of any paint that might be inside

2. Wash out the excess paint with some water

3. With a cloth, dry and wipe the inside of the can and the lid to remove any last traces of paint

Step 3: Cut the Bottom Off the Can

Steps:

1. Make sure that the can is secured well before you start to cut. I placed mine in an open vice (but didn’t close it around the can) so I could easily turn it and also keep it secure

2. Use a dremel with a cutting wheel to carefully go around the bottom of the can. Don’t cut right on the lip of the bottom of the can or you will go through the bottom. Give yourself a couple of millimetres above the lip when cutting

3. Keep on moving the can around slowly until you have cut the bottom off the can

**Be careful here as the can will be sharp and it is very easy to cut yourself**

Step 4: Sanding the Can and Super-gluing the Lid

Both the can and the bottom section will be very sharp so it is important that you remove the burrs and give the edges a sand to remove any danger of cutting yourself

Steps:

1. Place the end of the can on a belt sander and carefully sand down the edges. This also has an added benefit of straightening up the cut that you made.

2. Keep turning the can around making sure that all of the edges have been sanded and that the end is flat

3. Next thing to do is to remove any pieces of metal on the bottom of the can. You can also use the belt sander to remove these as well. Just hold the bottom at an angle to the belt sander and remove any leftover can from the lip.

4. Use some sandpaper (I used 400 grit) to finish off the edge and remove any last burrs or sharp edges.

5. Lastly, super glue the lid onto the can.

Step 5: Adding the Screw Cap to the Can

You need to remove the middle from the cap so only the thread section remains. I found the easiest way to do this was with a hole saw

Steps:

1. Attach a hole saw that is a little smaller in diameter then the screw cap.

2. Place the cap in a vice and drill out the middle section

3. You will need to sand the inside of the cap to make sure that you remove the plastic left inside and to smooth it out

4. Around the edges of the cap are small ridges for grip. You will need to sand these down in order for the cap to fit inside the can. Don’t totally remove them but just reduce their size with the belt sander

5. Test to make sure it fits inside the can. It should be a nice, snug fit.

6. Add some epoxy around the edges and glue into place. It should sit around 5mm inside the can

Step 6: Adding the Bottom to the Coupling

To ensure that the bottom section of the can is sitting correctly and it is screwed into place, you need to do the following

Steps:

1. First, screw the coupling into the cap section in the bottom of the can. Make sure you don’t screw it all the way as it needs to sit on the bottom of the can when gluing.

2. Add some epoxy around the bottom rim of the coupling where it will sit against the bottom of the can.

3. Put the bottom of the can on a flat area and place the can on top of it. You may have to adjust the coupling until the bottom of the can is sitting flush

4. Leave to dry for a good hour or so.

5. Test to make sure that the bottom screws into the can and everything is working as it should. You may have to add some more epoxy around the coupling and bottom of the can.

Step 7: Adding Some PVC Tube for the Container

Steps:

1. Cut a piece of 90mm tube so it fits inside the can once placed into the coupling.

2. I also added a cap to the top of the tube for added safety. The cap is quite loose so secure it down by adding some electrical tape around the tube which will act like a seal.

That’s it! Pretty simple really. When you add it to a shelf in the garage with all of the other used paint cans, no-one’s ever going suspect that there is a stash of goodies inside.

    For Step 3 I recommend using a can opener (electric or manual) that uses an edge cutting wheel that leaves a smooth edge. I use this type of can opener for dog food so I can use clean dog food cans to stash safely, since who could guess that dog food will hold precious stuff inside?

    Dog food can is perfect for a secret stash - and you can just store it in the cupboard somewhere. I did think about using a can opener but I was worried about turning the edge of the can in and having issues later adding the coupling.

    Some of the high quality paint brands, such as Behr which is sold at Home depot, use plastic paint cans. This will make cutting and preparing the paint can easier and safer.

    Yeah - if you can get plastic cans then these would be a great alternative

    Great 'ible. 90mm fittings aren't easy to find in the UK, standard drainage looks to be 110mm

    I reckon you should be able to find something to fit. I'd just measure the plumbing parts needed against a can of paint to work out what is the best size to use.

    Rookie question here: does anyone know if SAE (non-metric) fittings will work in these cans as well? Lonesoulsurfer recommends 90mm PVC but I don't know if the American Home Depots carry those.

    Anyone?

    1 reply

    If you convert 90mm to imperial then you would need 3 1/2" couplings. I'm not too sure if you can get them in that size though in the US. I checked out Home Depo and couldn't find any. I found 4" which will probably be too big. I would just go to the hardware store, grab a can of paint and head to the plumbing section to see which sizes would fit.

    In the video at 2:15 you really poured the ink onto the ground? Killing everything, including your water??? Sorry bro, this is simply unacceptable...

    The idea is very good bud here in Puerto Rico we use standard inch measures what zice I use in Inches? Thanks and God bless.

    Oh no, I should have checked all the paint cans more closely in my dad's shop after he died! He may have stashed zillions of dollars in one of them.

    This is an excellent way to put an old paint can to use! Well done.
