Step #1: Unsealed Glove BoxPrevNext
- The most basic kind of glove box is just a clear container with holes in the side that you can reach through with gloved hands. This design is suitable for containing large particles that quickly settle to the bottom of the box such as wood chips or metal shavings.
- To make this, you will need a pair of gloves and a clear plastic storage tub. Try to find a tub that is at least mostly transparent. You need to be able to clearly see what you are doing when you are working in the glove box. Start by deciding where the arm ports will be located. You want them to be spaced out enough so that your arms will be in a comfortable position while working. Trace a 4 inch diameter circle for each arm port. Then cut out each circle with a knife or rotary tool.
Step #2: Seal the Arm Ports with Pipe and SealantPrevNext
- If you want to keep fine particles or chemical fumes contained, then you need to seal the openings on the glove box. The first step in doing this is to seal the arm ports. To do this you will need a few additional materials. To make the arm ports, you will need two pieces of 4 inch diameter PCV pipe that are each 2-3 inches long. To seal the edges of the pipe, you will need a tube of sealant. The type of sealant that you should use will depend on how you will be using the glove box but for most applications, regular silicone caulking is fine. For the gloves, I recommend using elbow length waterproof gloves. To attach the gloves to the PVC pipe you can use hose clamps, zip ties, or even strong rubber bands.
- Begin by inserting the PVC pipe into the cut holes. You may need to widen the holes a little if they don't fit. Position the pipes so that there is about 1/2 inch of pipe sticking out of the side of the box. Then apply the sealant all around the pipe on both sides of the wall and let it dry overnight. Then fit the gloves over the PVC pipe inside the box. Be sure to mount the right glove on the right side and the left glove on the left side with the palms down. Slide your hands into the gloves to verify that they are in a good working position. Lastly secure the gloves in place with hose clamps, zip ties or strong rubber bands.
- Sealed arm ports like these are much better at keeping fine particles, dust, and powder contained within the box. This feature makes a glove box well suited for applications that involve grinding or cutting with a rotary tool since these tasks often kick up a lot of fine particles that can be hazardous to breathe.
Step #4: Create Negative Pressure in the Chamber with a Ventilation FanPrevNext
- Another way to ensure that no gases in the chamber escape is to add a ventilation fan. The fan draws air out of the glove box so that the pressure inside is slightly lower than the pressure outside. This means that if there are any gaps, air will always move from the surroundings into the box and not out of the box. You can then set up the vent fan and hose to blow the air outside.
- To add this feature, you will need an air hose and some kind of fan. For a low level of suction you could use a small fan such as a computer cooling fan. For greater suction, you could hook up your vacuum or shop vac. Start by cutting a hole in the back side of the glove box (opposite the gloves) that is the same size as your air hose. Then insert the hose through the hole. If you want the ventilation fan to be removable, you can apply weather stripping around the hose to help make a better temporary seal. If you want to permanently attach the air hose, you can apply sealant around the edges.
