Diy Vacuum Pump

To make a simple DIY vacuum pump, you will need:

• A syringe
• A tube
• A one-way valve (optional)

Instructions:

1. Cut the tube to the desired length.
2. Attach the one-way valve to the end of the tube (if using).
3. Attach the other end of the tube to the syringe.
4. To create a vacuum, pull the plunger on the syringe.

This type of vacuum pump is not very powerful, but it can be used for simple tasks such as degassing silicone or epoxy resin, or vacuum sealing food.

Here is another simple DIY vacuum pump that you can make:

Materials:

• A bike pump
• A jar with a lid
• A one-way valve (optional)

Instructions:

1. Drill a hole in the lid of the jar.
2. Insert the one-way valve into the hole (if using).
3. Attach the bike pump to the one-way valve (or directly to the hole in the lid, if not using a valve).
4. To create a vacuum, pump the bike pump.

This type of vacuum pump is more powerful than the syringe vacuum pump, but it is also more noisy. It can be used for more demanding tasks, such as degassing larger quantities of resin or vacuum sealing food for storage.

Be sure to wear safety glasses when using any type of vacuum pump, as there is a risk of flying debris if the pump fails.
