Method of Compressing Metal by liquid Nitrogen Check it out!

Method of compressing metal by liquid nitrogen. Liquid nitrogen is unbelievably useful! When metal is placed into a bath of liquid nitrogen it shrinks in size. This is commonly used in the engineering world to put metal components into positions they otherwise wouldn't fit at room temperature. In this video we fit a bush into a bore without any Special tooling such as a large press. This procedure can be done anywhere from in a workshop to out in the field, with little effort and a lot of fun!
Installing a metal bushing sleeve with liquid nitrogen can be a complex process and should only be attempted by experienced professionals with the necessary equipment and safety precautions. Here are the general steps that are typically involved:
1. Obtain the necessary equipment: You will need a metal bushing sleeve, liquid nitrogen, safety gloves, goggles, and a suitable installation tool.
2. Prepare the metal bushing sleeve: Clean and dry the inside and outside of the metal bushing sleeve to ensure that there is no dirt, debris, or moisture that could interfere with the installation process.
2. Chill the metal bushing sleeve: Place the metal bushing sleeve in a container of liquid nitrogen for several minutes to chill it to a very low temperature.
3. Install the metal bushing sleeve: Quickly remove the metal bushing sleeve from the liquid nitrogen using safety gloves and goggles, and insert it into the installation tool. The low temperature of the metal bushing sleeve should help it to shrink slightly, making it easier to fit into the installation tool.
4. Allow the metal bushing sleeve to warm up: After the metal bushing sleeve has been installed, allow it to warm up to room temperature before using it. This will help to ensure that the metal bushing sleeve has expanded back to its original size and is securely in place.
5. It is important to note that liquid nitrogen can be extremely dangerous and should be handled with great care. Always wear appropriate safety equipment and work in a well-ventilated area to avoid inhaling any fumes. If you are unsure about any part of the installation process, consult a professional who has experience with installing metal bushing sleeves using liquid nitrogen.
