Instructions on how to make a gasket
Make sure you buy gasket material that is suitable for your job as gaskets are made in many varying materials for different application. Refer to the materials specifications to see if this material is suitable for your application.
Items you will need: scissors , sharp knife, pencil and fine-grit sandpaper
Clean the area. Use your razor blade to scrape the old gasket material from the surface. Use fine-grit sandpaper to remove any leftover material. Do this by lightly sanding the surface until it's clean.
Cut the appropriate size. If you have the old gasket, use it as a template, & using a marker trace the shape onto the material. If you do not, go to step 3
To make a paper template, hold a piece of paper material firmly in place and use a pencil's eraser to mark the new gasket for cutting. To do this, press down on the pencil eraser on all points where there is a bolthole or edge. This will leave a mark on the paper, looking as if it was pressed into the material. Now hand draw around the marks on the paper & cut it out. Use this paper gasket as your template
Cut the new gasket. Place the gasket material on a hard surface. Use your knife to cut out all bolt holes. Once this is done, you can cut all edges of the new gasket with the knife or scissors. Hold the gasket against the surface it was made for & check all boltholes match so the gasket will seal properly.
Install the new gasket. You are now ready to bolt your parts back together.
