A bench grinder is a great multi-purpose tool that is a workhorse in many shops and garages. A bench grinder can be used in a variety of applications, and for a variety of purposes. It is important for a bench grinder to be secured firmly to a solid and stable surface for both safety as well as quality reasons. Due to the nature of the bench grinder, this is one of the more dangerous tools that you can use in a garage, and as such it is important that it is used in a secure location that is not subject to disturbances. A workbench is an ideal location for your grinder, and can be made of scrap wood in the course of an afternoon. While the grinder does not need to be out and available all the time, many prefer it to be so, and it is very possible to make a bench that will accommodate different preferences. You will find information here on how to build the ideal workbench for your bench grinder.
Step 1 - Measure and Cut
First, measure the height that you want your bench to be. Measure from the ground or floor to the top of the table. This may vary depending on the height of the person that will be using it. An ideal height is about waist level, so that you don't have to stoop to use it, but are not looking up at it either. Cut the 4x4s to this height. These will be the corner posts for the table. Next, Determine the width and length of the table desired, and cut the four two by fours for each measurement. Finally, measure the length and width that the top of the table will need to be, and cut the plywood to these specifications.
Step 2 - Assemble
Assemble the table by attaching 2x4s to the top of the 4x4s as well as the bottom. The ones on the top should be even or just slightly lower than the top of the corner posts. The bottom 2x4s should be attached about 1 to 1-1/2 feet from the bottom of the corner posts. Finally, attach the plywood top by screwing it in to the corner posts, with a couple of extra screws into the 2x4 rails.
Step 3 - Install Bench Grinder
One thing to keep in mind in using a bench grinder is that there is a lot of heat generated by the grinding wheel, and it may be worthwhile to put a flame resistant overlay over the plywood, such as tin sheeting. It is not imperative, but if you do not, keep an eye on any sparks thrown or hot material on the wood when working with it. Place the bench grinder on the table, and position to the best placement. Using a pencil, trace the shape of the grinder to mark the positioning. Most grinders have holes in the base to secure it to a surface. Mark these holes, drill them out of the wood, and attach the grinder with the bolts.
