An assembly workbench often is used by workers and hobbyists to put things together, in large part because it is meant to make the work easier and more organized. The size of the assembly workbench often is important to consider when buying, especially if you will be using large parts or if more than one person will be using the bench at the same time. Most workbenches have shelving and cubby holes to store nuts, bolts and other small parts, and the number of shelves may impact organization. Workbenches normally have a top, though the thickness may vary by brand or style; if you are drilling or doing other activities that may make the top shake, then the thickness may be important. Some workbenches come equipped with a light source at the top, which can help in otherwise dark areas.
A common size for assembly workbench units is one intended to accommodate one person in minimal space, which may be good enough for your needs. If you are working with large parts or someone else needs to work on the bench at the same time, then getting a bigger-than-average bench may be necessary. To facilitate two people working at once, some such benches have a top on both sides, which may be useful.
When you are working at an assembly workbench, you often are likely to need small parts and tools while assembling a larger item. To help organize these parts, most workbenches have one or two shelves on which you can store small bins. If you have a large number of parts, then getting a workbench with a lot of shelving space could help keep you organized.
The area where most of the work will be done on an assembly workbench is known as the top, and the thickness of this area usually differs from bench to bench. If you primarily will be doing activities that do not cause a lot of impact to the top, such as tightening or screwing, then the general top thickness should be adequate. Drilling and other highly impacting activities may require a thicker top so you do not shake the bench too much.
Assembly workbench units typically do not include a light source, such as a lamp at the top of the bench. At the same time, this can be a useful addition if the workbench is being used in a dark area. This may add to the cost, and you periodically will have to change the light bulb, but it can be helpful enough to warrant the extra money spent.
