In response to a question received, another thought on making your own gaskets. 

The reason that commercially made gaskets are cut away, is to allow someone to install them without being concerned with aligning holes with holes. 

The outside diameter (OD) of the two gaskets that seals the see-through cylinder, only have to be barely small enough to fit into the depression of the top and bottom plates. This fit is made to rather close tolerances, but not difficult.

The gasket's do not need to be cut away on their inner aspect, except in the areas that require a hole, such as where the drain plug is at, a water passage is at, or where the strainer passes through. Looking at the insides of the top and bottom plates will reveal where these holes are. 

Better to make these cut outs too big, rather than too small, as long as they do not compromise the gasket's sealing ability. Ragged cuts do not matter either, as long as the gasket seals.

If having trouble keeping the gaskets in place while assembling the strainer, something like rubber cement, or a permatex product called high tack, works well to hold them in place. 

To cut the gaskets out, use, as one poster mentioned, a sharp knife. A razor blade, or scissors may also work.
