Do you need access for any reason?
If your husband can get the hole cut with precision, great. If not, the plexi extensions can be ordered for most any machine. If that's the route you are going, wait to make the framework to hold the machine and to cut the hole, til after you have the plexi, so that all will be flush as well as the distance from the edge works with the plexi.
Another consideration ... allow for space to feed your electrical and foot pedal cords thru the hole you make in the table, so they do not run over the table top.
