Questions, questions, questions...
This is an interesting question Barb. The same question, in reverse, is most probably asked by anyone with a router table while contemplating obtaining an overhead system. Here's a short, less than complete answer. ---
At first thought, there is one thing a woodworker can do on an overhead router that can't be done on an under table one. That is pin routing. This way, many duplicates can be made from one template and even some sculpting of relief plaques and relief signs. Table routers can be used to make duplicates by using routing templates or flush bits with a top bearing. Duplicates can also be made with hand held routers. It just seems that pin routing is a bit easier.
The first routers for home craftsmen were hand held. Soon tables came into vogue. Many of us have used router tables and are used to them and their quirks. There is a wide variety of fences and jigs that allow a multitude of operations. We adapted our skills and our brains to think of the table router.
Box joints are one reason to have a router table as well as an OR. There are probably several more. With an overhead router, since there are not as many in use, woodworking magazines have not devoted space to their use an possible jigs. I would find it prohibitive to make a jig for an overhead router that would allow making routed box joints on the ends of a board of any apreciable length. However, box joints are easily cut on a table router with a simple jig. (with Shopsmith's OPR in horizontal mode box joints are as easy as with under table router)
Now let me digress to my not totally unbiased thoughts of - "Is there a reason to keep my router table, now that I have an OPR?" As of now I have only thought of one reason to keep my router table. The table is huge! 3' by 4' if needed and there is an infeed side (workbench) that is more than 8'. Outfeed can be through the door and is unlimited. Other than that, there is no operation that I think can only be done on the table, and not also done on the new OPR. The Key is the horizontal mode.
