Chain Mortiser's are really 'Chain & Chisel' the chain is great to get rid of the waste but not good at cleaning up the corners hence the need for the chisel, we would use the chisel to do the square cut at the end of each mortise and then use the chisel to clean up between the two square end cuts, the chain is also good if you were doing through mortises, the thing is that they are good but you need to be doing a lot of work to justify having one, like commercially making house doors where you need to do a lot of mortises in a lot of door styles, if you are just doing a few mortises then make a jig and cut them with a router as it will cut perfect mortises and do round corners with square bottoms and do the mortise as deep as you want, do through mortises or not, there not really a hobby machine, unless you have a lot of work for it that is, and even if you do have many mortises do do then you could do them just as fast with a router if you made a very nice jig, I am very confident that I could do mortises just as quick with a router as with a Chain and Chisel Mortiser as I would make a very nice jig if I had a lot to do. So unless you are rolling in cash and you cannot think of enough ways top spend it, then make a nice jig and use a router. Routers are great as they make such a howling noise that you can't hear the phone ring. If you want to buy a machine that uses a router to do the mortise as well as a round end tennon then look at the aluminum Pantarouter made by the Forum Member called 'Samurai', you can also see it at woodgears.ca NGM
