Can X Carve do finger box joints? I make jewelry boxes out of eastern red cedar, it is a much more professional looking product if finger joints are used to assemble. yes it can be done on a jig saw or band saw, but there is the dreaded learning curve
I am sure that it can do this provided you have the correct measurements. It does seem to me that you could set up a jig on a table saw or prefabricated template or even a router bit.
I have used all 3 methods with success in the past and will probably be faster.
I have seen a few guys on here that have done it on the xcarve. They cut a hole in the waste board so the material can hang underneath. Maybe try searching boxs joints you might find something.
There is the box generator app which does finger joints. Its only problem is that the round bit can’t produce square inside cuts and so there is a bit of finishing required. However, the end mill can produce square cuts if you hang the stock over the side vertically. To see this in action watch this video.
