At this point I am cutting the mortises from both sides with hammer & chisel – not using the 3/4” forstner bit. This is the first one.
Two done, six to go.
One thing I discovered during this experiment: the mortises on the first board that I cut using the 3/4” forstner bit were a tighter fit for some reason. The second board mortises were all done with hammer & chisel and came out a bit oversized as shown in the pictures. I was able to keep from making the last four mortises (13/14/15/16) as big as the previous four (9/10/11/12) using only hammer and chisel. So it’s a learning curve getting it just right. I guess some folks make their mortises first and then cut the tenons. Not sure that would have enabled me to make tighter joints or not. I’ll have to experiment some more.
