I would have to agree with Smallpatch on the least favorites, only mine would be rear entry thimble & one piece nosecaps, the nosecap makes me real nervous. One thing I do when inletting the rear entry, besides going real slow & careful, is I use a line level to level the forestock on the bench & support, then insert a tight fitting dowel rod about 6" long into the thimble and use the line level on that as I inlet to keep it level as it goes in.
