Well Ken, Hope you are enjoying your retirement. The 4216 will certainly take up some time but very rewarding for your efforts. There are (not me) a few here who are quite crafty with it and can give you some great guidance.
There is a learning curve with the jig and a problem for me is that I don't use it often enough so when I go to use it again after a period of time, it's almost like starting a new having to read the instructions etc. etc. But once you get it set up right and can throw down the manual it's a pleasure to use.
