Unless you are going to turn several stocks, even better if you turn the same one multiple times, it is easier and cheaper to send it out. That machine has the minor problem of vibration to overcome. The less rigid the machine the more slop in the copy. That set up is OK for a 90% finished job. Not accurate enough for 95% stocks. And a 90% job leaves a lot of wood to remove.
I invested three plus grand in a duplicator and it sits unused. The learning curve for through bolt guns is not to bad but it is longer for box locks and it gets real long for sidelocks.
Set up is key and going slow, with sharp cutters is vital. I have a Baker to do of my own but have been putting it off for six months. Decent pattern is the first thing to make and then you have to get it in the machine in as solid a positions as you can get. Glue up both ends to wood blocks and then screw these into the machine fixtures. Slop and vibration are killers for accurate duplication. Plus it takes up a heck of a lot of room in the shop. My table is about three feet by five feet and it needs two feet clear around all sides to use. Lot of floor space in a shop. I will sell it in a year or two and go back to sending them out. I still have hopes of using it but know that the longer it sits unused the more it needs to go.
Three grand would copy a lot of stocks if I sent them out.
