I am building a steam powered pencil sharpener. The pencil sharpener looks like a lathe with the standard two roll Boston sharpener in the head stock. The carriage is the part that holds the pencil with two grabbers. when the unit is activated the carrage moves forward with a half nut the in gages with the lead screw. when the pencil is sharpened and reaches a certain point the half nut is disengaged and the carriage is free to fly back. THIS IS INTOLERABLE. I have determined that a fly ball break is needed to controll the backwards motion. Do you think that the rack turning the fly ball will be able to make enough rotary motion on the fly balls to force the break, a pencil eraser down on the way, smooth steel, and slow the carriage down. Also will the inertia that it take to spin the fly balls also slow it down?
The more complex the idea the better.
THIS WILL NOT BE A SIMPLE SHARPENER

i thought I could show my plan of the fly ball break. It is in mastercam 7 . rats it didn't show. It was a great idea.
 
The reason I am making a steam powered pencil sharpener is that I have not arrieved at this century. If I copy the image into controll print screen I think I can deposit the image into a photo program, what ever that is, by hitting controll V. If this is correct then I am not sure what photo programe I use. HELP.

maybe my gibbs 2004 will?
