This is a drawing of the new gear plate and of its related parts. NOTE some dimensions may vary by machine manufacture! Depending on the quality of your "A" shaft mount, you may have to modify it or make a new one. If you make a new one, I recommend adding a ball bearing to the "A" shaft. The bottom plate mounting spacer will have to be modified too. The Mount Cap may be different depending on machine hardware and "A" gear mount. The spacer with 0.242 dia. middle hole 0.155 dim. may vary depending on machine but should be at least 0.120" for good operation with T-nuts.(The 0.155 dim. is required for multi-gear addition) This is a nice project but you do need to do your home work.

This is a drawing of my "A" shaft ball bearing modification. The "A" shaft mount may be different for most machine manufactures so I am not sure this will work. Adding a bronze bearing would be an improvement though.
