Long time reader first time poster i have been inspired by Hatch's pneumatic controls to build a Pneumatic sizer powered by a plc controller. I 1st had a semi automatic machine i built off of a lee press with a bullet shuttle that was still manually operated from the stroke of the handle that dropped the bullet into the die for me on the upstroke. via my mr bullet feeder i converted to drop nose 1st but im getting lazy and really didnt like pulling the handle 1000+ times every time i ran a batch. So i built this pneumatic powered plc controlled bullet sizer. here is the 1st version before i decided to upgrade the cylinder due to not having enough force to size the bullet on the 1st pass. Currently im using a drum function in the plc to run the machine until i figure out how to program and add some smarts to the machine like position and i plan on adding an optical counter to it to not only count but to also know wether a bullet actually dropped or not and rerun the ram without feeding a new bullet. ill post a video tonight of the machine in action and some updated photos aswell. Im also currently working on automating a ballisticast mark X aswell off of the plc using pneumatics.
