I am trying to do a similar thing but for a Frankford Arsenal (FA) X10. Currently I am just using the normal 3D printed feeding die but the window approach would be great given how FA designed the stations for this press.
But my first challenge is to print out an "adapter" to attach/connect the 3D Printed Standard Bullet Collator to the X10 stand bar where the factory Case Collator is already attached/connected. Do you know if anyone already did this and has a stl file available? Thank you.
