3" Piston Ring Compressor_Bright

My students needed a custom-made piston ring compressor.  They were practicing assembling their small engines in class, but trying to clamp the parts together created issues where the students would cut their hands as they were pinched.  I created this funnel-like tool where they could stack the parts into the funnel, then use a light mallet to pat-pat-pat the parts into place.  Works VERY well!
