This will soon become your favorite method of dimpling and riveting. The actual setting of the rivet occures during the last 3/16″ of the ram travel – where the squeezer produces power. Common washers will work but do squash out and hinder repeatability. Hardened shim washers are added under the flat set in the ram for fine adjustment. Long rivet – Short flat set Short rivet – Long flat set We use the set of 8 ranging from 1/8″ to 1/2″ long. Choose the correct length of flat set to correspond to the length of rivet being squeezed. For Riveting: Use the 1/8″ long flat set or 1/8″ long cupped set in the top of the yoke.Note and use shim combinations to get desired result in each skin thickness. Note the differences in the dimple shape and in the “flat” skin around the dimple. Compare under squeezed and over squeezed dimples. Add or remove shims to adjust for various skin thicknesses. Repeat until closed dies are just tight enough to be difficult to rotate with finger pressure. For Dimpling: Insert male die in top of yoke, female die in the ram, plus a couple of thin shim washers.Always drill and deburr the appropriate sized pilot hole for the dimple die.Oil will wash out the grease and ruin leather piston. Power is developed through mechanical advantage not increased air pressure. Always disconnect air before changing dies or sets.Do practice on scrap to become familiar with this powerful tools operation. Buzz has also written up additional instructions to explain use. Squeezers do not come with instructions from the manufacturer but we do have an info sheet we include. It is manufactured for factory production use and I’m sure the operators get on the job training. The pneumatic squeezer is a terrific tool but does require some understanding of its set up.
