Caliburn 1/2 in brass ram tip

thingiverse

Superglues securely attaches to K&S 1/2 inch brass and holds in place a standard Caliburn ram/Danco #7 o-ring tightly sealed to .527 ID aluminum. Use it to craft your own caliburn ram rod, or shape some brass into any stock breech to create an effortless pusher breech. This example demonstrates a retractable platform. May print slightly small, either scale up slightly or apply a layer of super glue in the o-ring groove to fit a good breech seal perfectly. Batches of .527 aluminum will vary in ID measurements. If using on a caliburn/tc platform, you may want to cut some anti-vacuum loading slits on the tip of the seal like Slug's aluminum ram has, Retal platforms do not form any vacuum instead. Unfortunately, I don't have a model variant for this, as it was created on my school's copy of solidworks, which I lack access to my home machine.
