As I posted later in the thread, the HF 20 ton press needs a 1.5" adapter so excuse the typo in the thread title.
I'm making press adapters for removing AK barrel pins. The 1" adapter fits the ram on the Harbor Freight 12 ton presses, the 1.5" adapter fits the 20 ton press. Each adapter comes with a long and a short hardened steel pin, extra pins are 5 pins for $1. Please specify whether you want extra long pins, short pins, or a combination of both. The adapters are $25 shipped priority mail to anywhere in the US.
