Back in Dec. 2023 @WilliamG posted a picture (below) of his RAW with a cool empty chamber indicator. I’ve never seen them for sale anywhere so I made one today.
I had a small teflon ball from an old diaphragm pump I tore apart. I drilled an .082 diameter hole almost all the way through and then 90° to that I drilled and tapped a 10-32 hole almost all the way through for a set screw. I inserted about a 10” length of .080” diameter weed whip line into the hole and locked it in with the set screw. I took a stone to the end of the weed whip line to put a radius on it so that I didn’t have a sharp corner that could cut an O ring.
Thanks WilliamG !
