The piece with the notches does fit into the bar with the cutouts = foot rest. Thank you for letting me know it's suppose to be tight.
I've been cleaning heddles, bars and frames. The heddle still are white-ish, not shiny aluminum. but I guess I can live with that, it doesn't effect the yarn that I strung through to test them out.
So far I've clean three harnesses with 590 heddles some of the harness have more heddles than others, but I want to get through them all and then even out the numbers on each harness. I'm keeping and individual count on each harness and writing it on the bar with a white grease pencil so that I don't get confused or lose my notes.
This is as clean as I got the 15 reed, I strung some yarn through it and did a dental floss type of cleaning, I think that's about as clean as I can hope for.
