1. Sometimes, but for the smaller tubes (BAJ3-8 motors, etc) I use this one: HP30135. It's possible Jenny can order it for you. The other thing that has been discussed is making your own out of wool felt -
http://www.quiltingboard.com/vintage...l#post5534571- just make sure it's real wool, I don't know what the synthetic stuff would do. We tried 2 "felts" today, one that was sold by the meter, it was wool - smelled of burning hair when touched with flame, and the spool felts most shops sell now - it was a synthetic that melted like plastic when burned.
2. Most of them can be wiggled out with a pair of needle nose pliers covered with something soft to protect the tube. FWs are not the same, they'll just crush.
