good tip with the contact cement, epoxies dry hard and will crack tearing the next layer of felt off.I have used 3m 5200 fast cure with good results on felt and rubber, clean both surfaces, dry,dry and then dry some more, apply to both surfaces push together peel apart to make sure you have 100% coverage[its good to have some bleed out of all edges] clamp or tape overnight and your good to go.of course if the felt is in bad shape it most likely will happen in another layer of the material soon.
