I have a really nice Mason & Hamlin console. The hammers were delaminated/ exploded so I put in a new set of Abels. Several hammer butt return springs were broken, so I replaced them all. They are heavier springs than original. Now I have a serious hard escapement. Mmmm!
I am wondering if it really has a deformation of the hammer butt buckskin, or too tight return springs, or something else.
Any ideas welcome. The piano is worth the trouble.

It is probably the springs. They will weaken a bit with use, or you can bend them back a bit.

You might be surprised. Some customers like the heavier "touch"

If the new hammers are heavier this would account for what you are feeling because of the increase in inertia and friction. It is most likely that the Abel hammers are heavier than the Aeolien M&H.
The springs are intended to have the tension adjusted after installation. They are made too strong because weakening is easier than strengthening.

Another thing to check is the return-spring groves in the hammer butt. The old wire may have been thinner and the new ends may be digging in a bit.

Springs working better with lessening the tension, BUT!
Help! It is not buckskin on the hammer buts, but a bicolor material that is grey fuzz on the bottom and dark brown on the top. It is not like Baldwin's corfam. It has compressed where the jack strikes and rubs, turned shiny and really Sticky! Aweful stuff. What is this?
I ordered a supply of Ecsaine, and am planning to replace it all.
Any ideas?
