IMHO, don't worry about the hammer felt tension. Any piano old enough and worn enough to have hammer felts popping off, it's hammers have likely long lost any significant tension (my guess). I just cram the felt in place as best I can and glue it with thick superglue. I don't notice any significant change in tone among repaired and original hammers - repaired hammers sound bad, original unpopped hammers sound bad.
