Travelling before hanging hammers is not that difficult if you place a strip of wood across the tops to aid in their return. A handy procedure to get the replaced hammers aligned is to make a story stick. I have a long thin rail to mark the string cuts for indexing the hammers. One end is notched to fit/index onto a square and the square is braced to the end of the frame or stack with masking tape. Masking tape is also run along the rail to place the marks at the string cuts because it is easier to remove the tape than to erase all the marks. Once all the hammers are rehung, travelled and burned-in the square and rail is used to get the hammers aligned to the marks. This gets the hammers in place with minimal spacing to do in the piano. It certainly get them close enough so that the wippens can be spaced to the knuckles.
