<html> <body> Hi Dale,                 Joe Goss of Mother Goose tools has a nice Aluminum , square bar, already marked.   It doubles nicely as a key leveling tool. You are right, it's a dead sure way to travel.

It requires a flat stick like the ones that come in the Renner shank boxes or something like it. With a square simply mark a multitude of lines the length of the stick.   Next with the action stack sitting on a flat clean surface we use a square to travel the shanks on the end of each section so they're dead accurate. Then clip the stick -o- lines to the end shanks with clothes pins. Now as you lift up and down the shanks that travel are easily seen moving in reference to the lines. It's a slick trick & easy to see especially for those of us with bifocal.    Prior to this we just used a square on each shank which made it tedious & eye straining.   Any residual traveling will show up as a minor movement after the hammers are hung & can be easily corrected. You can also be sure that you didn't successfully travel all the hammers going in the same direction i.e. left -right   Happy traveling     Dale     Erwins Pianos Restorations 4721 Parker Rd.
