It's not an all day job for the Renner kit if you are not doing any modifications. The first time you do anything it takes longer but that will be the case whether it's a Steinway back action or a Renner one. Don't imagine that no modifications will be necessary if you use the one from Steinway. Modifying is often to correct the geometry of the original and that may be necessary no matter whose kit you use. A straight ahead duplication can be done in a couple of hours on either one. If you are adding a fine capstan adjust you can add another 1-2 hours. Relocating the return spring takes no extra time as you have to locate the original anyway. Figuring out whether the pivot pin is in the right place can take a little time but once you establish where to put it there is no extra time involved in putting it there. If the concern is how to charge for making a new one then Jon Page's 4-6 hours is about right depending on the extent of the modifications. That, of course, doesn't count the actual installation of the dampers themselves or regulation.

They CLAIM it is a 2 hour job, and that there shouldn't be any re-engineering. I suppose their claims are based on what is being done in the restoration center where the techs do that job on a regular basis. I've not done that job. I'd ordered a S&S back action for a B at the university, but we never got that piano in the shop before I left. But it is SUPPOSED to be made to fit as a direct replacement with a simple side to side adjustment.
