I've done many pianos like this. Mostly they've not been Baldwins, however I 
just finished my 4th Baldwin in 4 months. I figure about 4-5 hours total. I 
usually take around 1-2 hours to loosen the tension, glue, clamp and bolt the 
thing back together. The second day is typically something from 2-3 hours to 
bring back the tension, tighten up the coils, and properly space the strings. The 
last one I did was a spinet with the veneer on the top. Since the veneer was 
not cooperative in coming off, I found a sheet of brown name-board felt to 
cover the top. Saved a lot of time messing around with matching veneer!

Good luck!!
