We called in on M. Chaboisson yesterday afternoon to check progress. After handshakes all round Jean-Louis showed us the stringers, which have now been routed to take the steps (marchés)* and risers (contra-marchés)*, and pointed out that the apprentice was cutting the handrail blanks. All of our steps have been shaped, (with a natty litle curve and rebate on the underside) which we would have taken photos of except the batteries in the camera went dead.
M. Chaboisson has an informal little museum in his atelier, including old doors he has made replacements for, and a collection of old tools. He also made a replica cell for the donjon in Loches, pictures of which are here and here.
p.s. Someone we know is having bacon and eggs for breakfast today.
