Where are the French Unions when you need them?

Day 3 of the 6 day shift cycle. Shift midday till 8:00 pm
Press - PZ45
Tiles made: Rives Plats Rouge Veilli 4200
Dry Tiles unstacked: Demi Postel Rouge, Rives Plats Rouge Veilli

The Rives Plats are normally easy to make, they are small and light and come direct from the mouleuse. You grab the tile, put on a chassi, press the pedal to advance the chassis, grab the next tile.
Except today we couldn't adjust the chain that drives the chassis correctly and the claie of 8 chassis would shoot off to the ascenseur when you only had 4 tiles on. So the procedure was: put 6 tiles on without advancing the chassis. Press the pedal to send the claie off. Grab 2 tiles while the claie goes past and put the 2 tiles on the chassis. Continue to kick the pedal while handling tiles in both hands to get the next claie (which is 4 tiles behind) to come within reach. Lay tiles and kick the pedal until the claie is in its ready to shoot off position.
Madness. Plus we were short on personell again so I didn't get a break until 4:30. Four and a half hours graft without a break.
