I use a unicolour 4x5 drum four sheets at a time on a unicolour roller base. I find 3oz of developer and blix one shot works reliably. I rinse one minute in the drum then store in an old Yankee tank until all are finished, usually a dozen. Washing is 5 minutes in the Yankee tank.
Temperature control is by placing the 3oz of fluid in a small graduated cylinder and placing it in a larger container with hot water. I monitor the temperature closely and pull when it reaches 92F. By the time I pre-rinse the small quantity is at 90F.
I stabilize in a tray at 25C.
Oh yeah, I use the unicolour dry chemical kit from Freestyle.
