Anyone Tried Wallpaper Troughs for Large Prints?

John, if you want them I have a copy of an article from the old Darkroom Photography that tells you how to make print processing drums from PVC pipe. The writer had one made from 15" PVC sewer pipe that'd do 40 by 50 prints. If you want a copy PM me with a mailing address.

Is there a reason it can't be posted here? I'm interested too.

The main problem with PVC drainage pipe is that it's ordinarily white and slightly translucent. Black ABS would be stronger and obviously opaque. Industrial pipe
suppliers stock or can acquire all kinds of things, but true irrigation suppliers might be cheaper on certain common items. Home centers won't carry pipe of large
enough diameter. Some of these plastics need to be scrubbed well before use due to residual mould release compounds etc that can affect developers.
