(there was a url link here which no longer exists)comment on another thread garnered some interest. Instead of hijacking that thread, I thought I'd answer here.
I made this tank a few years ago because I could never trust myself to develop my 8x10 negs in a tray. Not having the patience to tray develop one neg at a time I would invariably scratch them. So I took a good look at my combi-plan and made something similar for 8x10.
The questions from the other thread were:
Q: Is it all metal?
A: No. It's 1/4 inch PVC sheet. It's actually the same material that my darkroom sink is made with. I drew up a schematic and had the local plastics shop cut the pieces. I assembled it myself using PVC cement.
Q: Do I develop my sheets back to back?
A: I will now!
Some other Q's and A's:
Q: how much did it cost.
A: About $30 for all the parts.
Q: How do you fill and drain?
A: Using the fill and drain spout on the side. The spout is 3/4 inch PVC pipe cemented onto the side. I open the air vent on the lid when filling and draining to avoid "glug-glugging". It takes about 15 seconds to fill and drain.
Q: How much liquid does it hold?
A: 3.5 Liters. A bit much, but less than other tanks for hangers.
Q: How do you load your film?
A: I load it onto standard Kodak hangers and insert the hangers into slots at the top of the tank.
Q: How do you agitate?
A: Like my Combi-Plan, I grab the two ends and invert once to the left and once to the right. I invert around an axis perpendicular to the plane of the film.
It's also great for stand development in daylight.
Well, hope this answers the questions. Please feel free to post more if you're curious.
