Can someone explain what the "hypo eliminator hose" on this item actually does?

It's a hose for supplying and draining water from the tray which helps eliminate the "hypo".

Looks like it operates on the notion that the hypo laden water sinks. This has been discounted by some of the chemist posters in some of the washing threads.

That's what I thought. Thanks, Barry.

I have been reading the thread, and though I have no experience in processing prints so large, I have a suggestion. (Worth what it costs)

J,
You said you are using 8" PVC and need a tray for it. Have you thought about using the next size or two larger (10"?) and cutting it 1/3 length - wise to provide a tray? Of course you would have to somehow cap the ends, but it would seem to me to be cheaper than Stainless Steel and if nothing else provide a "prototype" for the SS trays you mentioned.

Good Luck, I'll be where you are by this Fall if my replacement bulb idea for my MVT 57 works!

I made 4 of these for doing 8x10 negs - they work great

I think I'm over this idea. I think that when I decide I need to manage 16x20 and 20x24 paper, I'll buy these two items:

3063 Drum

Dead Link Removed

p.s. if you get one with a spare cog don't insert the cog unless you want it permanently attached

With this drum, you can do a 30"x60" print - Expose it, put it in the open top. Dump 2 liters of developer in it. Roll it for a few minutes etc. I just ordered one. It will hang off my rollers 5" on each side - no problem - it is RED .... cool huh - not that I need anything more than my safelight but ... maybe it becomes its own safelight? - anyway - looks like a better way than I am doing - or at least it will help with the wash cycle - which for me sucks right now. - I think I will bore a 2" hole in the center of the lid and use that to add chems while in motion. - Of course my long - narrow trays do work good for development - either way -

With my two 20x24 inch stainless steel trays, Leedal, all I needed was that Yankee wash tray. The drums look good too.

Two trays and a wash tray. I can dig that. Dan

Instead of buying the drum you can go to any pool company an get them free , when they use backing soda or other chemicals stored in those drums. they have to dispose of it .
