Building my own slot processor - am I mad?
I'm new to the APUG but have been shooting/developing/printing B&W for a few years now.
In my previous darkroom I used trays too process my prints but now I've moved house and building my new darkroom (in the loft) I was interested in finding out more about vertical slot processors.
Trouble is they are so expensive. I have to admit that I've not searched for secondhand items yet but I have started to think about how hard it would be to make my own slot processor for basic B&W printing?
As the title says, am I mad to be thinking this or has anyone else managed it and to what degree of success?
Thanks for any opinions,
Polycarbonate sheets can be bought from the places that sells window glass, screwed together with a sealant in between. Maybe a siphon to empty it. Just ideas.

Welcome to the asylum.
I was originally thinking of using glass but poly sheets are a much better idea, thanks.

Yes, depending on definition you might be mad… But, well, in that case so am I. If your initial impression is “how hard can it be?” - I definitely think that you should try to build your own vertical slot print processor.
Welcome to APUG
Anthony In recent weeks a 4 slot Nova with thermostatic control went for just over £50 on e-bay and it looked OK from the picture. OK most will go for more and certainly Nova itself or Secondhand Darkroom Supplies will charge more as is to be expected. Given the difficulties of producing one yourself, especially a heated version and the longevity of the professional models, I know which I'd opt for - even if it meant persisting with trays while I saved the money needed for purchase.
I'm using 1/4" thick black ABS. It'll be capable of 20x24" prints. The sheets are ripped. When it get's a little warmer, I'll crosscut them and glue them up.
I built one out of 1/4" acrylic bonded with an acrylic solvent and reinforced with epoxy.
Before i put the sides together, i used my table saw to cut half the 1/4" width into the side.
I think its called a daito or a rabid....I have to brush up on my This Old House for the correct terminology.
Anyway, the processor worked great until i loaned it to a friend and never saw it again.
I purchased a 4x8' sheet of acrylic online, it was about $100. IIRC, I was able to get 3 11x14 slots out of it with plenty left over.
Its a fun project to take on. My only recommendation is a very sharp table saw blade. If its not, you will chip the acrylic.
No! If you build any processor, the slot processor is probably easiest to build and judging by the price of these things it does make sense.
