equipment wise you have it covered.

generally speaking, these are the goods ones in that lot. Use the 50mm one for enlarging 35mm fil, the 80mm for MF. You can use the 80 for 35mm but the projected image size will be smaller for the same enlarger head height. This can come in handy when making smaller prints. You won't be able to use the 50mm for MF film as it won't cover the whole negative.

start with this with your 35mm film, check underneath how much liquid it uses probably 300ml
Quote: Secondly I want to develop 35mm black and white film, what chemicals do I need to get in order to do this, also how much of various chemicals will I need? Like on average if I wanted to develop a single roll of film how much of each chemical component would I need to do it?
for film you need
1. Film Developer
2. Stop bath / water
3. Rapid Fixer
for prints you need
1. Print developer
2. Stop bath (indicator stop bath is best, it changes colour once it's worn out)
3. Rapid fixer
Film and Paper developers can be powders or liquids. Powders you mix up the whole packet into a stock solution and dilute that into working solution. Liquids you dilute only the amount you need from the concentrate to working solution. If you use a powder (eg D76/Xtol) then store the stock in smallish bottles and they will last 6mth to a year. My current Xtol is over a year old and still working (not much developing been happening in my house!). All the dilution ratios and development times are on the packets, or find find the Massive Development Chart webpage. Generally, you use film developer 'one-shot'. You mix up some working solution, use it and discard it. To start, I'd recommend a liquid concentrate. Get whatever's available, HC110 is a good one to start with.
For film, a couple of rinses in water is fine or you can use a stop bath. Stop bath can be reused and the easy to use ones come as what's called indicator stop bath. They change colour once they wear out.
Film and Paper fixers can be the same, but keep seperate working solutions for eash as they are usually different dilutions and you don't want any contaminats from paper getting near your film. Film fixer can be reused for a set number of films before discarding. You can test the leader to make sure it good but I keep track of how many films I've used and discard before it's due. Paper fixer is similar but keeping track of how much you've processed it the easiest way of knowing when to replace. Paper developer can be reused but it goes off quickly. I keep it if I know I'll be back in the darkroom in a day or so, otherwise I discard it.
Quote: Thirdly, anyone know why the previous owner would have had so many 50mm enlarger lenses?
Probably as said above, got better ones over the years and never got rid of the old ones. Look in my cupboard and you's see the same thing
Quote: Finally, anyone have any sage wisdom they want to impart upon me, Im all ears. Especially if you have used any of this equipment specifically and have any tips or tricks you want to share.
get on Ilford's website (Harmon Technology) website, there's lots of info to get you started. Sign up to APUG and read...
