   Thanks for the detailed recipe, is it easy to find the chemicals?

   @charliedontsurf Yes i need to include the bleach recipe but kodak 's recipe is online. Cd3 obviously is a bit rarer but e6 and ra4 still use cd3 as does ecn2. Potassium ium ferrocyanide in the bleach is new from b&w. Then i just used f5 hardening fix recipe. Dead easy 85 degrees give it take. I like that it has trisodium phosphate {tsp} got that from the hardware store. Biggest mistake I made was i kept the particles in developer. I ended up with massive deposits all over the film. Both sides. Took a chance and cleaned the whole thing off. Then i filters all my chems. Never really had that with b&w before. But I'll filter forever now. Excited to do my second roll. As soon as i do all the stuff I'm supposed to be doing. :)

   @charliedontsurf ok here is the formula as borrowed from Francis Miniter and amended.

   C-22 yes you can still develop it on color.

   FORMULAE

   Developer (final pH 10.5 to 10.6)
   Benzyl Alcohol 8.5 ml
   Sodium Metaborate (Kodalk) 35.0 g
   Trisodium Phosphate, crystalline 25.0 g
   Sodium Sulfite, anhydrous 2.5 g
   Potassium Bromide 1.5 g
   Potassium Iodide 0.006 g
   CD3 7.8 g
   Water to make 1000 ml.

   CD3 is available from Artcraft Chemicals, among other places.

   Stop Bath (final pH of 4.3 to 4.7) (I combined hardening and fix as below)
   Glacial Acetic Acid 20.0 ml
   Sodium Sulfite, anhydrous 10.0 g
   Water to make 1000 ml

   Xxxxxxxxxx
   ( i substituted a hardening stop bath and left out the formalin
   Hardener (final pH of 10.4 to 10.8)
   Formalin (35-40% solution) 20.0 ml
   Sodium Carbonate, anhydrous 10.0 g
   Water to make 1000 ml.)

   Note: Formalin is hard to dissolve and requires extended heating to get even an
   18% solution. Purchase of formaldehyde solution and recomputation of required
   amount is recommended.
   Xxxxxxxxxx

   Hardening stop bath, however, is made by mixing up the following:
   Water (30-45 degrees Celsius) 500ml
   Chromium alum 15g. (i used potassium alum)
   Acetic Acid (28%) 14ml
   Cold water to 1 liter

   Bleach (pH 6.6 to 7.0) NOTE: E3/E4 Bleach may be substituted and acts faster
   Potassium Nitrate, crystalline 25.0 g
   Potassium Ferricyanide 20.0 g
   Potassium Bromide 8.0 g
   Boric Acid 5.0 g
   Borax, crystalline 1.0 g
   Water to make 1000 ml

   Fixer (pH 4.4 to 4.6)
   Ammonium Thiosulfate, crystalline 120 g
   Potassium Metabisulfite 20 g
   Water to make 1000 ml

   Keeping Time:
   Developer with CD3 two weeks
   Developer w/o CD3 6 months

   PROCESS

   Color Developer 14 min. @ 75.0 F +/- 0.5 degrees
   (optional 20 sec. rinse on way to stop bath)
   Stop Bath 4 min @ 68 - 75 F
   Hardener 4 min @ 68 - 75 F
   Normal Lighting may be resumed.
   Wash 4 min @ 68 - 75 F
   Fixer 8 min @ 68 - 75 F
   Final Wash 8 min @ 68 - 75 F

   Working Capacities

   Developer, Stop Bath 300 sq. in. per liter
   Hardener, Bleach, Fixer 600 sq. in. per liter

   Agitate first 15 seconds then 5 seconds per minute
   Contrast is varied by raising or lowering KBr in developer.
   If developed separately and sequentially, subsequent roll should get additional
   30 seconds each.

   @mike1allison wow, thanks. Like most things that are new to me it sounds daunting, I don't know if I would ever have the willpower to go through with it myself but very good luck to you, its cool watching your adventures unfold! Bravo!

   @charliedontsurf you just have to give yourself permission to fail.
