Hey all, after many years of using my 2” bok, I’m getting around to building a 2.5” bok over a 50lt keg. I’ve gone thru the LM/VM,CCM debates, and the 2” vs 3” vs 4” etc, but will stick to what I’m comfy with. My needs are modest... I just built a 2” bok for my son, and by using scoria rock instead if scrubbies, we can pull 95% at 30ml/min instead of my usual 20ml/min.
Now, for a chuckle, I’m putting a 4” perf plate under my new 2.5” column. My question is, will there be any measurable benefit? (btw, I’m using 2.5” as all the 2.5” gear is +30% over 2”, whereas 3” gear is +200% dearer.)
For the RC, I’ve simply used 3/8th inch copper tube, single wound.
I’m not sure why more don’t use 2.5”, I can’t seem to find any builds at all. Only comments from the past.
I was happy with 30ml/minute at 95% on the 2”, so it’ll be interesting to see what this one gives out.
Comments, critiques welcone ;-)
