Just finished up a new Keg still, pretty standard stuff 24" tall column thats 2" in diameter, goes down to a 900mm liebig(3/4" jacket with 1/2" vapor tube) etc etc nothing fancy.
anyway I happen to have an extra half barrel keg and a 1/6 barrel stilling around and enough tubing, fittings, TCs etc to set them both up as thump kegs.
here is my question
would there be an issue with the second thumper being a smaller 1/6 keg with the bigger 15.5gal thumper keg in line before it? my brains tells me it should be fine, but dang ol brains also make me check here on HD before I go thru with building the whole setup as there are some nuances to this hobby that arent always that obvious. IIRC a 1/6 barrel is like 5.16 gallons or something which would make it about adequate following the minimum thumper size of 1/3 the boiler volume.
LMK what you sweet guys and gals think about this, so i can get on with some madstillin
thanks in advance

Ideally, the "rule of thumb" for a Thumper says it should be sized around 1/3 to 1/2 the capacity of your boiler. A Thumper sized that small, (1/6th,) may not be your best option. Although I mainly run my 4" Plated Reflux Column for most of my stilling, when I do set-up my equipment to run in "Pot Still" mode with my 3" Lyne Arm and Liebig condenser, I have a 26 gal boiler that I can use along with my 13 gallon boiler as a Thumper, and if I want to use my 13 gal boiler, then I can hook it up to my 8 gal. pot as a Thumper. (All modular components.) Just my 2 cents.
Here's my 13 gal boiler with my 8 gal. Thumper.

excellent thank you much for the advice. beautiful setup by the way. im going to upgrade myself to a 28gal fusti tank at some point. i also have nearly everything i need to build a reflux column so ill be working on that slowly but steadily while i get back in my groove of stillin. the last run i did was august of 2016. bad breakup and the ex has my old 15 gallon copper pot, in hell, where she lives.

I do not understand about the rule of thumb for the size of thumpers. I use a boiler of 10 L as a thumper for another boiler of 10 L.
I have seen diagrams of double thumpers for distilling rum. These are both about half the size of the original boiler, at least in the picture.
