Amount of Liquid/Flavor in 1/3rd Keg Thumper?

[Shine_Dad]

Afternoon!

I tried doing some basic searching so I apologize if this is the 12th-teen time this has been asked:

I purchased the Olympic Distillers Thumper/Double kit to clamp on to my 1/3rd keg ( 5 gallon beer keg )

First question: Am I the only person that can't get into contact with this company? We purchased this about... 2 weeks ago? The website says 2-3 weeks shipping time, but they haven't ever responded to an email Or answered my trying to call them on the phone. I'm not trying to be impatient, I've just been trying to confirm they received my order and are working on it and I can't get ahold of anyone.

Second question: With a 5 gallon capacity on that thumper, how much 'flavor/spirit' do you want to run thru that? I hear you only want the steam to run thru a few inches of stuff in the bottom of a thumper, but I don't know how to gauge that. Would I be safe to run a gallon of flavor/spirit liquid in that 5 gallon thumper or is that still too much? A half gallon?

I was thinking of adding some cinnamon and vanilla to a cheap $20 bottle of whiskey for flavor to run 'basic @$$ beginners sugar/corn' uncle jesse mash recipe thru and wanted some feedback on that please?

Also: I was NOT planning to run any heat thru my thumper... from the 15 gallon keg still to the thumper then to the condenser... this should be okay? I'm trying to setup my first still as 'old school' as I can in regards to a classic still with a thumper and a coiled condenser. ( Wish I could afford an all copper setup, but thats not in the budget this year. )

Thanks everyone !!
