@MGL I am looking to start with equipment that the farmer already has on hand. He purchased a 26 gallon distilling milk can and the plan is to start very small and give the farm a product they can sell at their farm stand to generate a little revenue.
@foreshot Thanks for the info, I was thinking of the copper onion or helmet to increase the amount of copper surface area since he is working with apples primarily.
The plan is to gain some experience and see if there is interest in his product, so anything visually appealing that I can do to help generate interest should help, as you said it is probably more for marketing purposes.
I will continue looking, I have seen some products from Alibaba but I am not sure I want to risk buying from there.
