I am new to the forum, but have been keeping bees for several years. My Dad has taught me what his dad taught him and so on. We have been using a 2 frame tangential extractor for several years. I now want to build a radial extractor. I have the food grade barrel that i want to use so i know the dimensions. My question for the moment is, can you use aluminum as the supports for the frames? I know i can make it strong enough, but this is more in the line of is it acceptable to use aluminum as a component of the extractor. Is it safe for aluminum to contact honey, are there reasons not to use aluminum rods and extrusions? These seem pretty light weight, I can weld them etc.

Just a question and i appreciate your comments, warnings, advice etc, in advance.
