Aluminum in cld plinth

It might be worth a try. How do you plan on implementing it into your design? All aluminium or sandwich together with another material?

I personally would use 6061 or 7075. I would use 1" thick and CNC it. I have access to the machines so it is a bit easier for me. With that said, if you are looking to do this yourself you can.

I am planning layers of 3/4" birch plywood and mdf, and am wondering if sandwiching some aluminum would be of any benefit, as I have the 1/8th sheet for free.

I dont have the cnc machines to cut this but I an sure I have the connections. I would want to know it is worth it, if I were to call those favors. I can cut the thin sheet myself with stuff I own.
As always thanks for your ideas and knowledge!

I am hardly an expert, actually very far from it.
Some TT designs use aluminium as a plinth material.
However sandwich is kind of new to me and might or might not be beneficial. It is hard to tell, at least from my point of view. I am working right now on the plinth for my Lenco. Materials used are premium MDF 3/4 inch and Baltic Plywood which is better then Birch in my opinion (13 layers in 1 sheet ). This plinth is my second one, so my experience is very limited. My first one is made from Bamboo BB, walnut for arm board and Mahogany motor stand.
I also didn't find a lot of support but took a chance and it worked just great. Bamboo BB is about 10 times harder then maple BB and it sounds GOOD (I don't want to put to much sugar in your tea - but it sounds GREAT ). What I'm trying to say try it - my advice, make it heavy (40-60 pounds ). You can also incorporate a dedicated TT stand & platform for even better performance.
I would only recommend that you use top & bottom layers out of Ply. or MDF + separate arm board(s).
Keep us informed on the progress and your final design.
Good luck on your project.
