Home grown turntable platform/base?

I picked up a used Pro-Ject Debut Carbon turntable for the family room. We are not big into vinyl, mostly listen to digital, but my 16yo daughter has shown an interest in getting some records. I’m getting excited about her interest in vinyl and audio. What is a good platform material to use? Wood? Granite? Should I add sorbothane and/or spikes underneath? I’m not looking to spend a lot but feel I should have some decent isolation for it. The turntable currently sits on a hollow shelf. It’s where it has to be so I need to make this work.

Thanks for any input.

A sheet of 3/4"/19mm 13-ply Baltic Birch plywood (it is available in both 4’ x 6’ and 5’ x 5’ sheets) will cost you only $50 or so. Cut two pieces to size and glue them together. MUCH stiffer that the twice-as-thick 3" thick piece of maple, and more non-resonant. While some people like the sonic signature of Maple, remember, it is stiffness and a lack of a sonic signature we want in a support platform, not a pleasing coloration. IMO, of course.

I’m setting up a turntable in another room and am going to get another block. How important is the thickness and wood type given my choices at the same basic price point? I can get a 1.5"-1.75" thick piece of end cut walnut for the same as a 3" end cut piece of maple. I’ll be putting Herbie’s grungebuster Dots underneath.

Thanks.

As maple and walnut are the same density, the thicker maple is better value and at twice the thickness, more effective at damping etc.
