Spoilboard support surface?

[Ajcoholic]

There is one other product that I might try some day... I use this in my cabinets for thick tops, or floating shelves, or other uses where you want a stiff but reasonably light material.

It is two layers of 1/4" MDF separated by a honeycomb paper. Similar to what is found inside of a door.

The material comes in various thicknesses. I have some 1 1/2 and 2" in my shop.

This is the product..

Would be neat to try it, but I dont have reason to right now, and it isnt cheap at about $100/ 4x8 sheet

Look into making a torsion box. They are very strong and light.
A cheap hollow core door is a torsion box thin ply with a corrugated cardboard interior.
