Yes, we can mark this down as another use for duct tape!
Before we go any further, I need to address some safety concerns. You need to be very comfortable with fire, and have an environment where you can use open flame. Sandblasters are very messy and you need to be prepared. Also, a well grounded knowledge of woodworking is not necessary, but will come in handy. I will try to fill in any gaps in how to work with the wood where I think it is unique to this project.
Materials you will need:
Hardwood boards glued into panel (size is up to you, but you should have it rather thick). I chose 2" thick rough cut hard maple. It will work better if you use a closed grained wood (no open pores).
Metallic tape, usually used in automotive applications
Sandblaster and relevant equipment i.e. mask, gloves, sand
MAPP gas torch
Small butane torch
Xylene or other solvent
Scotchbrite pads/steel wool 0000
