[Lab] Laser machine fumes

[bentfork at gmail.com]

I've had good luck sourcing birch plywood from lee valley tools.

I've hear rumours that Rona has it, however I have never seen it in stock
myself.

but I've never tried finding it in store.

Also I'd recommend trying mdf, if it is very thin it lases very well
