[pianotech] Thubby Chipboard, was: Flagpoling

Nothing funny about my post at all. Okey-dokey, then let's take this a step further. What exactly is "chipboard"? Exactly how does it differ from MDF?

Caused by extremely tight tuning pins and perhaps the wrong type of steel, in combo. (It also had a chipboard cabinet core, which made it sound "thubby". )
