From and earlier post.....I was looking for a way to turn of my fan while loading wood and have it come back on automatically.

If you don't find a "proper" one, it would be easy to make. A wind up bathroom fan timer (I just bought a new one on fleabay for $15) a NC relay with 120v coil, and a 4x4 electrical box. Wire the relay inline to the blower so that when the timer is turned to XX minutes, that activates the NC relay to be "open" thereby turning the fan off until the timer runs out. Timer and relay mounted in the 4x4 box of course...

So I followed his suggestion and here she is being tested. Relay was about $8 and is behind the solid plate.

Ideas are great, but it's the person who puts an idea into practice that gets my highest respect.
