When I picked up the drum sander from the rental store, the associate very clearly stressed the importance of emptying out the dust bag for the sander regularly. He said failing to do so would cause the bag to explode. Since the associate made such a point of mentioning this information to me, I made sure to pass it along to Tyler. And this is where we find another example of men hearing something other than what women are saying.

Tyler interpreted my explanation of the importance of emptying the dust bags frequently as having to change them frequently. But, the problem was that the rental store only sent us home with a few dust bags. So, Tyler - being a logical engineer - deduced that this meant that he had to fill each bag up enough before changing it so that all three bags could make it through the weekend. And, that is how Tyler ended up looking like this...

And, the poor room looked like this... (Can you find the dog and the drum sander in this photo?)

Tyler adamantly claims that the bag exploded because it slipped off the drum sander rather than because it was too full. But, this discussion lead to our discovery of the miscommunication. After that, we started emptying the bags and there were no more Mount St. Helens explosions. There was one other minor explosion, but that was because Tyler bumped the bag.
