Replacing MBr Exhaust Fan

The family was up in Lakeport for only a short time this year, thus no major projects. I had a list of things that needed to be done like replace the upstairs bathroom tile, but no such luck. The exhaust fan was dying out and small spots of mold were showing up on the walls after a couple of showers. I couple of internet searches later I find out that the company that makes these fans are no longer in business, and finding a replacement motor would be next to impossible. So like fix it guy in me goes to my neighborhood home depot to find a reasonably priced fan with high CFMs. One thing I have to take into account in our home is the walls are made up of drywall then plaster then compound. Removing the existing fan was no easy feat. Had to rely on metal shears to remove the ductwork, to find out that the ductwork was rectangular and not the required 4" diameter circular duct. I canabalized 8 inches of the dryer hose and some flashing I had lying around and made my own adapter. Mudding the fix took some time since I wanted to make it look like that it was never replaced. after multiple layers of compound and sanding, a nice paint jog did the trick and it looks original, and the humidity in the bathroom is readily removed.
