Lift Duct moves forward

This week we came in to see the inside of the duct had expanded with the foam used to attatch it to the deck. We had to cut off a section of fiberglass and foam to fix the problem. We began the process of mounting the shaft for the fan and mounting the pulleys on the duct. On Thursday we cut a section of the lift duct out and reglassed the parts together. we did this to decrease the height of the duct to allow for the siding to be put on.

This week was a slow week because, for a few days, we did not have a full crew. There was some vary important things that did get done though. One was the removing of extra foam so that the duct could sit at 30^o from the deck. The other was the installation of the 1×6’s. This will support the fan, so there was alot of measuring and trimming and re-measuring and some more trimming. I am going to try to add pictures over spring break.

Lift duct takes shape

We made alot of progress this week. The lift duct has been constructed using layers of fiberglass epoxied to take the shape of the duct. It is fairly rigid and we believe it is the best answer to our problems. On Thursday we wrapped the fiberglass duct in 2-inch foam to complete the shape. We arn’t quite shure how this is going to turn out due difficulties with getting the glass to properly form to the foam. We are all hoping this will work

Lift duct may eventualy get finished

The lift group might have finaly found a material that will work. After struggleing with the 1/8 in plywood for a month, we gave up on that and have moved on. Our solution was found using layers of fiberglass as the inner material to provide durability to the duct. We hope this will finaly work. Our lift fan is mostly done, it is completely epoxied and all that remains is balancing. Our lift duct may get done eventualy, but dont hold your breath

Lift progress slow, but coming along

This week the lift system has made some headway. They got the duct inner wall glassed around the circular form and are ready to begin the outer duct form. We’ve discussed how to do this and have come up with using the 2" foam like UH recommends. It should go pretty quickly. They just have to figure what length they need and then they can cut to length and begin making relief cuts to allow for bending to the right radius. They are on the right track to possibly be spraying the expandable foam this week.
