Furnace Blower

I am working on producing a foundry. This is the box I made to muffle the sound from the motor that came from a vacuum my neighbor threw away. Actually there were two vacuums that they threw away because they got a central vac system. I fixed one, and here is the other. I had to make the box because it sounded like a jet taking off every time I turned the blower on!

This will make a heck of a blower for the furnace! I will keep you posted.d
