Reducer Quiz
For the last week quiz I didn’t receive any answers at all. Maybe it was my fault because I didn’t explain the wrong way of the blocker installation, but maybe, simply, nobody gives a …. about topic like this!
So, I decided don’t wait another two weeks for the right answer, but to post the next quiz – maybe next one will be more successful!
So here we go:
Yesterday I was working in old commercial building replacing old heat runs. Almost all of them were 9” round pipes and fittings – odd balls, and my task was to replace them with 8” fittings, pipes and diffusers. At the same time my boss told me that I have to save as much old stuff as possible in order to help him to save some money. I‘ve been told that he will buy some 9” to 8” reducers which will terminate every 9” heat run I able to save for the 8” flax. When it comes to the time to give me those reducers my boss found out that there are no such things available at all! There wasn’t any supply house in entire Detroit aria caring things like this!
He was lucky enough to find at the shop a few 9” round caps and 8” collars to make the reducers, but for the rest of the 9” heat runs he come up with another bright idea: replace them with 8” collars, pipes and fittings! As a good employee I’ve said – all right, but for myself I’ve said – no way!
I’m not crazy to take off the 9” take offs, patch the holes, cut a 8’ collars in and run the pipes with fittings when it’s all already done and I need just a few lousy reducers! Luckily I found some 9” pipes and made the reducers in no time!
How Did I Do It?
P.S. I know that most of the visitors of my website don’t have a clue about ductwork installation, but in secret, I can tell you that this quiz is not about ductwork installation at all it’s about geometry!
But if you a self -employed contructor or thinking about ductwork installation seriously you may need to know how to make field made reducer (I’m actually know two ways of making them). At first try to find the right answer or for the price of only 
1.99 I can explain how to do it.
