Photos of Some Recent Custom HVAC Fabrication

Here are a few photos of some recent fabrication that has left the shop. Business has been slower but not totally dead.

The first photo was an order for two 25 x 16 to 25 x 10 cold air boots (aka buffalo boots). These are as common as plenums and trunk duct when it comes to installing a forced air furnace. These are for a retro-fit change out in town.


The next photo is a basic plenum, customized with a flat top instead of a normal plenum style cap that would recess 1/2" down inside the top of the box. The customer needed a flattened top for this particular installation.


The last photo is a small order of trunk duct and some small fittings.


Nothing fancy, just a few photos showing the kind of work we do on a daily basis. All of these items are custom made and are what keeps the shop moving along. We concentrate on the residential market consisting of smaller HVAC companies and homeowners with some work coming from very small commercial clients.

Oil Hits $110/Barrel, Our Input Costs Continue to Rise

Seeing that Crude Oil hit $110 today, I thought I would post a few charts showing the performance of oil, gas prices and steel over a one year period. As you can see, all three have been moving consistently to the upside over the course of the last year to date. This is troublesome for a number of reasons both personally and from a business standpoint.

Sheet Metal Prices Continue to Rise, Hurt Margins

Our input costs are quickly rising. The load of metal I received Friday afternoon was the highest metal has been in over three years and until oil and other commodities stop rising, I see no end. A 25% increase in our metal price since the end of the fourth quarter 2010 is a tough pill to swallow. This scenario is a killer for our business because

Fabrication of a Custom Access Door Frame: Day 1

Here is what I am working on this afternoon. A customer needs a door fabricated to fit on this pre-made 12" round fitting. So, after a bit of drawing and thought, I came up with an idea for a frame that I can fabricate separately and bolt on. Today was the day to build the shell of the door frame and map out where to cut the hole on the pre-made 12" round Y-fitting.

Here is the pre-made fitting that

Fabrication of Custom Exhaust Hood For Screen Printing Shop

Even though duct work is our bread and butter and what the majority of my work day consists of. We often get projects that are along the same lines, but just different enough that some extra thought and attention is needed. Case and point, the project I had for the last few days has been to fabricate an exhaust hood for a drying machine inside a small screen printing shop. I won't even pretend to know exactly what the machine does, the customer drew up what he wanted and I am making it to those specifications. Simple. Here's some pics.

Below is the wide shot of the hood. The customer wanted a rectangular box with pieces angled inside that would deflect the air to the center 4" collar.There are no welds, everything is done with the Pittsburgh machine, break, hammer and rivets.

This picture just gives a clearer view of the depth of the piece and a look at the collar in the center. The total dimensions were 62" wide, 6" deep and 12" in height with a 4" collar cut into the top middle.

Here is a shot looking inside at the angled pieces that will deflect the air toward the center of the hood.  It's tough to see, but I also added a 1/4" 90 degree lip around the bottom edge for some stability. Even though the hood is for a smaller application, the width of the hood will make it weaker in the middle and prone to bowing or popping. The angle will give it just enough strength to keep it stable when the machine is running and keep any noise to a minimum.

A Full Day Of Custom Fabrication

Thought that I would post a couple pictures of what I worked on today. It isn't everyday that I get to make all custom fittings. Most days are filled with stock duct and maybe a few easy custom things. I enjoy a day that sees a custom fitting go from mind to metal.

The top photos are of a custom condenser cover. They are very basic because the customer wanted something less expensive. The bottom photos are a custom U-shaped elbow for running the duct under a support beam. The customer didn't want to fool around with cutting and fitting stock elbows on the job.
