Soundproof Compressor Enclosure | ALL-IN-ONE Woodworking Workstation – PART 5

 

 

Making the most of a small shop – PART 5

My All-In-One Woodworking Workstation has come a long way from being just an idea and has already made life in my small shop more pleasant and functional.
Unfortunately, I still needed to deal with some bulkier items cluttering up the floor space.
One of these items was my small 50L compressor.

Completed up to the end of PART 4.

Soundproof compressor enclosure

A compressor might not be an “essential” tool for woodworking but having a compressor at your immediate disposal does have a number of advantages.
Above and beyond these advantages, I just really wanted to get the thing out of my way. This is why I decided to build it into its own cabinet as an addition to my All-In-One Workstation.

Enclosing the compressor into its own cabinet meant I would be able to add soundproofing. Something I’m sure my neighbors would eventually thank me for.

The enclosure did, however, pose a potential nuisance. I wasn’t looking forward to having to open and close the box everytime I wanted to use the compressor. That’s why I decided I would build an external control panel that would allow me to start and use the compressor from outside the enclosure.

 

 

PART 5: Soundproof compressor enclosure

The instructions that follow are intended to be considered along with the visual instruction provided by the video above.

The layout of the completed bench.

Step 1: The Base

My first step was to add a base to the area I allowed for the compressor. This was done in the same way as the bases in the previous steps. By installing the base on top of planks fixed to the inside of the enclosure panels.

Because the gap was too large to fit one solid door, two small planks were installed to the right of the cavity that would allow me to install a panel to enclose that segment of the box.

The remaining area will be big enough to allow the compressor to be removed from the enclosure if the necessity arises.

 

Step 2: Side Panels

With the base installed the side panels were fitted.

The small panel to the left was just large enough to close the bench corner post. Onto this panel, I would later fix the hinges for the door.

On the panel to the right two cutouts were made. One was to install the external compressor controller interface while the other would be used to feed the air hose from.
The hole for the hose was cut only slightly larger than the coiled hose I was using.

A switch was installed to the interface cutout that was wired to a female power socket. The socket was installed on the inside of the enclosure.
The compressor would then be plugged into this socket and switched to its ON position.
This would allow me to start and stop the compressor by switching the external switch ON and OFF.

In addition to this, a pressure gauge and indicator light was also installed in the cutout.

Step 3: Hose Feeder

To keep the hose stored neatly inside the enclosure when it is not being used, a rod was installed over which the coiled hose could fit.

This meant that the opening between the rod and the face panel was just large enough to feed the coiled hose out.

The hose end was mounted on the outside of the box for easy access.

As a result, the compressor can be turned ON from outside the enclosure using the control switch.
When the compressor has reached the desired pressure the hose can be fed from the hole and be used.
After using the hose it can be fed back into the hole and stored on the rod inside the enclosure.

Step 4: Door

To complete the compressor enclosure a door was added.

To allow the compressor to suck the air it needs to fill its tank, a cutout was made in the door into which a louver was installed.

 

 

Step 5: Sound Proofing

The final step was adding a layer of soundproofing foam to the inside of the enclosure.

At this stage, I only added the foam to the sides. I left the top clear as I am still planning on adding a router table extension to the bench top.

Note: My compressor is not a piece of equipment I use all that often. If it was a tool I used on a more regular basis I would not have installed it in such a small space out of fear of overheating.

  1. I love this idea!

    I know you said you don’t use your compressor often, but I had a few thoughts/questions that might apply for others::

    1. Seems like the vibration when the compressor is ON could transmit through the cabinet & maybe affect other operations. Did you consider not including a floor panel do the compressor would be supported by the floor slab, instead of the caninet?

    2. With no exhaust ‘port’, I wonder whether just the volume of air available through the small air intake opening can also provide adequate ventilation to prevent the motor from overheating?

    3. I didn’t see on the video how you set up the tank drain facility & it’s actuation switch. Can you provide more detail about that?

    4. Did you consider ways to vertically mount the pvc pipe that holds the air hose? Seems like, if vertically oriented, gravity could help make it easier to store the hose after use.

    Again, this is a tremendous idea & these are only thoughts that popped into my head as I watched the video. So I won’t be surprised to learn there are good reasons notcto use any of them

    1. Hey Paul,

      The compressor does generate vibrations that are noticeable in other parts of the bench. It doesn’t affect working on other parts of the station but it is quite annoying. I am currently looking into making a small secondary base that I can mount on vibration absorbing rubbers.
      When the bench is completed according to the original plan I’m going to start looking at all the great input I’ve been receiving and see how I can improve the bench.
      The vibration attenuation is on that list.

      As for the overheating of the motor, that is a concern of mine. I figured I would closely monitor the compressor and then decide if it is necessary to add a panel fan along with another vent to allow a bit of airflow inside the cabinet. Unfortunately, the compressor has not been used much since its installation so I haven’t been able to determine whether it is necessary. (Probably is though)

      I will try and add the wiring diagram with some more photo’s of the start/stop/dump controller to the post soon.

      A verticle mount for the air hose is a great idea and one I did not consider. I’ll look at adding it to the list of mods on the completed station.

      Thank you for all the great feedback. I always appreciate peoples feedback.
      Cheers
      Jean
