.

in the time it takes to source, buy and ship the part, one could be fashioned from an AB tank, tubing and end caps.

just a thought.

I thought your ability would get the most accurate result.

you have a pretty clear photo of the item, which can measured against a known dimension such as a wheel or handrail height, and fabricated to scale.

or not. good luck.

what did they say,

necessity is the mother of invention??

I thought about it, but I want the correct part (especially if there is actually a size difference).  Close enough is okay, but I rather strive for the best result I can, even if it's eating my time and costs more.

well the AB brake reservior is a similar length and that's about it. the AB greatly differs from the air filter by having a tapered shell with the widest part in the center where the bolt detail is and the ends are narrower. You are better of scratch building the part with styrene and then brass strip for the center seam.

I'm not sure if this is the same part type but Des Plaines Hobbies sells an "Air Intake Filtration Unit" by O Scale America, item #OSA1038.

NO! John's lead is incorrect I have the bob rzasa similar part #1038 which is a dynacell semi ox yoke air intake found on the long hood of rebuilt geeps as the one shown below...

of course the AB tank is tapered, which is why only a part of it is used.

the tutorial goes like this:

use an AB tank of the correct diameter at the widest point at the center flange.

cut each end of the tank off on either side of the flange

add styrene tubing of the correct diameter to each side of the flange

add styrene end caps of same diameter

add piping detail

paint & install

vi-ola... done.

Dave,

If you can get me dimensional data on this part, I can draw it up in 3d cad pretty easily.  You can then send the file to Shapeways or find a local 3d printing resource, and have as many copies made as you like.  The part will be relatively small, so I don't think it would cost too much to print it.

Dimensions can either be hard data you get from a drawing if you can find a source, or a sketch where you approximate the dimensions based on this photo or others.

Let me know what you think.  Based on what I see in the photo, if I had good info, I could probably generate the 3d model and an .stl file in about 10 minutes.

Hello Dave,

The filter you are going to replicate is an air dryer to be more specific. Below the flanges is an area referred to as a dirt leg. Any sediment or vapor will collect below the flanges. From the picture supplied, I see a valve mounted on the bottom pointing directly downward. This valve would be opened occasionally to allow accumulated vapor and dirt to drain. They usually do this while it is under pressure (opened slowly of course). You might have a marketable piece to sell if you can produce them in quantity. Good luck with this Dave.
