Dehydrator Plans

There was a brief article in the August 2021 PIPER MAGAZINE and would like more details on the plans to build and assemble and operations.


  • Gcox:

    Already built engine dehydrator units are available from most of the major suppliers. Here's one from Aircraft Spruce:

    If you are a DIY person, then the internet is your friend. I typed "DIY airplane engine dehydrator" into my search engine and it listed dozens of articles and videos. Some articles were for other aircraft brands and experimentals, so you'll have to adapt their plans to your plane, but the concept is the same.

    YouTube also has a number of videos on how to build your own engine dehydrator. Check them out and let us know what you decide!

  • @Gcox652021, this was my article, what details do you need? Glad to help.

  • Joshua, where can download the file for the 3D printed oil fill adapter? I’d like to print one out for my dessicator. Thanks!

  • Here is the .stl file. I had to compress it for the site to allow me upload it.

  • Joshua, Thanks! Part looks awesome!

  • Hi Joshua, I am putting together the parts for a dehydrator. Where did you get your silica beads?

  • I just finished a homebrew dehydrator and created a 3D print for an oil dipstick to 1/4" barbed fitting - uses a 7/16" o-ring for the seal. If there's any interest, I can see about posting the STL.

  • Hi, I would be interested in that STL.

    Here is the Adapter and the attached STL file (zip form).

    Adapter with 1/4" barb fitting for Continental engine (TSIO-360) dipstick. Used for homemade dehydrator. Uses a 7/16" O-ring. Sliced using Prusa Slicer using 0.15mm layers with 3 perimeters, 30% concentric infill and no supports. Printed with PLA and it will melt if used on a hot engine. Some minor cleanup of O-Ring notch may be needed. Fit with a 7/16" OD O-Ring into the groove near the bottom, attach a 1/4" ID hose and it should fit snugly into the top of the dipstick tube. Comments and suggestions welcome.
