PTS flow bench build

The design of this bench evolved from a forum of enthusiasts with many succesful examples built. After building the bench, I can certainly attest to the design and though I did not use all the electronic gadgets that were developed for the bench,  the ones that I did buy and use work very well.

Plans and parts can be purchased from PTS Flowbench Technology: http://www.flowbenchtech.com/
PTS hosts a very helpful forum for those that embark on the build.

Here’s the final product:
