3T22/2T22 Dimensions?

[trevor229]

Hi everyone, long time lurker here. I am currently working on making a 3D model of the Federal Signal 3T22 to eventually 3D print (Similar to this one https://www.youtube.com/watch?v=5DrK3l0_t4E). I am trying to get the dimensions down to scale and there is very limited information in the service manual and I cannot find anything searching online. Does anyone have any resources for measurements or am I going to have to ask someone to take measurements for me? Any leads or info is really appreciated.

look up 'federal signal 2T22 & 3T22 siren manual' online the manual shows specs before & after assembly

For anyone else coming across this, I stumbled upon this video in which there are some (albeit rough) measurements: https://www.youtube.com/watch?v=4laOeraDF_I

For those who don't wanna watch the whole video, here they are:

• Total height (From the service manual) - 100 to 102"
• Chopper - 15"
• Stator - 19"
• Ports - 2" wide, 4 1/2" tall
• Tophat Cone - 19"
• Projectors - 13" diameter, 18" long

The only dimensions I don't know are the intake cone length and diameter (diameter seems to be the same as the motor), motor length/diameter, and the height of each chopper/rotor section (though its probably not much bigger than the aforementioned 4 1/2")

I did some math and found the approximate measurements from the image in the Federal Signal manual with the specific base image being from the 2/3T22 wiki article (Credit to Mrboojay). The motor height would vary between 3 phase and 1 phase if I remember correctly but I'd imagine this is a somewhat safe reference, though I can't exactly account for perspective warping. Hope this helps.

This is brilliant! Definitely will be of help, thank you!

No problem! I also forgot to include the heights of the cone and mounting legs, those are ~5.5" and ~53.5" inches (with 9" of that on the intake) respectively.
