ACA Allertor Restoration (new pics 2/14)

Figured it was about time I posted some pictures of the latest project. Two days after the April 27th tornado outbreak Ian and I ventured up to Werden Electric where I bought an ACA Allertor and a low tone model 7. Well after my little "adventure" in Dickson, TN with a funnel cloud it became painfully apparent that I too needed a large, powerful siren at my disposal in case we had one of those "oh s**t" moments down here. So I figured why not use the Allertor. After all it's almost as powerful as Charlie's 1000T, but not so powerful that my neighbors would kill me when it went off.

Here is the Allertor after I got home with it. The black and gray pieces are actually new housing components for the Werden P-127.

After I cleaned the grunge off and put it on display in the front yard. It was still fugly with all the holes, cracks, chips, and peeling gelcoat. Apparently it was so ugly that it killed the tree next to it

Fast forward to this year and I finally drug it out of that corner of my shop and started the restoration process.

The noisy part
Image

Armature out of siren for a much needed bearing replacement
Image

Typical wild looking ACA rotor
Image

What was hiding inside the rotor
Image

motor tag, same exact motor that's on the P-15 in Milan.
Image

The motor is in great shape, just all the grease from the front bearing had slung out into the barrel. The little pile of black stuff is crap that I cleaned out.
Image

Moving on, here is the old crusty turn table before it was cleaned up and primed
Image

Stator after being wire wheeled, deburred, sharpened, and primed. The large bearing in the picture is the front bearing for the motor.
Image

The housing after being sanded down and prepped for primer. The big dark spot is fiberglass resin jelly that I used to patch a big crack in the housing.
Image

Housing parts after extensive fiberglass repair and priming. There are lots of other sirens in this picture also
Image

The great void...
Image

Primer is grey, but my camera made it look blue. Notice the offset in the "tube" that comes out of the housing.
Image

Eden Prairie red? (filler primer)
Image

So today I drug all of the parts out in the yard and painted all the stuff that needed to be painted. I used Rustoleum Professional Safety Yellow thinned down to a water consistency with acetone and shot through a harbor freight HVLP gun. This is the same paint gun that painted the 2t22 and the P-15.

All of the parts are going to get one more coat of paint then I will start putting everything together. Stayed tuned for updates!

Looks quite nice. You've done some fantastic work on that unit.

HOWEVER....


BLACK WIDOWS?!?!?!

Yeah....even that picture gave me a severe case of the heebie jeebies. I'd have been so done with that rotor if I saw those....and on a witch hunt to see how many had gotten into my garage.

I do not do spiders! Especially deadly ones.

There are two things in this world that love sirens more than we do, black widows and wasps.

Very nice work, can't wait to see it installed and operating. Did the motor need anything other than the one bearing?

The motor itself is in great shape. I'm just replacing both bearings while I am in there. The front one had delubricated and rear one showed signs of having water in it at one time.

I've already pressed the new bearings on the armature so its ready to go back in. Just for size reference the front bearing had a 50mm ID, and a 110mm OD.

That's a huge bearing! Can't wait to see the finished product.

It is looking good!

Midwest City had Allertors. It will be good to see one new and bright yellow again.

I'll second that. If it's got more than 4 legs, I want nothing to do with it.

The Allertor looks good! I'd still like to see one in person one day. My brother describes them as an ugly, pissed off vacuum cleaner. He still digs them though. :D
