Harvey’s “Counterfeit” Beacon

by Harvey Hartman

When I first started erecting my vintage airway beacon tower, I was unaware of its historical significance. I simply wanted this cool old beacon for our airport. Therefore, an exact restoration wasn’t in my original plans. While I DID erect the tower close to its original condition, I took a few liberties to upgrade it in a few structural areas and improve its beacon and electrical system. The control system (still in progress) is being brought up to modern standards and will include a receiver that will allow a pilot to activate the beacon from his/her cockpit prior to landing. (i.e. PCL, or “Pilot-Controlled Lighting” in FAA terminology.)

The Original Vintage Beacon

Crouse-Hinds model DCB-36
Crouse-Hinds model DCB-36
The beacon that came with my tower was a 36″ diameter Crouse-Hinds model DCB-36, was double-sided with two very-expensive Fresnel glass lens sets, and was equipped with two 1,200,000cp (that’s 1.2 MILLION candlepower!) bulbs. (One was the in-service bulb and the other bulb was a backup mounted in an automatic bulb-changing mechanism.) Introduced in 1932, this model quickly became the standard beacon for the Federal Transcontinental Lighted Airway System. It also eventually replaced most, if not all, of the earlier beacons as normal wear and tear, as well as storms and vandals, took their toll. (The big DCB-36 is also noteworthy in that it was chosen by the Lighthouse Division of the Department of Commerce in 1936 to upgrade its coastal lighthouses from carbon arc, and acetylene-powered beacons.) However, the venerable DCB-36 design is now 85+ years old and replacement parts are getting hard to find. And those parts that ARE still available are getting very expensive. Therefore, I made the disappointing decision to not reinstall the historic original beacon. Instead, I built a stand-in (a stinkin’ counterfeit, if you will) beacon to put on the tower and the original beacon will be restored and displayed inside my hangar where it’ll be safe.

Building My “Counterfeit” Beacon

Due to my decision to not reinstall the original beacon, I set out to find a replacement beacon. I quickly discovered that new (or even USED) beacons aren’t cheap!!! Not one willing to forfeit quality and style for an affordable price, I elected to design and build my own; a substitute with two priorities in mind. The substitute had to be robust and cheap to maintain/repair, and it must look like something out of the late 1920s – early 30s.

With the tower being a late-1920s model, I decided to model my homemade beacon after the earlier “double-drummed” beacons. (“Double-drum” is slang for beacons that use individual housings, or “drums”, mounted back-to-back to produce the alternating white and green flashes signifying the location of a civilian flying field. The later “Single-drum” beacons such as the DCB-36 used one housing that contained a single bulb in the center with a green lens on one side of the housing and a clear lens on the opposite side to produce the two flashes.

I decided to model my “counterfeit” beacon after the 24″ double-drummed design. However, my fondness for old steam locomotive headlights and America’s glorious 1920-30s Art Deco period may have also influenced my new beacon’s design.

And while it will be virtually impossible to stop the storms and vandals, at least I can make their damage less expensive. Therefore, my stand-in beacon uses common yard floodlights instead of the exorbitantly-expensive high-powered metal-halide bulbs and Fresnel lenses, and its housing is constructed of thick steel instead of cast aluminum like the original. Unfortunately, it was beyond my capabilities to construct a replacement for the original rotator base so I’m reusing it for the time being, but with a steel shield added around it for increased protection.

My new beacon had a humble beginning as an old propane tank which donated its heavy steel end domes to become my new beacon’s backshells.

I then built their mounting yokes and an adapter box that would mate the beacon to the rotator’s output turntable. This completed the basic beacon and its mount.

The Ring Shields were fabricated next and the visors followed. And this was the end result.

A trip to the powdercoaters resulted in this sexy thing! Gratings were fabricated and were added in front of the bulbs to prevent birds from attempting to build nests during the day when the beacon is stationary. From ground level, these “platinum silver” grates look like fluted glass lenses.

The beacons’ elevation angles can be adjusted using this simple jack screw device between 0 degrees (on the horizon) to +20 degrees above the horizon.

We hoisted the “counterfeit” beacon to the top of the tower on 9 April 2016.


Note: The bright white “dot” centered under the beacon in the video is a floodlight that illuminates the windsock when the beacon is operating.

That’s where my “counterfeit” beacon and its tower are as of January 2017. I still have to design and build the PCL system but as the video showed, the beacon can be operated manually for demo purposes.

October 2017 Update

I have recently located and purchased an original late-1920s “double-drummed” Crouse-Hinds DCB-224 airway beacon to replace my “counterfeit” beacon.

I suspect that your first question is probably wondering why I’m replacing the homemade beacon that I spent so much time and effort building to replace my big DCB-36? The simple answer is because it’s not original. It’s incorrect for me to call my beacon tower project a 1920’s Airway Beacon when the beacon itself is a 2016 product. “BUT, (someone is bound to point out) the reason for not reinstalling the DCB-36 was to avoid exposing an historical artifact to potential damage. How is putting up a different antique beacon going to change that?” My reasoning is that while it would be virtually impossible for me to prevent such damage, at least I can make that damage less expensive to repair. I accomplished this by designing my homemade beacon to use common PAR38 landscaping floodlights with their built-in lenses and reflectors, instead of the original beacon’s hugely-expensive Fresnel lenses, and special bulbs. While the large, double-sided design of the 36″ diameter DCB-36 would be difficult to modify, the twin single-sided DCB-24s can successfully use the same PAR38 bulb system as my homemade beacon. This will allow me to say that both my tower and its beacon are alumni of the old Federal Transcontinental Lighted Airway System.

So what’s going to happen to my homemade beacon? Of course, it’ll still serve duty on my tower until the rebuilt DCB-224 beacon is ready to replace it. However, my ultimate plan has always been to have an operational beacon on my tower AND a backup beacon in reserve that would replace the in-service beacon when it needed major repairs that would likely render our airport’s beacon out of service for an extended time. My homemade beacon will serve that purpose well.

For the purists out there, please note that my “PAR38 modifications” are not permanent (i.e. the drums are not drilled, cut, or otherwise irreversibly altered); therefore, the drums can easily be returned to original condition someday. (Unfortunately, the same cannot be said for the propane tank used to create my “counterfeit” beacon.)


July 2019 Update

Harvey's 1947 Luscombe Model 8A "Silvaire" provides perspective as to the size and scope of his tower's restoration project. The 2-seat sportplane has a 35ft wingspan and a 6ft height.

  1. I am a private citizen trying to transfer a 1939 tower (very similar to yours)and beacon from a local paper company site to the town of Ticonderoga airport. In order for the town to accept this gift they need to know the weight of this tower. Could you help me with this? It is a 55’ tower with a 24” rotating beacon. Anything would help. Thank you.

  3. My spouse and i are part owners of the Beaver Marsh airport near Chemult Oregon and are in the second year of a lighting project and water source for EMS and Firefighting.
    Might I ask where to find those VERY EXPENSIVE lens for the beacon or what your recall of the cost was?

  4. Howdy!

    Wow! This is such a fantastic project, and amazing restoration. Someday I’d like to do a setup similar to yours. As a lighting and aviation history enthusiast, it’s great to see others who have similar interests and hobbies. Did you custom build some kind of flasher unit for the obstruction light above the beacon? I also see you found a good spot to mount your AcuRite station!

  5. I am looking for 2 light bulbs and something that looks like a coil on an older car, only taller. Would like a diagram on how to wire it. Here is my information that I got off the beacon. BEacon DEA 022, ID FAA L801, 120 V WATTS 1750 MAN.P/N 0200, APPOLLO LIGHTINGS CO. Columbus,Ohio . THanks for any help!

  6. Hi,
    Do you know where I might find information on an antique Crouse Hindes search light? I l can send a photo if you write to my e-mail address.

  7. Harvey –

    Thanks for a great article. This is really inspiring!

    I own an early 500 watt Westinghouse “on course” light. As you probably know, these early navigation aides were mounted below the rotating beacons on the early air mail navigation towers.

    Steve at the Cibola County Museum in Gallup, New Mexico was able to establish, from the serial number of my Westinghouse “on course” light, that it was manufactured in 1930. My “on course” light came from the small town of Blair, located near Omaha, Nebraska.

    My light is complete and original, except for the interior lens, which is missing. This is a 10″ lens. I have been told these interior lenses came in red, green, and clear colorations.

    Do you have any idea where I could obtain a 10″ interior lens for my Westinghouse “on course” light? I don’t need the mirror, I just need the interior lens. I will settle for any color I can find.

    I will appreciate any information you can provide.

    Thank You!

    • Christian, my name is Jason and I am in Florence Arizona, I have a restored course hinds beacon with a code disk and I am in search of both a red and green course light. Let me know if you are interested in selling.

  8. Man, that Harvey is one super-talented dude! His wife should let him spend more money on worthwhile projects like this!!!
