I have seen pictures on here of the Allen Generator Test Stand, lovely bit of kit but I'm unlikely to be in the position of owning one. I wonder if anyone has made their own system of driving the generator? If so would be interested in what motor you used to drive the generator and what coupling method to the generator is used, maybe some pictures please? Thanks John
John, here a picture of my home made Generator test stand. It is driven with a v belt at about 1680 RPM. When you like to have more information please let me know, or better cross the pond.
John, behind the Ammeter and the volt meter there are three light bulbs , nearly the same as Model T lights, so you can see how the generator is working under load.
The Allen Electric generator tester I have has a 1725 RPM 1/4 HP motor with direct drive.
Here is a photo of a homemade unit I made with some additional features I wanted; A headlamp load (not visible and mounted on the back of the panel) and a panel voltmeter. The drive is a reverse casting of an original generator gear, but many have cleverly make one from an old generator drive gear that works very well.
Here is a photo of the modified drive gear.
I can send you some additional photos if you like.

I just slip a piece of Model T radiator hose over the gen gear & motor pulley and fasten with 2 hose clamps. Fast, easy, cheap & flexible.
Anyone have a schematic?
Wow thanks guys that sure given me some ideas to proceed with building one of these. I will first look out for a suitable motor to drive the generator. Thanks again, John
I built a tester to demonstrate my voltage regulator when I first offered it for sale many years ago. I wanted to show how it worked at various speeds. I found that a newer top end Craftsman 3/8" variable speed drill had enough power to operate the generator through its whole range. I mounted it in a box with a cut down steering column end with throttle lever and quadrant pushing a cam on the other end of the lever that pressed against the drill trigger. Most of that Rube Goldberg linkage was hidden. It was not a generator tester per se but rather a VR demo box. I will see if I can drag it out and take a picture of it for you guys. My good friend Tony Verschoore who always liked to heckle me, was in the group of guys I was demonstrating the VR to when he then asked rather loudly from the back of the group "I don't need a VR but what do you want for the nice generator and box?" I miss having him around.
