I dug this up while foraging through my crawl space, looking for a couple tool racks.

I'm not sure if I ever posted this before, but this is what a scratchbuilt controller looks like.

Yours, Mike?

 

When was that controller built/used?

I built it in probably early 2002.

I won three Nats Championships with it, in 2002 and 2003.

Among its features are:

1/4" Lexan sheet frame/handle.
Solid brass bar trigger.
Telescoping, spring-loaded wiper button (basically a miniature shock absorber).
Paint job by me.

With the amount of work I have in it, there is very little chance I'll throw it away.

Is K24 the model number? What did K22 look like? And K16?

It stood for Koford 24 band.

I think at the the time, 15 bands was the max any commercial controller had.

The switch block was made from K&S brass strip, Plastruct tubing, a couple Koford 3/32" axles, and diaplane material.

It's interesting that Group 7 racers went from resistor controllers to electronic and back to resistors again (simplicity and easy to repair).

 

Cheers.

That was the theory.

I was seeing too many electronic controller failures (probably from hooking up wrong).

You really couldn't blow this thing.

Mike, 

 

I may have missed something in the evolution of the resistor controller, but where do all those wires go?

To the three connected resistors coming out of the side of the box.

It's just an external resistor controller, but with three resistors instead of one.

I never kept track.

When people used to ask, I would guess 80 hours, plus or minus 30 hours.

When I graduated from plastic track to racing on wood, approx 88/89 I had no commercial type stuff and little money. I crafted this for club racing using materials I had except for the ohmite 4 ohm resistor. Let's see if anyone can identify the origin of the handle! 20170223_115450.jpg

Very cool, Chas.

(Chas is a mail order customer of mine)

Is the grip something to do with archery?
