Horn Button/Center of Steering Wheel?

Since I started this build, I've been working hard to figure out a way to get the horn button in the center of the wheel. Once I saw DV/DT's turn signal mod, I figured out a way (Ford Probe Turn signal). Thanks to DV/DT, I stole your idea and ran with it. I figured if I found a horn button small enough I could machine a center cap for the steering wheel and install a nice little horn button in it. Turns out Grant sells buttons for their steering wheels separately. I found one with a Ford emblem on it I liked and then needed to find someone to machine the part for me. Enter Cannonball Cobra (Paul M). Paul has been a great help and true Friend throughout the entire build. Paul just happens to have a machine shop in his garage and when asked said he would be happy to machine the part for me. He modeled the base after the stock FFR piece and on the button base I gave him free reign. I would have been happy if the finished piece was no thicker than an inch. Paul had no intention of letting it end up that thick and manage to machine the actual Grant piece down a bit so the finished piece is only 3/4" think. Exactly the same thickness as the hub supplied by FFR. I keep telling Paul that a bunch of people would want this piece on their car. He is convinced no one will want to pay the cost that the machining take. I don't know? I would. Even though I have tried to compensate him for the material and his time, He's having no part of it. Maybe he'll let us have him over for dinner. Well Thanks Paul. I've said it to you many times already but, here it is again. I am very happy with the finished piece.

Wow, that's nice!!

You guys have got to quit coming up with these things!!

Fantastic! Soo many ideas it's hard to not want to do all of them. This is one that I'm gonna save till after the build. You know, something you don't have to pull the body off or pull the motor.

Very nice job! I want one!

Frank, what's the diameter of the plastic horn button? Mine says "Momo" on it and I would like to change it out, if the Grant one would fit. John

Paul and I have been bouncing ideas back and forth. Machining and material I would guess near $250. Pricey. But I really wanted it to look OEM. In instances where you weren't using the Probe turn signal unit, Paul and I figure a piece of coiled microphone cable will work. winding and unwinding as the steering wheel is turned. Prostock drag cars use this same type of cable for line lock and parachutes on their steering wheels. Frank

Stupid question. How you gonna wire it withouut a hollow column?

Lex, Its pretty easy. I am not going on the inside of the steering shaft. If you look at the back of the FFR hub, it's bigger on the back than the shaft. The wire will feed down a hole drilled in the hub and fasten to the shaft to the Probe canceling unit. I'll post more pics. when I get that far. Only have the wheel assembled for now. Once the dash is installed it will be clearer. Frank

I have also done a horn in the center of the wheel, it works but it is not nearly as simple. Mine cost me $200 (to get the machining)(done. (if it is any help) Mine uses the stock FFR hub, center section and decal.

Guys,thanks for the kind words.
Kudos to Frank for coming up with the Idea in the first place.

I made my horn button using the Grant's Billet horn button that I got from Summit Racing, that with a little elbow grease and I have really nice horn button that only cost me around $35.00 total. Picture isn't the best but gives you a good idea.

Lile. We looked at that exact method. I was just a little worried about adding more holes in the steering wheel. and the way it lays out it looked like one or more holes would overlay the ones already in the wheel. Yours came out great. Frank

if you want a horn button in the middle of your steering wheel, look at finishlineaccessories.com or europaspares.com Both have cobra logo horn button bosses. Thing is, i think they both sell them for 9 bolt steering wheels. I may be wrong, but check them both out. europaspares has them in aluminum (shinny) and Finishline has them in the black boss style seen on AC cars today.

Frank, if you are careful the holes don't overlap any of the others at all. All I did was drill the holes deep enough so I could tap them and run the screws in. I woud explain the rest of the install but it's not that easy to explain, I can maybe draw a picture of the install and post it on here so others can see howt's done.

Very nice work. Looks great. You guys never cease to amaze me. I have to do another build that's all there is to it...
