Thanks Sid.

I got the Throttle body back from Geraldo today.

It's got a few scratches but nothing a good spit and polish won't cure.

Mounting holes drilled, shaft passage drilled and bearing seat done.

O ring groove cut both ends.

[tauruck]

I need to do the final drawing for the shaft and would like to use 3CR12.

All the sharp edges were chamfered and the two bearing collars are drilled and countersunk.
I opted to bolt the pipes together instead of using the V band Clamp.

I asked for ,2mm for squeeze on the bearings. I'll use one of the collars to also mount a circular
plate to enable the TPS adjustment.

Bracket for return springs and the actuator lever to come.

Ole Wilson is looking better.

There are some nice pieces going on that liner Mike!

Thanks Pete. Necessity is the mother of invention hey??.

Loving every minute.

This "little" job took me about 5 hours.

The throttle body actuator arm/lever thing!!!!!.

[tauruck]

There's no lathe or milling machine here so I used
the drill press, grinder, belt sander and elbow grease.

The plate is 10mm thick and needs to be milled down
to 7,5mm on the small end for clearance on the clevis.
I'll get one of the pros to do that. After that I'll polish
and final finish.

I drilled and tapped an M5 for locking on the shaft.

I was thinking of using a grub screw on the other
side of the lever just for insurance. Gotta go.

Huge Thunderstorm headed my way.

This is my hydraulic gas pedal setup.

The pedal and floor mount are stored at present.

I'm just thinking about the return spring I want to
use on the throttle body?. Will there be a conflict
on using this system with the spring?. I know you
guys will have an answer. Thanks in advance.

My mind is blank right now probably because of lack of sleep.

Mike,
Did you get email about OD of runner?

Mike, be very wary of a hydraulic throttle. As the fluid temperature rises it expands ( just like a thermometer) and moves the throttle position.

No sorry I didn't.

Thanks Neil, point taken. Any ideas on the return spring?.

[manta22]

Just the usual advice, Mike- use two springs. I had a car that used two coaxial springs- one inside the other-- the springs were fairly light and six inches long or so. It worked fine until the coils vibrated together and both springs bound up at half throttle. That was on the street. Fortunately I got it stopped without hitting anything.

Ok, thanks Neil.
My gut has never let me down.
If i'm not sure I ask and you guys always come through for me.
God Bless you. You saved me a heap of heartache.

The SCTA Rule Book (I think) requires two springs.

Which brings me to one of my (too often) tales in Inspection. 

This one includes a very-experienced well-known old codger (even older than I, I think) who approached the Roadster and said something along the lines of "Well, this isn't going to go good.  You've got your lug nuts on backwards."

I replied that they were tapered on both sides so I wouldn't and couldn't have done that.

He looked in the interior and asked "Is this a new car?"  I guess I should have taken that as a compliment, but replied, pointing to the 6 or 8 red record plaques, "No."

Being right next to the Registration line, we were now drawing a small group of onlookers.

Then – "Push the throttle all the way to the floor – now let it loose."  I did.  He said, "That sounds like two springs."

"No, that sounds like three springs."
