Clutch linkage redo

[Aukai]

I'm a rookie at machining, so being able to play with some of the gadgets, even though not needed, it's good to practice. I used a new center finder/wiggler for the center punch hole. I got the clutch linkage to clear the header 2.250" top pipe, and bottom pipe today. The top was just a matter of straitening out a bend in the linkage, the bottom was more involved. My first eyeball adjustment came in needing 1 more inch of clearance to get full pedal travel/ release. Reshaped the linkage, and moved the hole for the adjuster, then added a stud ( grade 8 bolt )with a spring clip hole to use a new left hand, right hand double heim. I'll Get a close measurement tomorrow, cut the CM tubing, and add the threaded ends. Then check to see if I get the right air gap measurements for the pressure plate, and disc .070.

Cool - new toys!

That is a beefy linkage! Brings to mind those old Zoom clutches that were a good substitute for a leg press machine in the gym. Had one in my 1970 Olds W-31 when I was a much younger guy.

HAHA, I remember the Zoom clutches, I never had one that did not chatter, they used to be about 2000 lb base pressure. This one has adjustable base pressure, and you can add weight to the fingers for added pressure that is RPM sensitive. Base pressure here will be in the 300-600 pound range, with the added counter weight. There are all kinds of nuts, bolts, steel, aluminum, also, half nuts, different washers all weighed for grams, and calculated for weight added at selected RPM.

Probably not a cheap clutch setup you have there. Things have come a long way from the 60's in that department. I remember using neutral at stop lights to avoid trembling leg syndrome. The Heim joints work well, also helps using roller bearings, or bronze bushings on the pedal assembly. Automatics are starting to look a little more attractive at my age, but there's no substitute for rowing through the gears. A few pics of the setup we did on my sons car. A lot of slice & dice, fabrication, and judicious use of the BFH on header tubes. Kinda fun making it all come together. Cheers, Mike

That is a complicated looking setup, but as long as it works. I have never had an automatic in my performance cars, I wouldn't know how to act without a clutch.

Well the new linkage is assembled. I'm not going to weld it yet, wait till I can check operation.

Is this for a drag race car?

I believe It's a grocery getter, for "fast food". Mike
