I did get a few hours to work on that clutch setup some more...
Finally located a clevis the right size to attach to a 3/8" rod and the clutch pedal...
Ran down about 3" of 3/8" fine thread so I'll have lots of adjustment available...


Looks good to me, will add another hex nut weded to the rod below the thread for a wrench...


Cut and welded an offset from 1/4" scrap to set the "push" point 2-3/4" down
from the pedal pivot, and 2-1/4" over to the left to center on the clutch MC...

Now I need to cut the rod to the correct length and round off the end to match the MC piston...


And I need to learn how to use that bore scope I just bought to check clutch gap, and figure out just where I want to put the access holes...

Been busy on other projects, but did get some work done on the brakes and the hydraulic clutch setup, here's a few pix:

Got the clutch pedal, clutch mc pushrod dialed in pretty well, now to see how well it really will work with this mc to activate the clutch....


The two bolts holding the offset for the pushrod on the clutch pedal was rubbing on the steering column, so I cut the heads off and welded the bolts in place, works just fine....
Also the upper hole centers the pushrod on the mc piston pretty well, so using that one...


Had to find some an-3 braided brake hose and fittings to extend the short piece I had on the slave cylinder. It ended up too long, so shortened it and changed the 90 at the mc to a 45....


Decided that before I go mounting the clutch mc in place I'd better get the brake lines installed at that mc...


The rear outlet on the proportioning valve had a weird, large thread, but one of my local auto supply houses was able to find a fitting that matched it....


Bought a few 3/16" by 60" hard lines and started fitting them to the chassis, shortening and reflaring with a double flare where necessary...


Attached the brake lines to the frame using pieces of rubber hose and clamps...


The rubber hoses at the brakes are 1980 Camaro, fit perfectly, after I moved the calipers from the rear mounting holes of the spindle mount to the front...
I think they'll be fine that way....


The passenger's side...


I still need to add some more mounting points using the rubber hose and clamps, and still need to put the rear axle hose in, again using one for a 1980 Camaro....

This is one of those threads I follow religiously. Can't wait for another, "new installment". I like the do-it-yourself, using NO pre-fabbed kits, to put this old Hawaiian 55 Chevrolet back together, into something completely new to Hawaii, and probably anywhere else. I see photos, someone has posted, of the 55, 4 door, Olds powered and blown, Gasser on other sites. Everyone is impressed. Can't wait for the first go-around-the-block ride. Keep it up Willy!

I was out driving the '55 gasser, "Patches", yesterday, still is a "gas" to drive it, love that car, the "new" TKO 600 I put in it to replace the Doug Nash 4+1 I kept breaking is not that good, shifts really hard, it feels like the synchro rings are jamming, not sliding past each other smoothly on each shift, but it is driveable, and except for the shifting, a ton of fun to drive...

I was thinking there was something wrong with just my TKO600 due to the hard shifting, is this a common problem?? I paid "extra" to get the trans built with the graphite (is that right?) synchro rings, not sure I have described that correctly, and I'm thinking that was a mistake, am considering pulling it apart and rebuilding with brass synchro rings. I've a lot of experience with Muncie's and my old Doug Nash, can't imagine that this TKO will be any harder to work on, and maybe I can improve it....

i was told those syncros helped. i never had them
in my tko. i was used to the muncie's and t10. i hated my tko and got rid of it. other people have
had the same feeling about tko. others like them.

yup, I agree with every word!
It would be interesting for me to look inside and try to determine why!
The design of the synchro rings in the T10s and Muncies (and the Doug Nash 4+1 I still have)...
They shift great, maybe I can adapt that to this tranny??
Where's the bar....

Miss my chopped panhead, gotta get it running...

Visiting family, house and yard projects, have slowed down
my progress on the '55, but did get some work done
on the brakes and clutch systems...

Still getting way too many leaks, have had to pull off
just about every one of these steel brake lines and
redo the flares, and try different connectors....
These are various length steel brake lines from NAPA,
but I am getting leaks from just about every one
of their flared ends, it's been a nightmare !!

I've had to reflare and refit every connection at the MC
and proportioning valve....




Front line from the proportioning valve down to a tee,
then off to both front calipers, used hoses for an '80 Camaro,
they fit nicely...


Got the front brakes hooked up and bled, looks good...


Ran two 60" lines along the frame to the rear, had to cut and fit
a short piece in the middle to get it exact...




Got it bled and the pedal feels good, but still chasing a couple of leaks !!

Got the hydraulic clutch bled and working, but the pedal feel is much
heavier than I think it should be, need to check that out...



Lots more pix HERE and HERE

More later....
Willy

Dug out my valve spring compression gage....



....And used it to press against the clutch pedal,
it's running between 35 and 45 lbs pressure, so I'll use 40 average,
with this system I designed the mechanical leverage factor
is 5.5 to 1, so with 40 lbs at the pedal I'm putting 220 lbs
on the clutch release lever at the slave cylinder...
For this aftermarket '93 LT1 T56 clutch setup I
don know if that is excessive or not. It sure feels like
a lot though....



But I've decided to just leave it and drive it this way and see how it feels...
I still need to setup an adjustable "stop" and install the over-center return
spring on the clutch pedal, and then see how that feels....
More later,
Willy

Dang Willy, I'd be involuntarily committed about now if I was having those issues; well maybe a little bit longer trying, but the results would probably be the same. If this build does't make it into one of the magazines (Hot Rod, Car Craft, Etc.), especially being in "remote" Hawaii, I don't know how that would't be possible. I know you'll get it all figured out; leading the way is always difficult. I am Butch/56sedandelivery.
