John,
I have a Mark Williams 30101 rack, 10 inches long, 6 inches of travel in 2.25 turns so that is 2.66 turns per inch of travel. No idea what the ratio is. Takes 3/8 rod ends. You can make the steering arms on the spindles longer which will slow things down also.  $100 + shipping and it is yours.

Hey Rex...I am math challenged, but isn't that closer to 2.66 inches per turn....  :?  :|

I didnt spot that.

Imagine I am crossmultiplying here:

6 inches in 2.25 turns
x inches in 1 turn

1 * 6 / 2.25 * x = 2.66 inches.

And therefore:
2.66 inches in 1 turn or 360 degrees
x inches in 15 degrees (for example)

15 * 2.66 / 360 * x = 0.11 inches, and therefore 30 degrees one way from the straight ahead gives only 0.22" of rack travel  :?

John, while you were typing I measured our center load rack.  It has a total of about 2 inches of travel... yep it has been modified... and turns 270 degrees stop to stop.... with our 2:1 reducer we get about 1 inch in 270 degrees of wheel movement

Edit... just did the other math and both racks move the same...

I meant to say 2.66 inches of travel PER turn. Can't sneak any thing past on this site.


Thanks for catching that!

Scatter shield - tacked.

In the event that Mr Newtons Laws get involved with the unexpected failure of my flywheel or clutch does the propsed 1/4" steel 360 degree shield look appropriate (assuming a proper welder filled in the gaps)?

I am not sure if it needs to close in more at the rear where the bellhousing dips away from the steel bits or whether simply stopping them fly out laterally is required?

The rear face of the clutch pressure plate is approx. 2.5" as measured from the back of the engine block; the shield is nearly 5" in total distance from the back of the engine block.

 :cheers:

Sorry - these photos are right way up in my computer but seem to default to the orientation that the camera had when posted on the forum. Its good neck strengthening exerise looking at them, I guess.  :|

The purpose of the scatter shield is prevent injury from exploding parts... so welding everything is necessary... you are one of the folks it is protecting.  Email the pics to the SCTA special construction chair and ask if it is sufficient. 

To keep pics orientated run them through a program like paint and save them.... that is what I just did.  I did not rotate or anything else... just resaved them....

Here's my take on rule 3.0 (not to mention self-preservation) … The scatter shield needs to be capable of containing all the loose parts of a total clutch disintegration. Given the nearly endless possibilities of the directions those parts can fly on the first, second (or "umptienth") bounce, I believe a properly designed shield is one that prevents any of them escaping. Mine totally encloses the bell housing from engine block to transmission flange. Can't be sure looking at the pictures here is that's what you have, but I'll leave that evaluation up to your capable scrutiny!  :-D

Thanks both.

I will get them fully welded once I know what I have built is suitable - pics are with Tech but was wondering what the collective would note too.

Stainless - pics were 'righted' in the folder but not using secondary software - I will do that next time.

It looks to me that things could still be ricocheting around in what looks to be the rear of the bellhousing before the transmission.

(A hundred years ago, we made a 180º "legal" bellhousing shield on our drag roadster.  The clutch left the premises and took out the aluminum trans adapter, dropped the engine with headers down on the drag link and steered the car off the strip into the weeds.  Things happen.)

Will there be fuel/electrical/hot water etc. lines running on the non-shielded side?

Well – I was talking about the unshielded part back to the transmission flange.
