This should stabilize any side-to-side nonsense.

Yeah, they're just L-brackets, but every little bit helps.

Uhhhmmm . . . . .    Could you just bolt the inner end of those "torque rods" to the Chevy motor mount bolt?

That would still be technically single shear, but I'm thinking it would be stronger and eliminate redundancy.

Just my 2¢

AND, BTW,

They need to learn how to count to 60 in Manitowoc . . . . . . .

THAT "Manitowoc Minute", was a waste of 102 seconds of my life I'll never get back.

? ? ? ? ? ? ? ? ? ?

Perhaps the same could be said of this whole blog . . . . . .



Nevermind.

Insufficient angularity in the heim joint, different bolt diameter and need to leave room for header.

Oh man, I had to send this to friends in Kenosha, Racine and to friends at Motor Machine in, you guessed it, Manitowoc, WI.

Chris;

Your L-brackets look too wimpy for a single shear application. I think they will bend too easily, I betcha!  :-)

Can you replace them with thicker material or revise them to double-shear?

Neil, I see your point, but I think if the L bracket bends, it will likely be due to a motor mount failure.  The forces on it are primarily lateral - the upright is taking the bulk of the load.

If time permits, maybe I'll take a second look at it before August, but if I don't have time, I'm banking on the fact that we'll only be dealing with about 90 ft/lbs of torque.

Chris;

I think your problem will be due to engine vibration. Those thin L-brackets will flex and generate fatigue cracks, eventually failing altogether.

I guess I'm just trying to talk myself into thinking something other than "Neil's right again".  :roll:

I'll take a step back and see what can be done.

The Pommy Pygmy Playhouse is somewhat limited.  I've got a grinder, a drill and a jig saw, and I'm working on a daunting schedule that's looking less possible with every passing day.

It's been a while - I think I used to call this "the thrash" . . .

What's that you say?   You have enough 22 mph Bonneville time slips?     :roll:


Well . . . . .   you have, more or less, complete access to a better equipped garage, AND, a very well equipped machine shop.   Not to mention people who wish to see your project succeed and are willing to help . . . . . . for beer . . . . . .  

Yeah . . . . the downside is: they are in an another state!    But we are talking an hour travel time here, although you do need to learn:

RE:   Header flange Vs header primary pipe size.

Just a quick reminder:

The flange ID is 1.375" ID,   and the header spec calls for 1.25" OD pipes to start.   I would solve this issue with a short length of 1.375" OD pipe (say 1-3 inches) as a "doubler" with the 1.25" pipe inside.   Lots of quality headers are fabricated this way.   16ga pipes should fit inside each other without an issue.

It would be good if there is room to have the first 2/3 inches of the primary pipe straight out of the cylinder head.

Don't forget the merge collector.

A bushing in the heim end solves the diameter problem, and a spacer solves the offset problem.

A flanged bushing kills 2 brain cells with one blow . . . . . .

I know somebody who has a lathe available . . . . . .

I'm just getting worried.  There's simply no time in the budget for me to continue making rooky mistakes. 

Working today, but I have off all of tomorrow, and a three day weekend next week, and I'll continue to keep hitting it. 

But to your point, the 22 MPH time slip haunts me . . .

Weekend Update, uno . . . . . .

From the Wednesday morning Vulcan Mind Meld of 5/16/2018, (NO, I don't know what stardate that is . . . .) the mental gymnastics of one "wiggle pin" . . . . . .

Output from the brain of a terran  . . . . . . . .  NOT a Krell . . . . . . . .



And I still can't get the terran to change his default dimensioning specs from a limit of 2 decimal places.   Approved for production, nonetheless.

Things are happenin' below the dreaded . . . . . "cheddar curtain" . . . .

Und later: crankenshaften spinnin'   ja.

How thick?
How big are the 6 small holes on the major centerlines?
How big are the 2 small holes around the starter?
