I can almost hear it running
Nice work as always, Steve!!! When are your heads going to get back to you?
Hmmm i'm really not sure Dave, MTS have told me they are being worked on as we speak and they could be done in a couple of weeks, then I have to ship them by boat as they are too heavy to go by air freight, it would cost a small fortune by air freight :eek:Quote:

Well whilst waiting for my heads to arrive I decided to make front & rear anti roll bars for the car, they are made from Chromemoly tube, 1" at the front & 3/4" at the rear, I'm using some Energy Suspension chassis mounts and an adjustable link each end comprising of 3/8" rose joints and some turned down stainless hexagon bar.
The dual blades each end get boxed off to stop any twisting.

You do outstanding word , very detailed--------however----------you don't want to make an anti roll bar out of a piece of tubing---------you might want do a little research into the twist properties of the material------

Not intending to start an argument, but I know that Competition Engineering commonly makes anti-roll bars from 4130 moly tubing, and Hotchkiss has some good design recommendations. Tubular sway bars are common on many factory cars on the road today. Heavy wall 4130 has pretty hairy torsional strength. I agree that tubular is a no-no if there is any bending. However, a properly sized tubular roll bar with the type of links that Steve has shown is definitely usable. Check the following link:

Wow!! I stand corrected!! Thanks for posting, Jack. It's always good to learn something!Quote:

Yep, I didn't do six years, but I quickly realized that the years at school taught us how to analyze, and where to look for answers along the way. I relied too much on the old approach and did not bother to look for new alternatives. I bet Steve has already looked at his tubing characteristics.Quote:

Most arb on modern vehicles resist roll by the bending of the bar itself--------
It looks kind of light, It's going to be awesome to see it in application!
Worst case, it breaks, and gets rebuilt or replaced.
Without innovation, you have stagnation.
Why not Jerry, its chrome moly tubeQuote:
