Jerry,
I don't see where anyone but you has held the Hotchkiss information to be any type of engineering thesis or analysis?? I simply pointed out that in that information they referenced that several of the OEM's are now using hollow ARB's as a regular part of their design process, allowing them to tune the suspension by simply increasing or decreasing the wall thickness of the tubing. Porsche was one cited, and I find it difficult to imagine that the suspension engineers at Porsche are concerning themselves with pennies saved, nor that they're focused on straight line acceleration. It's purely up to you, but I don't see any need to further pollute Steve's build thread with more discussion of tubular ARB's. Seems that they are widely used in the racing world, as well as in production design, and only a few of us fossils didn't know about it. I, for one, appreciate being set straight and learning something new.

Steve, I really like the final finish on the end pieces. Great work!!

Just to throw another spanner in the works guys but all our touring race cars use moly tube ARB's, they corner quite hard.

Steve----what is the wall thickness of the tubing your using??????????Sorry to create controversy??

I was reading some of your posts about liking the 60s machinery-------so do I, except my Pratt & Whitney lathe is supposedly off an early 40s boat----I've got 3 bridgeport mills plus an Index mill, 20 inch bandsaw(new in 1970) 2 Lincoln tig(one new one old) an Linde heli arc that was owned by a company that built stuff for the space program(some of the stuff they left on moon was welded with this machine)

Jerry thats top secret information Or in other words I can't remember I think its .90" but I will check and let you know, Its what Andy Robinson Racecars use for their ARB's

Steve you always make this look fast and simple. In stainless no less! I'm with Dave can't wait to see the maiden launching of the Gumpmobile!

The blades aren't stainless Steve, they are flat chrome moly.

Steve, I like the hex in your link. I wish my drag link had one. It's not easy to firm up lock nuts on various types of bars without them.

Jack that one is machined into it as it was hex bar but on a round tube i just drill out a nut and drill a hole in one flat and plug weld it in place.

I'm sorry Steve but I'm receiving flak about discussing your anti roll bar---

But---------you did use a right and a left handed heim joint????????????/

What welding rod do you use to weld stainless to 4130 and do you purge the inside of the tube??????????


I'm assuming that the tube is either .083 at .8129 lbs per feet or .095 at .9182 lbs per ft------------

Jerry its .95, I'm not welding stainless to the moly, the blades are moly too. I use A15 rod which I think is the same as your ER70 ? Yes the joints are RH & LH, wouldn't be adjustable in situ otherwise.

Steve----when I order tubing the prices come down as the number of feet go up so I'm always adding stainless for brake and fuel lines and lengths of tubing that have a od/wall thickness combo to result in a standard tap size id for threading---I think 1/2 .083 results in tap size for 3/8??????????????anyway, don't know what the availability and sizes available over there but there are 2 or 3 big suppliers right near here and they are always ready to talk to racers!!!!!!!!!!

I never tap directly in to tube Jerry, I was taught to always weld in threaded bungs, Unfortunately I don't use enough Moly to buy in bulk.

so if this worked---where's the ARB?

Gosh, Jerry, I can't find one. Of course I couldn't find one on this either.

With that, I'm done with this discussion.

Steve--I agree with the welded bungs in the end of tubes for the healthier links----I do the directly threaded tube fo things like throttle linkages(your carb pics reminded me), goKart steering links, clutch/brake--------probably nothing bigger than 1/2 od

Jack---------------PETA will be after you because of the dangerous things your doing to those birds habitat around the landing strip------------------
