IMO it's just/mostly a money makin' scheme (on a massive scale) :(

I understand that many folks are truly passionate about "savin' our planet"
...but, (again IMO) they have been "brain washed" :eek:
...& most educated folks know & understand that our earth has been a warmin' up...for...like...ever (true fact) :thumbsup:

My area (North west Ohio) used ta be covered by Glaciers (for a long, long time)
...& when they receeded, they even carved out the Great Lakes
...& filled 'em up with "fresh" water

But, now the Glaciers are long gone (from this area)
...& we (humans) had nuthin' ta do with it (another true fact) ;)

* Maybe it was them cavemen
...makin' their F'in fires, everywhere :devil2::innocent:

Everyone I know who is in the global warming will end the World as we know it camp really cares about this place we call earth. I like stuff that helps the planet, but there is a point of diminishing returns. :backtotopic:

I wasa talkin' about infos like this :thumbsup:

F.5.2 Bent Tubes or Multiple Tubes

F.5.2.1 The minimum radius of any bend, measured at the tube centerline, must be three or more times the tube outside diameter (3 x OD).

F.5.2.2 Bends must be smooth and continuous with no evidence of crimping or wall failure.

F.5.2.3 If a bent tube (or member consisting of multiple tubes that are not in a line) is used anywhere in the Primary Structure other than the Roll Hoops, an additional tube must be attached to support it.

a. The support tube attachment point must be at the position along the bent tube where it deviates farthest from a straight line connecting both ends
b. The support tube must terminate at a node of the chassis
c. The support tube for any bent tube (other than the Upper Side Impact Member or Shoulder Harness Mounting Bar) must be:
• The same diameter and thickness as the bent tube
• Angled no more than 30° from the plane of the bent tube

Another example:
This info, helps ta show folks "the proper way" to (for instance) mechanically (not weld) add a roll bar or cage to a chassis. ;)

F.5.12 Mechanically Attached Roll Hoop Bracing

F.5.12.1 When Roll Hoop Bracing is mechanically attached:
a. The threaded fasteners used to secure non permanent joints are Critical Fasteners, see T.8.2. Additional requirements apply in F.5.12.5 and F.5.12.7
b. No spherical rod ends are allowed.
c. The attachment holes in the lugs, the attached bracing and the sleeves and tubes must be a close fit with the pin or bolt.

F.5.12.2 Any non permanent joint at the end(s) must be a Double Lug Joint or a Sleeved Butt Joint
SAM_9597.JPG
F.5.12.3 For Double Lug Joints, each lug must:
a. Be minimum 4.5 mm (0.177 in) thickness steel
b. Measure 25 mm minimum perpendicular to the axis of the bracing
c. Be as short as practical along the axis of the bracing.

F.5.12.4 All Double Lug Joints, whether fitted parallel or perpendicular to the axis of the tube, must include a capping arrangement

F.5.12.5 In a Double Lug Joint the pin or bolt must be 10 mm Metric Grade 9.8 or 3/8 in SAE Grade 8 minimum diameter and grade. See F.5.12.1 above
SAM_9598.JPG
F.5.12.6 For Sleeved Butt Joints, the sleeve must:
a. Have a minimum length of 75 mm; 37.5 mm to each side of the joint
b. Be external to the base tubes, with a close fit around the base tubes.
c. Have a wall thickness equal to or greater than 2.0 mm

F.5.12.7 In a Sleeved Butt Joint, the bolts must be 6 mm Metric Grade 9.8 or 1/4 in SAE Grade 8 minimum diameter and grade. See F.5.12.1 above

F.5.13 Other Bracing Requirements

F.5.13.1 Where the braces are not welded to steel Frame Members, the braces must be securely attached to the Frame using 8 mm or 5/16” minimum diameter Critical Fasteners, see T.8.2 F.5.13.2 Mounting plates welded to Roll Hoop Bracing must be 2.0 mm (0.080 in) minimum thickness steel.

F.5.14 Other Side Tube Requirements If there is a Roll Hoop Brace or other frame tube alongside the driver, at the height of the neck of any of the team’s drivers, a metal tube or piece of sheet metal must be firmly attached to the Frame This is intended to prevent the drivers’ shoulders from passing under the Roll Hoop Brace or frame tube, and the driver’s neck contacting this brace or tube.

F.5.15 Component Protection When designated, components must be protected by one or both of:
a. Fully Triangulated structure with tubes meeting F.3.2.1.n
b. Structure Equivalent to the above, as determined per F.4.1.3

Have ya ever read thru a Formula SAE rule book?

It has lots of good info on "the proper way ta do things"

I don't follow it "religiously" :innocent:
...but, it's a great reference guide :cheers2:

If interested, you can down load it as a PDF file, from there website :thumbsup:

I use that as a rule of thumb, especially for head clearance for the roll cage. Also helps with keeping builds lighter but also being stronger. Less is more at times.

Good to know. Wasn’t thinkin about that one specificaly. Never heard of it in fact. But some kind of limited slip/locking diff would help handling a bunch. V1 likes liberal application of skinny pedal for best results.
come to think of it, it just likes liberal application of skinny pedal.

Back to our regularly scheduled programming.
Today on WTF we added the nose bars that will support the hip tube that wraps around the whole thing.

These tubes:

I put the frame on precision ground 1-2-3 blocks on my unprecision floor;

A cheap laser helps to keep things straight level and square:

I need 18 degrees to hit the right height for the hip tube.

Always wear the proper safety gear when welding. Or if you can not afford one of those fancy tanning bed things, TIG works equally well.
