gussets

[Richard 2]

I agree with the tubular gussets... I used 1" x .120 DOM tubing for my gussets. (at every tube junction in the entire cage)

Charles

Guys Kiwi Steve told us if we used tubing for gussets he wanted to see 1 5/8" or the same size as the cage tubing. Because he said the 1" tubing mite perice the larger tubing. I would highly recommend sending Kiwi Steve pic's of your cage.

  I guess Kiwi Steve has never seen a professionally built frame.
  But in that particular frame junction it might be best. Our Alston Chassis has several 1'' tube diagonals in places not required
by SCTA.

 I didn't argue with him. But my SfI drawings for funny cars and dragsters show using 1" tubing or flat plate for gussets. But as they say we don't have car wrecks we airplane crashes.

I sent pictures of my cage and chassis to Kiwi and Lee K and all OK was the word..

My chassis is 2x4x.120 and 3x2x.187  with  1.750 x .120 DOM cage using 1.00x.120 DOM tube gussets.

The piercing comment seems out of place...the tube gussets are tube notched and TIG welded in at the angle so the surface they cover and join would spread the load on impact and also strengthen shear ?

No argument here. That's just what Kiwi Steve told us.

Hard to tell if you're really this ignorant or just being facetious. 

There's certainly a reason why plate gussets are welded on the outside of the joint.  Same reason why you probably wouldn't want a small diameter gusset tube welded nearly perpendicular to the center of a main roll cage tube.  If the tube gusset isn't the same od as the main tubes it's bracing it should be offset to the outside plane of the junction.  If it's going to be center mounted then it should be the same od as the main tubes.

Nowhere in the 2010 rules does it say that anything but plate gussets are acceptable. As I read the rules if you want to use knee braces from tubing you must submit calculatons showing their strength compared to the plate gussets .

Roll cage gussets.

If you are going to do a corner gusset with same size tubing, per Kiwi Steve, this is how it should look.

That is sexy!

correct me if wrong, any "knee" brace/gusset" with form or shape will be stronger than a flat .125 plate unless o-too-thin. Tubing included.
The real question is, "what is the intention of the flat plate gusset?"

Roll cage gussets

I don`t see those passing tech. The "open area" at the tube intersection is required.

   Well I guess you and Kiwi Steve haven't seen a pro-built chassis, or know more about chassis building than Chris Alstons
Chassis works.
  No one is saying to mount a smaller diameter tube [ours is 11/4''] perpendicular but diagonal which is not close to perpendicular.

  Looks like that diagonal is smaller. No good gona pierce
