is 18 gage steel, used as a bracket on the chassis counted as an outward protrusion??

Can you provide any more information? A picture, or drawing of what you're talking about will help.

We are making a bracket out of sheet metal in order to mount a piston over the wheels. The bracket will go from the inner brace on the chassis to the outer brace. Are we allowed to mount the sheet metal brace on the outside of the chassis? It will be protruding from the chassis about 1/16th of an inch. Thanks in advance!

A picture or diagram would be helpful, but 'chassis' is not a relevant term really. FRAME PERIMETER is relevant. It sounds like the 1/16 inch protrusion would re-define your frame perimeter because it is not a fastener like a bolt head, etc (which are not considered in determining your frame perimeter.

I'm envisioning a piece that has a right angle and is fastened to your chassis on its outer face. This just becomes your frame perimeter and the chassis element will be within 1/16" and so would be allowed because it is less than 1/4" depth.

Again, the above is based on some conjecture about what you are actually trying to do, so it may not reflect reality.

As long as you stay inside the max frame perimeter 112 in you will be fine.

Be very careful saying that. It all depends on where the bumpers end up relative to this bracket, because if this bracket redefines the frame perimeter then it also changes their bumpers!

True, but its up to them to determine that. I was answering the question asked, and without more info or a picture I'm not going to bring in more rules to cloud the waters.

It's hard to visualize what you mean. I surmise that your steel piece would end up defining your frame perimeter, rather than being considered a "minor protrusion".

I've found a rule pertaining to a protrusion of that diminutive size. look at 4.1 R2 and if that doesn't feel acceptable you should ask the Q&A

R2 is what you have to comply with. As long as a small bracket & bolt did not exceed 1/4", I would consider it a minor protrusion. At some length a bracket would cease to be minor. Inside the bumper zone it could be considered part of the frame perimeter. Legal if the rule frame perimeter rules are met. Outside the bumper zone it would have to be a minor protrusion. Q&A generally punts these kinds of questions so ultimately it will be up to your robot inspector.
