Answered: Cutting pieces from plastic similar to existent VEX pieces

[Mondo_Longwell]

My question has to do with cutting polycarbonates.

<R7f> states

Non shattering plastic from the following list; polycarbonate, acetel monopolymer (Delrin), acetal copolymer (Acetron GP), POM (acetal), ABS, PEEK, PET, HDPE, LDPE, Nylon (all grades), Polypropylene, FEP; as cut from a single 12" x 24" sheet up to 0.070" thick.
i. Plastic can be mechanically altered by cutting, drilling or bending etc., but it cannot be chemically treated, melted or cast. Teams may heat the polycarbonate to aid in bending.

However <R7b> states

Any parts which are identical to legal VEX parts. For the purposes of this rule, products which are identical in all ways except for color are permissible. Note: It is up to inspectors to determine whether a component is “identical” to an official VEX component.

My question comes from a a possible mis-inference of <R7b>. Must all parts cut from polycarbonate sheets be different from VEX parts? Is it allowed to cut polycarbonate into shapes that resemble VEX parts.

In specific context, I want to cut polycarbonate into the shape of a cam. The VEX advanced motion kit includes a cam, however I would like to cut one of greater size that VEX does not sell.

Is this legal to do, as long as I keep it within the legal dimensions of 12" x 24" and a depth less than .07" thick?

Or is it illegal regardless?

This is a legal and typical use of polycarbonate. <R7f> is an additional allowance of materials beyond that of <R7b>. There is no restriction that non shattering plastics be limited in shape to that of existing VEX EDR parts.
