Fasteners extending outside the FRAME PERIMETER

Every match they would leave blue and red skid marks all over the carpet. It was like someone roadkilled a Smurf. - Koko Ed [more]

Re: Fasteners extending outside the FRAME PERIMETER

Well this make sheet metal designs a bit more difficult... back to the old flat head bolts with PEM nut option.

For those which cannot change their fasteners to flat head bolts, here's the McMaster part number that I think will save a lot of teams this year: 8782K12

1" wide x 1/4" thick polypropylene strips at $0.53/foot. Polypropylene is among the lightest and cheapest commonly available plastics, but even still, installing this strip around the outside of your robot perimeter will add just over a pound.

For comparison, using a 1/4" x 1" strip of Lexan will add over 1.3 pounds.
