I watched a video last year of Dave Dunipace finally admitting that a bead is simply a wear layer to make your discs last longer. It has nothing to do with flight characteristics.

Interesting. I think the general consensus is that bead adds stability.

I think more often discs get more understable due to tree hits that push the wing down. Sure there are scrapes on the bottom of the discs that have been thrown a lot, but I find it hard to imagine that it is so much as to merit another layer to be "sanded down" due to contact with the ground. I admit, Dave ought to know what he is talking about. Video would be nice.

There is the potential for flashing everywhere where the mold pieces connect. I believe all single-shot mold companies use three piece molds. The bottom of the disc is one of those places where the molds connects.

That is the flashing

i can't make sense of any of the responses so far, with all the horizontal and vertical talk. but i don't really get how flashing and any sort of bead could be confused. they are in totally different spots on the disc.
I don't know what company you're throwing, but Discraft and Innova look like they use three pieces, making for two areas flashing occurs: between the top and the wing, and between the wing and the core.

Where'd you find that pic? Just curious. I've always looked for pictures of disc molds.

As some of you may recall.....I have a particular interest in the actual molds that discs are produced in.

Where does the nose spacer go?

Let's not forget that MVP/Axiom only appears to have one point of flashing. They hide their core's flashing under their overmolds. And does no one remember the earliest runs of Prodigy that you could shave with the flashing on the bottom it was so bad?

Yeah, this is what I've always thought of as flashing, and it's present on a decent number of discs. The part way over on the wing (where top and bottom molds meet) ALWAYS has a detectable edge but I've never had to razor or rub this off. The flashing on the bottom, however, is annoying and needs to come off fairly often.

I've seen it with most brands, though I mainly have Discraft and Innova. Innova seems to be a little worse with flashing in my experience.

It's usually the last place you'll find flashing. Maybe it's inherently a tighter fit, compared to the wing to flightplate. But turn over one of your discs (not MVP/Axiom) and you can see the line and most likely feel it with your finger nail.
