What geometry of the disc does this supposed "nose spacer" change? I've never given it much thought. Yes, obviously the nose....but in what way exactly? I've heard this term used, but never thought really how it affects the disc.

I've worked in a toolroom building injection molds. I *might* be able to shed some light on this.

I've always imagined a very thin flat circular disc that is the width of the outer rim that goes in between the two mold pieces. This would make the depth of the inside rim deeper and make a taller disc. But then does the top have to have a spacer too the same width to keep the flight plate the same? I guess it might have too as well.

Did anyone save the old PDGA "Ask Dave D" forum thread? He said several times there is no such thing as 'spacers' for molding discs.

So much dg lore and “common knowledge” is debunked by going through that thread. I think it’s still archived.

It makes the nose thicker/blunter. The Millennium Sentinel is supposedly a Cobra with this added, which turns a fairly straight disc into an overstable disc. The Orion LS is another example that is a Sidewinder with the thicker nose.

If it's not a nose spacer could it just be a different core piece used for the mold?

Could be not a spacer but the molds actually have 3 parts from Innova, top wing and nose part. This also could help explain why Innova compared to Discraft has had issues with the molds not being as consistent, Discraft has specified that some Discraft molds used for DGA have a spacer.

I had a fascinating conversation with a friend who makes molds for phone case companies(machine was 10 ft from us during poker game) and I have talked to him about making a mold for me, and I probably one day will do things when I have the money.

He was saying that depending on what type of machine/plastic/injection points you use it could be anywhere between 2-5 pieces to make a disc mold. So depending on the machinery a “spacer” if they do in fact exist may work on a mold from one company but the base mold for another might not allow it to work for another.
