Homemade Super-Neo Woofer: THE CHEVELLE RESTORATION IS DONE, dampener recommendations??

Haha, sorry man, was mostly being a smartass. It is probably 430FR stainless steel http://cartech.ides.com/datasheet.aspx?i=103&e=63

I'm somewhat surprised companies use stainless instead of regular steel, since steel is around 99% iron and stainless isn't exactly known for it's magnetic properties. It must be expensive to get the stainless steel which can handle magnetic permeability very well..............

If you cant get steel/iron thick enough then get two plates and weld them together.

And to wrap it all up

Let me know if that hurts your brain

Thanks I've seen that site, but the material list does not specify what grade it is. it just says ductile. I think I might go with steel instead, because iron is gonna corrode without any protection.

[STEvil]

The grade is listed:

120-90-02

100-70-03

80-55-06

65-45-12

60-40-18

Isn't steel just iron that has carbon added during smelting?

[Dwn4BassAlan]

The grade is listed:

120-90-02

100-70-03

80-55-06

65-45-12

60-40-18

Lol-ski I meant the chart on my diagramming program, the site that build the piece, they don't have the grading listed is what I mean.

They just had the word "Iron | Ductile" But no #'s....................................................

They only have 416 stainless, would it be better to go with 1008/1018 steel or 416 stainless?

Before I even have to edit, scratch that^^^, it was $400 more for just the top plate in 416 stainless, ain't nobody got no time for that.

Lol I don't know if you're hacking my internet history, but you linked literally every site I've looked at already, but thanks still. hahaha

I was having trouble with getting the plate and the pole lined up, and I was going to have a piece milled like this:

But, as you can see in the order box in the picture, they could not make it. So I decided, I'll just buy more neo to fill the gap

[Dwn4BassAlan]

So here's what ended up working, and here is what I drew up on that stupid ass CAD program and ordered.

The Top Plate; those small circular-cuts are 0.100" inch deep and I had planned on them to sort of let the magnet "slide in" and lock in place.

Dimensions: 7.8" inches diameter x 0.8" inch thick

The Base Plate; Same circular cut dimensions, but I also had the center pole circle cut down 0.200"inches deep so that it will really be secure.

Dimensions: 7.8" inches diameter x 0.7" inch thick

And an aluminum jig to hold the magnets separate while I glue them down.

Dimensions: 7.8" inches diameter x 0.100" inch thick

[Dwn4BassAlan]

I'm starting to think this will compete with a DC Neo because they claim to have 2400lbs of magnetic pull force, but with my combined magnetic structure, I'm looking at around a theoretical yield of just greater than 4,100lbs of pull force. But because my steel plates are not a full 1" thick my overall will probably be around 3600-3800lbs......

So this could get interesting..............I might need more spiders..........................
