Good place for plastic spheres

[Army Scout]

Working on a project I will need a couple different size and colored spheres. Anyone got a good place to go?

I recall someone talking about dying clear plastic a while back. Does this work? What kind of dye? Let's say you vacformed a visor and wanted it dyed a yellow tint?

Tamiya make a line of clear spraypaints for just this sort of thing. The only problem I can see is the optical clarity. Though the sprays and tints I've used are transparant and allow for light transmission, they aren't perfectly clear. If you need to see out of them, I would recommend getting getting clear tinted plastic sheet and vac-forming that.

Yes, clarity (vision through the visor) is the main concern. I swear someone mentioned Rit Dye at some point...

I've heard you can use rit dye on some plastics, but I've never heard of it being used on clear plastic.

We use Plastistruct domes on our starships.
But they come with **** in the center that must be ground off then polished.

We also used thinned down transparent turnsignal orange(amber) to tint the inner spinning dome's inner surface.
You can see thru it, but it would be more suitable for your visor to find a full face motorcycle helmet windscreen, and vacform from that to have full optical clarity.
Best of luck,
Ron

Sorry,I should have said... teets, or bumps

Rit Dye works on a lot of different materials plastics, metal, cloth, stone, the stuff is great.

The company I do web work for uses Rit to color code the plastic wire connectors they supply with their motors. Just remember the longer you soak it the darker it will be.

I've also seen folks mix Rit Dye and Future for use as a clear spray paint.

Chris,
There is a place called "Sphere City" or "Dome City" or something (no kidding) out in Simi or thereabouts.
I'll send you the link or post it here when I find it.

Can't find them, mybe they went under.
Here's one:

3-1/2"dia. x up to 1-3/4" high $39.00 ea.

That is too expensive.
At Plastistruct they are 7-8 bucks.
But they do have the teets in the center to grind off and polish away.
My starships use 3" inner spinning domes under 3 1/2" outer domes, so for one starship the domes(raw domes) cost about 40 bucks.
Alot for sure.
Transparent orange domes are nowhere to be found....

I'm interested in larger hemispherical domes to use for space suit helmet visors... :confused

 

[RShanko]

The place Vaderman put up there has 5 foot domes!

Talk about a starship.
What kind of helmet Karl?

 

[phase pistol]

Conceptual space suit thing I was working on awhile back.

 

[dropshipbob]

Cooooool! Not to hijack the thread, but I'd love to see more of that!

 

[phase pistol]

This was a sort of combat spacesuit thing I did for Halloween a few years back.

I'm thinking of renovating and redesigning it a bit.
