TwistedPins helped me do a custom stencil for my Star Trek: Mirror Universe. For that I'm eternally grateful.
I'm a picky bastard; so keep this in mind... There was a signifigant difference between my portion of the MU design and the stock bally design. Let me explain.
On my cabinet; I had my own stencils. I designed them so that the colors were "stacked" properly so that registration issues could be mitigated. IE the yellow planetoid was a sphere shape... and the red/orange bands were overlayed on the full stencil. That way there were no issues with registration between red and yellow bands.
The head of the Star trek on the other hand was a stock bally design from TP. This had registration issues because each color was an exact copy as seen from the overall artwork. It didn't appear that TP gave much thought as to how the stencils stack. Example; the planet is a yellow base with red patterns on top. The TP yellow stencil had the red patterns "covered" so you only paint the "seen" yellow with their stencil. The right way (In my opinon) to do the stencil set would have been to provide the yellow base as a whole circle so the red patterns would register without issue on the planet. IE no blue background peeking thru.
This is my $0.02... it's possible that TP decided they wanted people to have the ability to only re-paint single colors. If so they designed the stencil correctly.
I'd still buy from TP; but I'd expect to need to tweak the stencil's with an exacto knife for it to meet my expectations/standards/process.
