Quoted from BJM-Maxx:I just went through the same problem on an Eight Ball. What I did was to shine a light up through the stencils on a play field glass to align them to each other. I snipped notches into the corners of the stencils where the legs cover them. That way you at least have a reference when doing the second colour on the cabinet. Even then I found I had to roughly apply the second stencil check alignment and adjust things, at least I had a reference. I found the twistedpins stencils were good quality but not well thought out in terms of colour order and they had no overlaps, everything had to be perfectly aligned.
Thanks, it's super frustrating. Not to mention the color sequence seems to be in reverse of what others have done White -> Red -> Yellow instead of Yellow -> Red -> White. I just took a look at Jim's restoration thread from a year and a half ago and try and use that as my guide. I only wish Qbass had documented the stenciling process a bit better.
This was probably not the best project to get my feet wet with stenciling.
