thanks
it's a slow process, make the mold, take to vacuformer, wait for him to get time to run a sample, get sample and say oh Sh#$ it doesn't fit right, make corrections and repeat process till it's right. I found that ABS has a tendency to shrink in BOTH directions instead of just 1 like HIP plastic...causing all kinds of problems with my molds about a 4% shrinkage. but when it's done right it's 2-3 times stronger and wear resistant and I'm rough on my parts!
