Found a better way to mark tube sheets for drilling
I was working on a big heat exchanger job for a plant in Gary, Indiana, and the tube sheet layout was giving me fits. The old way, using a center punch and a ruler, always felt slow and a little off. I tried something different this time. I took a piece of clear plastic, like a report cover, and drew the full hole pattern on it with a fine-tip marker. Then I just taped that template right over the sheet metal. It let me see the whole grid at once and punch through the plastic. It cut my layout time by at least half and the holes were way more even. Has anyone else tried a trick like this for pattern work?

My buddy in Toledo used a sheet of glass for the same thing last year.

Nice! That's a solid trick. It reminds me of how a lot of the best fixes are just about seeing the whole picture first. Like tracing a pattern before you cut fabric. You took a big, messy problem and made it simple and clear. That plastic sheet trick is just smart. It turns guesswork into a sure thing.
