Took 90 minutes to figure out a tube sheet layout I could have done in 20

Had a heat exchanger bundle to retube last Tuesday and spent way too long trying to lay out the tube sheet pattern with a ruler and calipers. Kept second guessing my spacing and counting holes over and over. Finally just used a cardboard template with a center punch to mark all the holes at once and finished the whole layout in 20 minutes. Has anyone else found a quicker way to lay out complex tube patterns that saves them from overthinking it?

Isn't it funny how we overcomplicate stuff until we remember the simplest method works best? That cardboard trick sounds just like how I finally stopped organizing my garage by label maker and started just putting things where I grab them.

Haha totally! My buddy spent a whole weekend color-coding his tools and gave up after day one.

The label maker thing is a trap. I bought one thinking it would change my life and it just sits in a drawer now. My garage is basically organized chaos - screwdrivers go in the coffee can, wrenches in the old shoe box. Works fine.
