About this book

You've built a few river tables, but you're tired of the guesswork: over-pouring epoxy, dealing with bubbles, and spending hours sanding out uneven surfaces. This book is your bench-side companion, focused entirely on the two things that make or break a river table: getting the pour volume right and flattening the final slab to a mirror finish. No fluff, no beginner lectures—just exact formulas, material-specific tables, and step-by-step procedures you can apply immediately.

Inside, you'll find a complete pour calculation system that works for any slab geometry, including irregular rivers, deep fills, and additives like pigments and metallics. You'll learn how to measure volume using simple tools, account for wood movement and absorption, and mix epoxy in batches that don't overheat or gel prematurely. The flattening workflow covers both router sleds and drum sanders, with recommended bit types, speeds, feed rates, and pass depths for every common epoxy type. You'll also get troubleshooting tables for common pour and flattening failures, so you can diagnose and fix problems on the spot.

Whether you're building a coffee table or a dining room centerpiece, this book gives you the confidence to pour without waste and flatten without fear. It's the reference you'll reach for on every single project.

Barbara Johnson

★★★★

I've built three river tables and always ended up with either a 1/4 inch of wasted epoxy or a wavy surface that took days to fix. This book's pour calculation formulas are spot-on—I used the grid method on a live-edge walnut slab and mixed exactly the right amount. The flattening workflow with the router sled was a game changer. I followed the recommended pass depths and speeds, and my table came out glass-flat in one afternoon. It's now the only book I keep on my bench.

★★★★★

The book has good information, but it's not for total beginners. I already knew the basics, so I skipped the intro and went straight to the calculations. The water displacement method was a bit tricky to set up, but the grid method worked well. I wish there were more photos of the flattening process—the text is dense, and I had to read the router sled section a few times. Still, it saved me from wasting a $200 pour, so it's worth the money.
