I basically spend the money on the wasted resin to avoid having to have it CNC’d. This resin flowing underneath gives me a perfectly flat base. I run these tables through a big planer, and the table needs to be flat going through. Unfortunately I kind of need to waste this much. Lots of people have politely suggested a number of ideas to prevent wasting this much resin. Here are the equations you need to calculate the dimensions of the pond liner you need: liner length length + 2 (depth + overlap width) liner width width + 2 (depth + overlap width) You may also need to determine the area of your pond liner for price estimation purposes. If you are thinking 13 liters is a lot of epoxy to waste, you are absolutely correct! These are a little rough on the underside, if they were perfectly flat I would only calculate for 1/16.” So for that i need to use the same volume calculation, but. I am going to calculate for an 1/8” that will seep under all the slabs. As it turns out, it isn’t that tiny of an amount! Eventually I figured out I wasn’t considering the tiny bit that seeps under the slabs and around the slabs. And I couldn’t figure out what I was doing wrong. I used to stop at this point, but my calculations were always short. So I punched in 11x195x2.75 to that calculator and got 96.7 liters.Īs much as I wish I we were done now, we aren’t. So I rounded down from 11.77 to an even 11” to compensate for that. I had one small island piece I was adding to my table that was going to take up a little volume. just make sure you are putting in inches, and they are giving you liters. Click here for a good volume calculating website. Thanks to this internet thing, people have done the hard math for us. Now we just need to turn our inches into liters. Which in this case was 2.75.” You’ll want to use the thinnest slab you have if they are different thicknesses.

And you probably remember from high school (maybe grade school for most people) to find the volume you need lengthxwidthxheight. The total length of my river(s) with all the twists and turns was 195.” Which means we have our length and our width now. For me, I had to measure around the twists and turns of my very unusual river. Sometimes this is as simple as the length of your table. Now that you have your average width, you need to find your total length.
