![]() Touch the end of the solder to the top of the joint.Unwrap some of the solder from its roll.When the copper at the joint starts to change color, it's starting to get hot enough to receive the solder.Move the flame around the joint to distribute the heat evenly.Keeping the torch as upright as you can, begin to apply the flame to the joint.You won't need a high flame for this soldering operation. Once you see the flame, you can adjust the intensity.Give the propane torch valve just a slight turn to get the flame going. Using a small brush makes this easier, but we just used a rag. Daub a thin coat of flux on both the exterior surface of the pipe end and the interior surface of the elbow.The scarring will create a more receptive surface. Rub the joint surfaces with some sandpaper.Solder will adhere only to clean copper, so first, clean the elbow and the tip of the pipe.Once you're done, you can disguise the rim with rocks, as we have done in the photo above (alternatively, you can wait until the end of the project to do this). Depending on the readings you get from the level, it is at this point that you'll have to remove the pond liner from the hole and adjust its sandy floor accordingly. ![]() Your goal is for the liner's rim to protrude approximately one inch above the soil surface (disguise it later with stones) so that soil doesn't keep dropping into the water. Just scoop out a little or pour in a bit more to alter the height of the liner, as needed. Why? Because having a sand base gives you some wiggle room, in terms of achieving a good fit. 1 inch of sand will also be applied on the ground under your liner.If, however, after you're done digging, you find that the sides came out uneven in places, either apply sand (to build out a depressed area) or remove a little more dirt (to shave off areas jutting out). Try to keep the sides of the hole straight. Make the depth of your hole approximately the depth of the pond liner.Now that you have a guide to go by, remove the liner and dig out the hole into which the liner will later be placed.Place the pond liner upside-down on the ground where you plan to dig and trace around it, so that your hole will be the right diameter. ![]()
