Duck island progress

Yesterday I made some more progress on the duck island project. See my previous post for an introduction.

Having bought some 4 inch ABS DWV (Drain/Waste/Vent) pipes and 45° elbows from Home Depot, I dry-fitted them within the frame. I’ll need to trim a couple to make them fit, but they should help add some buoyancy to the island:

Here’s a closer view of the pipes, plus a bucket that I’ll optionally use if I need more buoyancy (as I probably will):

If needed, I’ll add two or four such buckets spaced around the island, sealing their lids closed with silicone. I should be able to add them after installation, once I see how well it floats. (The lid doesn’t match the bucket as Home Depot didn’t have the black ones I wanted, and only had orange lids, but they fit the green buckets; I’ll face the lids towards the center of the island, so they won’t be visible.)

Pepper was supervising me:

Next I used scraps of wood and clamps to measure the boards for the platforms:

There are two levels of platforms; one should (hopefully) be right about at the water level, the second lower than that, as ducks find it easier to swim up then put their feet down to step higher. The lower ones weren’t in my original design, but I think will be a good addition.

I lifted the island to lean it on the shop door, so I could attach the platform boards; this is our first look at the top of the island, too:

Here are the water-level platforms, made from 1×2 boards, attached with finish nails:

A closer look:

Back down on the floor (and upside-down again), adding the lower platforms:

I know they aren’t super tidy; I didn’t bother cutting the boards at angles, or trimming with a nice clean line, since the ends won’t be visible when underwater.

Here’s a closer look at the two platform levels, and the pipe:

That’s it for now. Next time, I will trim the pipes and stick them together (I forgot to pick up the proper adhesive for ABS pipes from Home Depot, so ordered some from Amazon).

I will attach the pipes with some metal hanger straps, and add the pond liner that will contain the island dirt. I’ll probably also add a third platform level above the pipes to help hold them in place, hide the edge of the liner, and make another step for the ducks to jump to before reaching the dirt.

Then it’ll be time for installation! We’ll see how far I get next time. Stay tuned!
