I've built a few lids for outdoor tubs and thought I'd share the build process for my favourite design. Before you embark on a project like this you should know that it's a fiddly task that may take a few hours and will certainly require power tools.
For me a lid requires the following qualities:
- Strong and durable
- Easy to remove and replace
- Be completely weather proof
- Allow rainfall in
- Escape and predator proof
- Allow light through for plant growth
- Well ventilated
I experimented with a few designs before settling on a metal frame with mesh that fitted tightly on top of the tub. Using metal provided rigidity and strength, something that can be lacking in many plastic lids. The mesh I use is the smallest gauge I could buy at the garden centre with 6mm holes. This prevents even small newts such as alpine newts from escaping. Where I have used these lids for even smaller newts i.e juveniles, I've simply modified the mesh area by attaching a very fine plastic mesh underneath.
Here's what you'll need:
- Aluminium L profile strips cut with angled ends to the dimensions of your tub
- 4 x large corner brackets to fix the L profile together.
- Enough nuts and bolts to hold it all together (in this design that's 16)
- Some metal mesh
Below: - L profile aluminium cut to size, right angle brackets and nuts and bolts. Cutting the L profile is easiest with a power tool although I suppose you could tackle it with a metal hacksaw. I used a set square to draw the angles and an angle grinder to make the cut.
Here's how those components are going to fit together. It's a good idea to lay your pieces out like this so you can make sure it all fits before proceeding.
Here's the mesh I'm using.
When you're happy everything fits mark out the holes for the bolts and drill them using an appropriate sized drill bit.
Then, using the right angle brackets bolt together the frame pieces like so. Again, it's a good idea to put your frame together before inserting the mesh. That way you can make sure all your angles and joints work.
Now you can cut your mesh to size. It needs to fit well inside the frame but allow a little room for adjustments. The right angle brackets sandwich the mesh to the frame and keep it in place like so.
Once you've finished bolting all the brackets in place you should have something that looks like this.
The only thing left to do is grind off the excess bolt ends which are sticking out of the top of the lid.
Here's one indoors used as a breeding tub for N.kaiseri.
And a couple outdoors containing alpine and ribbed newts.
The 90 litre black tubs are made from food grade rubber and are frost and UV resistant. Combined with the lid they make ideal outdoor pond style setups. I drill drainage holes below the lid to prevent the water level reaching the top.
If you have any questions just ask!
