It didn't take long to discover two problems, when I installed my new Tank with Cabinet and Hood. First up, when fully open, the woodstained Lid came in contact with our white lounge wall. I was always jamming in a box of Tissues to hold it up. Secondly, if the Lid came down under gravity, it made a bang that you were sure would crack the Tank!
Whilst poking around in a local Hardware Store (as always, for something else), I came across these 'Lid Stays'. They're designed for lids on Clothes and Toy Chests, and the like. They lock into the open position, and with a gentle pull, will provide a resistance, and lower the lid without slamming.
So I grabbed one of these 'Stays', at about Aus $35. Took it home, out of the pack, and stood in front of the Tank. I originally thought I'd have it concealed inside the Hood. But unfortunately, there's a glass tank in there - no room for the Arm to lower (plus I was slightly concerned about oil or grease contaminating the Tank). So I had to go for the outside option.
Now, the instructions have everything mapped out, Metric and Imperial measurements, alternate opening angles, drilling templates. But all for a flat lid! Not for a sloped Aquarium Hood. So I mapped out in pencil on the end of the hood, lots of guess-work, in the open and retracted positions.
Now that I had a drilling template, the next hurdle was the attachment to the Lid. You can see that my Hood has very little overlap from the Lid. When I sit the 'Stay' on the end of the Hood, the 'foot' that attachs under the Lid, actually swings up
past the Lid! Hopefully you can see this, my solution was to Route out a shallow, in which the base plate would mount. This brought the 'foot' back in under the Lid (barely).
So, drill the pilot holes, position the 'Stay', pop in the screws, and back onto the Tank for a test. Excellant! Just a bit of an adjustment to the resistance with a scewdriver, and 'Bob's your Uncle!'
Now I have a four foot lid. And by rights, a lid this heavy should have both a Left and Right 'Stay' (yes, they do come in L and R). And in hindsight, I probably should have positioned the 'Stay' to provide more 'oomph' in terms of leverage. My 'Stay' is at full resistance, and could be a tad more gentle, but I know if dropped, it won't do more than frighten a couple of fish.
My 'Stay' is Model NSD-20R/L manufactured by Sugatsune. It's a marvellous little piece of engineering. And well worth the price.
