Angus MacKirk Grub Steak Sluice - Highbanker Conversion

[Nugget]

Can you remember what thickness the aluminum was? and do you think 0.5mm would do the trick?

I'm no expert but after doing some research on "bush power" this is my take on it:
Firstly I wouldn't use a car battery as they're designed for short sharp use to crank a motor. When used constantly to drain power from it will have a short life. A deep cycle battery is designed for this sort of thing.
If you had say a 1000gph 3 amp pump to run for 8hrs you would need a battery capable of around 48 amphours e.g.
Required amps (3) x hours (8) = 24 amp hours
Just about everything/everywhere I checked recommended not to discharge the battery by more than 50-60% (so 24 x 2 = 48ah) to increase battery life. This is just an example to add your own figures to.

I emailed angus mackirk regarding the exact question. Apparently the grub steak works between 500 to 700 gph.

Thanks for that mate, I may look at getting something a little bigger and regulating the flow via an in-line valve. I'm heading to BCF on the weekend so I'll checkout what they have.

Does anyone know how long a bilge pump would run on a small car battery?

nugget, BCF is ok but they really only stock the basics in boating gear, that is if it is a bilge pump you are going to use. i am assuming that you are going to Rutherford BCF. My suggestion would be to go a bit further and in Mayfield there is a bias boating gear shop in the vicinity of maccas and I am thinking could be across the road from woollies. there is also a Whitworths marine store in between shindigs and Hadleys cycles in Lambton these two shop specialise in boating gear so may have some different alternatives for you hope this is of help

Thanks bisho, but I've already picked up a Rule 1100GPH pump.

Thanks for the offer mate, I should be able to get some easily enough, but if not I'll be in touch.
