On the other hand, a Mini Cooper with a moon roof, hummmm.....

On a semi-serious note, a sheet of plywood, or a 2'X8' rip, with 2X12 sides and ends, lined with plastic, would make a shallow test tank, cheap. If you have it outside, you can just put it together, paint it, and no plastic. As long as you make good cuts and screw the pieces together, it will hold water for testing, and, eventually, self drain. That might eliminate the problem of trying to drain it.

or do what my wife just had me do, spend 30,000 on a inground pool. To justify the expense she called it my test tank Wow i got out cheap.

Wow! I lust in my heart after your wife, or, more accurately, your test tank! )

You could always use some protection.....bend the hooks over on a couple of sets of different size trebles, so you can test without risk.

Good idea. Paint the inside with white enamel paint, caulk/seal the joints, and you're set. No need to line it wth plastic, and installing a drain (pvc tube with cap) is simple.

I'd be tempted to stock it full of threadfin shad and one musky...just to watch.
When the shad are all gone, you've really got yourself a test tank.

To go back to the round test tank. If you used a high volume livewell/bilge pump to circulate the water and put a plexiglas window on one side you could analyze the action very easily. Move the lure closer to the center or adjust the pump output, or both for less speed. Maybe???

I really have given this a little thought... If the goal is to video the lure to examine how it performs, say a "wiggle to speed" ratio, I think a round tank with an island in the center with a variable speed pump is the way to go. Each lure of that design could be viewed and tuned to an exact profile and dynamics.
If you’re wanting more basic testing to test buoyancy and tune an individual lure, not a high volume production run, I think the portable test tank from plywood with a sheet of plastic or an even better sealing method would meet a craftsman’s need for lure testing.
I’m sure the great test tank de-bait (okay, I thought that spelling would be worth a smile) will continue, But, lets keep it fun, shall we?

Looks like the circular tank is comming out on top. There are two proposals for driving it:-
A) centre mounted paddle.
edge mounted pump.
Both will do the job, equally efficiently from a power point of view. But the centre mounted does have a few disadvantages, minor, but worth considering.
1) More work involved. The paddles have to be constructed.
2) a beam will be required to mount a bearing at the top of the paddle spindle.
3) in operation, the paddles will disturb the water close to the test area.
The advantage of the centre mounted drive is that a wider selection of motors will be available, which will probably make for a cost saving. Also, with a top mounted motor, no sealing will be required, as the bottom bearing can be wet.
Disadvantages of the side mounted bilge pump is cost (no research done, just assumption).
1) simple construction.
2) the whole drive mechanism is self contained inside the pump housing.
3) sealing is simple, comprising a rubber gasket or sealing compound, to stop leakage.
4) the pump, located at the opposite end of the tank, has minimum possible effect on the test area.
Incidently, if the tank was 6 feet diameter and 18 inches deep. The volume of water will be 264 gallons (UK) or 1.2 metre cube. My tap (pretty low pressure) at 23 secs per gal, would take 100 minutes to fill.
This thread has been excellent. We have now arrived at a practical, workable solution. Compact, low cost and reasonably storeable in a workshop. I hope someone does build it.

I agree, this has been an excelent thread and agree with 99.9 percent of group conclusions... Does this mean that we won't be going forward with Mini Cooper test tank prototype???
Posted 19 December 2007 - 12:58 PM
Oooops. Sorry 'bout that Vman.
Replace "Mini Cooper" with VW Bug or Ford Escourt, your pick. And I promise to never use "Mini Cooper" in vain again, unless it's as part of a really funny joke...

VM – you did not mention another important advantage. – A #### (valve) on the delivery side of the pump can infinitely regulate the flow or circulation speed, simple, no rheostats or gearboxes.
12V bilge pumps cost from $16 for 500GPH (8.3 gal/min) to $52 for 1600GPH (26 gal/min). I’m still not going to build one though! Pete

I think you could use a red neck test tank that being a plastic kiddy pool with a garden hose duct taped to one side would work great for ya... As for the picture of the test tank that bass4cache attached I think that if you dug up your back yard and cut a section out of your sewer line that would work too….before anyone gets upset about the red neck crack “I consider myself one at times”…as for the portable pool see my log in photo......

Just PM'd VodkaMan about this, I have been working on this idea- 'Every Mans Test Tank', but it's still in my head and am just too lazy to try it out (fear of failure), don't hold your breath as I have about half a dozen other experiments around the shed, in various stages of failure. I like the kiddie pool and hose idea, very inexpensive - but we have pretty severe water restrictions here (drought), buckets only "No hand held hoses"???. pete

Pete - Just remember, only 92 days until we have access to an indoor, heated "test tank" in Clinton. So, no worries mate...
PikeMastaRapp - Did you think I was just pullin' your chain about taking our "test tank" testing seriously??? NEVER!!! (figure that one out)
