Background for those not already in the know: I build my own pumps. I built a totally overkill pump for my new HMS Prince of Wales battleship. It has a monster motor, 40mmdia x 15mm high impeller, and a 1/2" discharge line (yes I mix metric and standard. If NASA can, so can I). In order to get POW on the water for testing at the last battle of the year around here, I kludged a legal restrictor from copper pipe parts and soldered a 1/8" I.D. tube in it. This was held in with a very tight zip-tie, which held up well in testing in my pool. I'm wondering if it gave up, or if someone's stray BB shot the tie and stressed it beyond its limits. Either way, as I slugged it out with Mike Mangus, all of a sudden, there was a LOT of water coming up from the back of the boat. And the pump got loud, and sounded like a swarm of angry bees. The video of this event is linked to below! http://www.facebook.com/video/video...8869157377 Unbeknownst to us on shore, this event caused a radical increase in the current draw, killing a set of batteries. So don't try this at home! Just enjoy my foibles, cause hey, it looked cool And it was funny to see the other team try to sink me with a 1/2" discharge line wide open
If I let the ship get real low in the water (full of water), and then turned it on, it was probably a good 20-30 feet. Looked really pretty with the sun behind it.
