Thanks for that Matt i'll look into it and see if it works.The drill is 18, and when the battery is first inserted it is a bit fierce, so less power might be better.It's a bit bonkers that i can do something with two bits of wire and those import people can do the same and flatten a car battery.If Alex proposed a more reasonable cost say 800 all in i might have a go and then it could be ascertained if it worked or not.You'd think these cox people would want to push a new market.Here's what i wrote before i saw your reply.
When i first put my system together it was always going wrong- airlocks ,pumps cycling- now it never does.The same with hot- loud bangs in the back of the van and clouds of steam as another hose blew up like a bycycle tyre and popped.Now never a peep of a problem.
Now , as you know i have just switched to two poles, two pumps, and two reels and all sorts of things keep happening. A scudo is a very small van to have all this stuff so it's a little cramped.
Day two of my change of working method produced my highest ever earnings. Even i was a little taken aback by what seemed like an ordinary day in the work sense. All the extra kit used i already had as spares, so to have to have buy a better reel is not the end of the world.
