As you may well know Winchboy bought a mystery engine which with some great help from the people on here has now been identified as a 1934 Royal Enfield, he has now found a partially complete bike to start his build, but as the wheels are missing and are shockingly expensive he needs to tighten his belt in other areas. So he now needs an ignition system, so how can we make one on the cheap? This chap sells some nice stuff http://minimagneto.co.uk/Products.php But if we made a total loss battery operated system using a bike coil we only need some sort of switching arrangement to fire the coil so we should be able to do it on the cheap? I am sure we have an electronics man on the forum? The challenge is on, can we build it for nowt or very cheap?
