so i hoiked the valves out and wire brushed the 2 i was going to test it out on........this model landrover made a mistake....they put double valve springs on and as a result it wears the valves VERY badly as you can see by the last pic'

soooo.............the area is now brushed up and ready to be prepared...so out come the valve guide cleaning "quills"....they are put in a drill chuck (just the one...the right size)...bit of petrol and wizzed up an' down the guide to scour it clean..........so the cutter "quills" will fit perfect (last pic)

choose the right size cutter quill....snap it into the expanding chuck ...so it locks in position....grind off a cutting wheel to 45deg' slide it onto the quill....put electric spinner on top.....bit of spring pressure ...and pull trigger for 3-4 sec's..........................
