Potential alternative to high/low & iso tests?
I know I'm not the only one here who dislikes high-low tests & the conflicting/unreliable results they often provide. I just had an idea regarding a different way of tagging a gate to a wheel. Isolation testing is a good alternative, but it's always good to have extra techniques & the more tools we have at our disposal, the better.
I was looking at two graphs, one taken AWL & another taken AWR. Due to the width of the drive pins & flies, the indications on the graphs had moved. A gate showing at 57.5 on the AWL graph showed at 55 when graphing AWR.
It occurred to me that this may provide a means by which a gate can be tied to a specific wheel.
We usually measure the offset caused by dialling in the opposite direction at the beginning of a manipulation to allow us to perform rotational conversions.
It should be possible to use this information to determine what wheel a gate belongs to :
for example, we find that the pickup differences are 0, 1 & 2, for wheel 3, 2 & 1 respectively.
We run a graph and find a gate centred at L50. If we now run a graph over this area using opposite rotation, we find the gate centre is at R48.
The fact that the gate has moved by 2 increments would suggest that it belongs to wheel 1. If the gate moved by only one increment, it would be on wheel 2, and if the gate doesn't move at all, it is on wheel 3.
We know that a gate won't always show when we are dialling in the opposite direction, but for the instances when the gate does show up when dialling in both directions, this should provide an indication of which wheel it belongs to.
I haven't tested this yet, so far it is just a theory, but I thought I'd put the idea out there. I'd be interested to hear any thoughts regarding, or results from trying this technique.
