We've had some very high winds here in Northumberland due to the thunder storms that have been hitting us. So, the azimuth linear actuator attachment that swings the array horizontally has managed to work it's way loose and the array is swinging around rather alarmingly.

I've come up with a solution which is to replace the attachment bolt fixing which was just a nut and a locking washer with a nylon captcher nut and it seems to be a lot firmer. I think that the attachment brackets that come with the linear actuators probably need changing as well as they don't have a ball bearing attachement, just a simple pin and hole arrangement.
