"Poor design of the counterweight attachment system – the single long bolt threaded straight into a thin cast area of the PMA base is probably not up to the job, especially if additional equipment/weight is fitted to the top end. I will be re-designing this setup in the future."
Graeme, you were spot on regarding this. My threaded slot for the hole has lost its thread, I assume due to the extra wear and tear from additional counterweights, and no amount of thread tape will allow the bolt to screw in. I have completely screwed through this hole with a 10mm bit, and have utilised a long threaded bolt to create a new fixing for the counterweights. I also had to increase the central holes in the supplied SW weights to suit the slightly wider bolt, but it feels a lot more secure now.
