So, quick update. I managed to get the pin clipped, drilled new holes and have a much larger pin in place. I had to file down some of the leg to reach the pin. This has resulted in a bit of a gap between the knee joint and the leg armour. I don’t think it looks too obvious.

The picture is a bit blurry, but it shows the length of the pin. It goes down the same depth as you can see protruding. This is substantially longer than the previous pin and there is no room for it to drop further into the leg, thereby shortening the length of rod going into the knee.

I will post more when I have the model ready to rock and roll. It needs some damaged paintwork repaired and a few additions/changes to the paintwork while I am at it.
