I was intending to clear up a little and grab some pics tonight but in my haste to finish the cam (for the return lift) after work tonight I made a total balls up and forgot to add the 25mm shaft to the overall diameter. Obviously it turned out a little on the small side!

Managed to salvage the cam but now need to fit a new larger bearing for it to run against. Will be a better design in the long run.... I hope!
