When we were delivered Whaam! it had a bent mast that looked like this…

Then Ed and his grandad tryed to re-bend it but in the process ended up snapping it into 2 pieces

Yes… we did jump on it a bit!!!!!

Then after it was broken we had no choice but to put a patch around it..

As you can see. Underneath this patch, there is three stailess steel bars which are evenly spread around the inside of the mast and screwed right through. This is what provides the strength for the mast, with the patch alone, it would not stand up to the force of cherubing, and it would be dangerous to put hardly any rig tension on.
