Some single use thingies: A cam chain holder to stop the chain dropping into the sump all the time. Better than string or wire because the motor will turn over.
A TDC finder. Made of an old plug which I threaded M10 internally, screwe a bolt in place, drilled and tapped that and screwed in a long M6 bolt.
The degree wheel is held in place by three rare earth magnets, it has marking for TDC and other markings 5 degrees apart up to 40 degrees. The short piece of tube, fits in the central hole and is a tight fit around the socket for centering. Once centred, it's removed to give the socket a little wriggle room.
