"cylinder head removal kit"

[JonE]

I've read a number of old forum thread and seen the hook things made out of old spark plugs. But the reference to a "puller" (that screws into the spark plug holes and then has a differential smaller thread which enable it to be tightened down against a plate pushing on the head studs) seems a no-brainer as it requires no other tools or hoist to 'hang' the engine from. And yet there is no futher reference to such, photos or anything.

Does the method work, and has anyone got a simple method of making them which doesn't require lathes or welding...? It can't be rocket science.
