Update - Frustration leads to innovation!

My wheel project is stationary at the moment for reasons I have explained previously, but things are gradually improving. Unfortunately I am still restricted by lack of space, however this has forced me to concentrate on the most basic requirements for solving this enduring puzzle.  I have built a simple test rig to try to solve the problem currently occupying my mind; how to make the weight fly upwards at the critical moment.

The pictures below give some idea of my working environment!  I'm sharing space with my son-in-law's two bikes, his cross-trainer, his complete tool chest for maintaining his bikes, a fridge-freezer, dishwasher etc etc.  Now they are formally in residence we are trying to make more room, but for now I must just bite the bullet.

I used to have the run of the whole workshop but hopefully things will return to normal at some point earl;y next year!  All my tools and equipment have been crammed into a small corner on the right in the above picture, to allow for the removal of the bikes from time to time.  I can barely turn around in the space left, but I will keep at it because I need the buzz I get from building new mechanisms and testing them to see how they work. 

I had been working with the whole wheel and all its five mechanisms but it is pointless to keep everything in a state of flux when all I need to know is how to get one mechanism to act the way I wish it to.  My test rig is just a simple two foot square of MDF which is painted white and has the critical angles marked out on it.  Certain angles, although apparently necessary to the succesful mechanism have to be omitted from the range of movement for reasons which are clear once you know how the whole thing is meant to work, and they are painted yellow and the critical one to abide by are in red, the rest is as I say, white.  I'm finding this detail  helpful in keeping the design within the limits of my self-imposed strictures which I believe apply to a successful mechanism.

At the moment I'm transferring some parts of the mechanism from the wheel to the test rig and then at every opportunity I return to it and continue my research. I'm certain that once I have achieved the reaction I am looking for I won't need to build the wheel to prove my point because it relates to something I have referred to from time to time and which is secreted in the string of letters I always include after my posts....but of course I will build it!

PS. I know the test rig isn't really an innovation, I just liked the ring of the title!
