Getting My Hands Dirty

Now I feel my mechanism design is getting somewhere I want to get into the workshop and start working with materials that I could potential use in the final piece. This is something that even the most expensive hi-tech software can't do, the physical making of the piece, something you can hold and tweak as you wish

I learnt a lot about realising this concept as a piece when making this wooden model. You can see from the two photos above how the movement of the column up and down causes the cogs to move inwards and outwards, it is movement that want to use to trap someone in the seat as they sit and push down the column. Also see how the cogs are suspended at a set height and distance from the column and can spin with ease on a metal rod, these are very similar to a Croquet hoops as they are pushed into holes in the base
