Tim, think outside the box, chum. Tools doesn't have to automatically mean ones for woodworking. I know, scary idea, eh? :wink:
Some thoughts based on the thread and private suggestions:
1. Tool restrictive - well it's just that; not everyone who wanted to enter would necessarily have the required tools.
2. Material restrictive - not everyone has the means to get a 2x4 or whathaveyou. A cost limit would favour folks with easy access to materials too.
3. Space restictive - anything you like as long as it doesn't measure more than AxBxC. As long as we can think of some sensible dimensions, that has possibilities.
4. Joint restrictive - another possibilty, but the choice of joint is tricky if you want to make it open to as many members as possible.
It seemed to me you want to aim for as many options for entries as possible to include everyone - from general woodworkers to the specialists like the turners and scrollers. And it needs to be something that people find interesting. You can claim that furniture or whathaveyou is what it's all about, but the truth is the stuff that gets most drooling from us all is tool and workshop related.
One last thing; if the options within the competition are too wide ranging, it's going to be murder to judge - and remember, you lot are going to have to do some of that too... :wink:
