Hi, I saw your timberkits on Dragons Den this evening and I wonder if you had considered marketing to schools, local education authorities or educational suppliers? Every year my school has the Year 5 and year 6 children build a project to give them an understanding of cams and levers, they make very dull, identical and rather pointless frames with a core spindle two cams and followers inside. How very much more captivating and engrossing it would be if they could choose and order what model they wanted to build, to enthuse and give a more satisfactory learning outcome.
I hope you find this suggestion helpful.
