Hi Dave,
You have now well and truly dropped yourself right in it ! We need to see a digi pic of you in your cruck blacksmith shop forging the drift pins !
Re books - when you see em - buy em !
Crucks are quite and enigma. Nobody really knows where the design idea came from. A few have postulated about the origins of crucks but the jury is still out. I have found that the best place to discover and read articles about the development of crucks is within the pages of the Journal of the Vernacular Architecture Group - but be warned this can be more than a little bitchy and the VAGers are not noted for taking prisoners !
Regards
Ken Hume
Ken, just to be clear, were you referring to me, Tim, when you replied, Dave?
