Thanks for coming on board Ken with that interesting update on your windmill project in the Barbados.
I for one take a real interest in mill construction having been involved with all 3 waterpowered mills at Upper Canada Village over the years in one way or another.
One thing that amazes me is the fact that each one was constructed no doubt without a major input from the powers above but mostly from a millwright with many years of experience.
At the output during preparation of each ones construction site, a thorough knowledge of the finished mill with its equipment had to be well understood.
Take for instance the Mulley Saw mill, the placement of the water Barrel or as some refer to it as the Rose Wheel at the extreme lower level of the site had to be within at the very least a few inches of both side and vertical placement so that as the stories were added and the machinery put in place things had to be right "on",.
Ken--Your reference to the search for 68foot timbers for the windmill arms brings to my mind what a monstrous construction it trully is, just the mast and main pinion timber, not to speak of the massive bearings to hold and contain this timber, along with the breaking system, and thrust problems that one would encounter during the furies of one of their many hurricanes.
Your problem of putting together shorter timbers by using a 6 foot scarf to reach the 68 foot necessary length seems to be quite a challenge.
As a question that comes to my mind how did you arrive at 6 feet rather than 8 feet or possibly shorter for the scarf, did you use historical or modern methods to arrive at this final size?.
And maybe you could just touch on the scarfing method for everyone visiting thi site.
