OK. After a certain amount of grief (failed anchor point for the sheerlegs resulting in an aborted lift and a 1 week delay), the last section of the frame has been lifted. The timber that I laid out using chalklines as described above slotted into place near perfectly. One of those cut earlier had developed a little more twist since cutting and ultimately required the use of some not inconsiderable leverage to get it home.

Thanks again. I'll update the blog in a day or so.

Guys today i join this community and i read this topic and i want to ask a question a little about this topic which is that I want to lay a real timber floor for my house, not floating laminate, over concrete slab. Has anyone got this type of floor than share here some suggestions ?
