29.01.2021 Another block in the ring.

 *

Friday 29th Below freezing all day and overcast. I have moved another block. Using the plywood, arc templates is proving essential to maintain the correct positions. Plus one more block, after lunch, to make five. The sixth needs to be moved only 4" and is already half excavated. That will be half way. The continuing frosts are making it difficult to penetrate the top two inches of the self-compacting gravel. 

Most of the posts tried, at the five new positions exactly match a joist on the veranda floor. The sixth to the eighth lie outside the veranda. Now I am wondering if I can make the building in two vertical sections. A lower and an upper half. Separated at veranda floor level. It will need serious connection between the two lots of vertical posts. 

The pairs of posts could be overlapped and [coach] bolted though. With my usual trick of sandwiching toothed star washers between the posts fitted around the bolt shanks. Plus hefty roofing washers to avoid the bolts crushing the timbers. They don't build skyscrapers from single vertical beams from top to bottom. Shorter posts or panels would make life so much easier. Something to ponder before I order the metric 2x4s. Shorter lengths would be lighter to handle and faster to erect. With lower risk of bent or twisted examples.
