Dome support ring trimmed and stacked

Today's task was to trim and stack the plywood arcs to form the dome support ring. To get the desired curvature I used a bit of timber as a tangent arm which was measure and drill for the inside radius of the dome, which in my case was 1215mm. This was nailed between the decking boards into the joist below, this allowed me to align the plywood arcs nicely.

The process after this was to align each plywood arcs joint using the tangent arm as a guide, trim if need to get a nice butt joint and repeat. This was done for each of the three layers. Total thickness of the Base ring is 36mm. By the way the bricks are there to hold everything together

Point of note is that the routing was so well executed the inside radius of the ring was near perfect.

Tomorrow's task is the to, level, glue and clamp.
