Mike and Pikey arrived just before 11 and spent a half day putting the hip caps on the east end of the barn roof.  They brought along a buck of their own staging to work from, so I removed the Goose Creek wall jacks and then sent an email to Sean asking him where he wants them delivered.  Pikey also brought along 72″ lengths of threaded rod in both ¼″ and ⁵/₁₆″ diameters… he thinking that the strength of the larger diameter would be needed to hold the cupola down.  Did the calculations and eight pieces of ¼″ rod will withstand over 8,800 pounds in tension and 5,300 pounds in shear.  Sounds like enough to me!  So cut the ¼″ rod into 9″ pieces and then used Mr. Angle Grinder to remove the eight ¼″ x 7″ too-short hold-down bolts from the cupola.
