Lessons in LOA truss block alignment with UOA

Small degrees or mm in the shape or position of the LOA strut block can mean LARGE misalignment by the time the Strut reaches the UOA.

Requires:
  • Square blocks from the start.
  • Drill press to drill the required angel of hole. In my case no angel, just a straight hole from the top to the bottom inside the block.
  • Testing of the exact degrees of rotation of the block when positioned on the mirror box so as to point each strut to the centre of each side of the UOA.
  • Use of a shim (narrow chock) to point the strut inward or outward to align with the LOA bottom ring.
  • This will have to be repeated for the required number of struts (8).
  • Also note my final version of the split block using hinges.
