Almost done with setting up the 22mm mainsheet car system.
After learning that the Harken end blocks would be around $200 each after tax, I resolved to make my own.
I laminated then trimmed some 5mm thick  ones of scrap carbon fiber. The end blocks attached by soft solution.
One result of a gifted car was that the pins were too bent to remove for attaching new turning blocks. Nobody stocks the 5/32″ pins needed. They said Harken would need 5 weeks and much money to replace. I am using stainless bolts from Stoneway Hardware.  Ends not fastened to the track in this picture.
