Shackle Production Update #1
We've placed the order for all the tooling to manufacture the shackles. Our experiments to investment cast the 3/16 inch shackle did not go well, as it is so small. Fortunately, we simultaneously did tests on die forging the small shackle and they did go well.
Below is a photo with a 1/4 inch investment cast shackle on on the left and two 3/16 die forged shackles on the right. The polish on the 3/16 inch shackles isn't perfect, as you can see, due to the fact these were just tests to see if the die forging was feasible.
