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.

      Will the strength of the product be affected by the different manufacturing technique?

      Glad to see the die casting yielded a desirable result for the 3/16 inch shackle. They both look good, and glad to see you are moving forward!
