assembling a hand

Figure 1: Hardworking or hardly working?

Last week, we made great progress with the assembly stage of making a hand. After inserting the strings two weeks ago, we began to attach the chords to the main tensioner pin. We situated the pin closer to the tips of the fingers to increase tension/tightness such that, at a relaxed state, the hand is straight. We then inserted the tensioner block and screws, as shown below in Figure 2.

From my understanding, this would pull the pin and strings back to further tighten the hand.

At first, Elda and I (Jag) made the strings too loose so we had to redo it again (take out the block, undo the fisherman's knot, etc etc).

Eventually, our loose hand was fixed and we caught up with Kimberley and Samantha!
Then, we inserted in the paddings, secured by the screws, as well as inserted in the Velcros.
So, that was what we did last week.
Today, we will be on a bit of research while Kimberley and Samantha build hands of their own. (next blog post)
