I was just finishing Hayley's hand and decided that I did not feel comfortable with the small size of the hex tensioner pins as I think they might have the tendency to strip over time. Since Hayley is located in the UK, I figured that I should make something that is a bit more resilient and not likely to need maintenance in the future.
I started with some aluminum hex rod in the size that matched the hex holes in the gauntlet I printed for Hayley. I ordered this from McMaster Carr. I chucked the rod in my lathe and center drilled the end. Then I used a drill bit to bore the hex to the required depth. I followed this by threading the hole with a 0-80 tap and then marked and drilled the end for the string hole. Once this was complete I cut the rod to the proper length and then repeated the steps four more times. The rods are strung/connected now and I have to admit that I feel a confidence in these that I have never had with the plastic hex tensioners when they are printed this small. I realize this isn't the most basic procedure for the novice who does not have access to such equipment, but I still feel it is worth mentioning as most Makerspaces have a lathe and it is within the abilities of most people to learn. Part of my thinking is due to working on developing a hand that is a bit more rugged for outdoor and sporting activities and I am looking at creating more of the components in aluminum for an active young boy named Evan.
