Rehab1 Posted December 13, 2018 Posted December 13, 2018 With @Marty Backe’s recent accident involving his shoulder and @Hunka Hunka Burning Love ‘s concern about re- injuring himself I felt it necessary myself not to take any further chances and decided to refine my Fox Titan Elbow Protectors. I had originally modified the elbow protectors months ago after my accident with 1” thick shock absorption foam. Original Modification Upon further discussion about my design with forum members there was concern that the foam’s surface would not allow enough slide in the event of another faceplant. I took this advice seriously. My enhanced design features a custom molded semi- rigid silicone outer shell that encapsulates the original thick molded foam. I also fabricated a carbon composite wear/skid bar. Enhance Design Containing a Molded Semi -Rigid Silicone Outer Shell (pre-trim stage) Post Trim Stage with Carbon Fiber Wear/Skid Bar Wear/Skid Bar Riveted To Semi- Rigid Silicone Cover Evaluation of Fit Prior to Final Assembly Cover and Wear Skid Bar Riveted to Fox Titans If called upon I now have faith that these modified elbow pads will disperse a significant percentage of forces that may impact my elbow and subsequent humeral region. They will also allow me to slide adequately. I understand that this modification is not easily duplicated but I have seen members come up with their own excellent mods based on other member’s input and designs. The shoulder and rotator cuff is an extremely vulnerable joint complex and is susceptible to incapacitating injuries. Any significant impact to the elbow can result in debilitating consequences to the shoulder’s intricate anatomy. If forum member’s have any additional ideas to protect the elbow and shoulder joints please feel free to share them. Thanks
Marty Backe Posted December 13, 2018 Posted December 13, 2018 Fantastic. All we can do is stare and drool Let's hope you never get to test them P.s. You sure those rivets won't potentially dig-and-grab instead of sliding
meepmeepmayer Posted December 13, 2018 Posted December 13, 2018 Most impressive workmanship and skills, once again. I know this kind of stuff is your job, but that doesn't diminish it in the slightest About the sliding, my guess is: the further it sticks out, the more it will impede the sliding. Small contact area = high friction. Hard shell surface or soft foam, probably doesn't matter so much. So I wonder if your mod helps because it cushions or harms because it rams the elbow into the shoulder. If I were going to build something to allow for sliding, the idea would be to have that thick piece of soft foam, but have it shear off with barely any resistance. Sacrificial foam. So it would be glued on very lightly, think double-sided sticky tape level of strength (or rather weakness). You crash, the foam hits and cushions, but stays in place on the asphalt and the "real" guard slides off it seamlessly, and then slides along the ground relatively unimpeded (because it's flat). I wish there was a way for you to crash (to test your approach) without crashing... hmm By the way, if you have the time and will, why don't you video your fabricating processes. I'm sure lot of people would be interested in the more advanced materials you use.

I am a motorcycle rider also, so bear with me here. Okay, here it is. I have vivid dreams of a textile or leather glove with form fitted palm sliders. Traditional motorcycle gloves have the sliders on the topside of the glove. EUC gloves would integrate them on the bottom -✋ side of hand. I think that they should be located on the heel and balls of the palm, along the bottom of the thumb, and on the finger tip bottoms. A bonus feature would be one that enabled the fingertips of the gloves to be flipped back to allow use of a mobile device or for grasping objects like a Grande soy 8shot latte from Compass Coffee, Kaldi's Coffee, or - I dare say, Starbucks 👍

You sure those rivets won't potentially dig-and-grab instead of sliding Thanks!! P.s....the rivets are comprised of top secret frictionless nano roller bearings providing unprecedented low (virtually null) static friction preventing the flattened stainless steel rivet heads from touching any substrate by means of repulsive dispersion forces. Because there is no contact there is no static friction and the nano bearing surface can rotate or translate in response to any driving forces. 3 hours ago, meepmeepmayer said: Most impressive workmanship and skills, once again.

So I wonder if your mod helps because it cushions or harms because it rams the elbow into the shoulder. I chose the semi rigid silicone material as a cover not just for the durability but also to maintain the shock absorbing characteristics of the 1” foam. I currently have no method to test my design but firmly believe my humeral head would not have shattered into multiple segments if I was wearing this gear. 3 hours ago, meepmeepmayer said: If I were going to build something to allow for sliding, the idea would be to have that thick piece of soft foam, but have it shear off with barely any resistance.

That’s what this thread was intended to do...nourish creativity.

I agree a crash test would be terrific but I have already auditioned for the sacrificial dummy. 3 hours ago, meepmeepmayer said: By the way, if you have the time and will, why don't you video your fabricating processes.

If you recall I use to record all of my mods but my work is so hectic these days I fabricate at a frantic pace between seeing patients. Too many 4 letters words.

It would be nice if a high tech protective gear manufacturer were to follow the forum and assist in designing protective equipment prototypes for members to test. I build braces for children so unfortunately my knowledge of state-of-the-art materials used in fabricating safey gear is somewhat limited. We do fabricate custom nose guards and kidney protectors and they seem to work.
