ineed9,
Head swelling (and not only the arrogant kind) can definitely cause problems. A little bit is good; it certainly helps the hanger to get a good hold. A lot is bad. It could lead to thrombosed veins and other unpleasant or dangerous effects I don’t even want to think about.
If your head is swelling too much for comfort, try loosening your wrap. Also, try completely removing the hanger and wrap between sets. I use only about 8” of 1.5” thick Theraband for wrap, so rewrapping for each set is really no problem. I always remove the wrap between sets.
I don’t think that a little bit of added pressure, absent any discomfort, is a great cause for concern. But you do want to be extra careful because you may occasionally go numb, in which case you won’t feel the pressure until damage is done. Vigilence is the key.
I have found the Turn-Key Clamp to be superior to the Cable Clamp in almost every way. Its only drawbacks are that it slightly slows attachment and loosening of the hanger, and that it tends to wear out after a couple of months of regular use. Best to keep a few on hand.
Unlike the Cable Clamps, the Turn-Key Clamps do not force any particular shape. In fact, they are quite flexible and will adapt their shape to the forces they encounter. Certainly, they apply more force to the sides, above the stick-on pads, than on the ventral or dorsal surfaces. In this manner, I really don’t think they perform any worse than the Cable Clamps. The only times I’ve had problems with numbness or reduced circulation has been when I’ve used a fulcrum, which I think directly cuts off the circulation and impinges the nerves, and when the hanger has become rotated so that the pads press on the top and bottom of the shaft rather than the sides.
What I like the best about the Turn-Key Clamps is that they are continuously variable. Sometimes, 1/10 of a turn can make all the difference between comfort and pain. That level of adjustability is simply not possible with Cable Clamps. What’s best is to be able to adjust tightness during the course of a set. I do this very often, sometimes 2 or 3 times per set. It’s great to be able to adjust tightness on the fly to maximize comfort.
I should also mention that the short length of the hanger actually reduces the amount of force needed to clamp down to any given tightness. You’re simply compressing less tissue than a larger hanger would. The result is that tightening the Turn-Key Clamp is much easier on the fingers than tightening the wingnut on my Bib Hanger ever was.
I’m up to about 15#, and this hanger is showing no signs of giving up. The only problem I’ve had is that one of the stick-on pads shifted a tad (less than 1/16”). I removed and reapplied it, and the problem hasn’t recurred.
Please understand that I am experimenting with this design right along with you, so please use caution. I have not explored all the possible risks. One of you may come upon some defect or hazard that I haven’t seen. So please be careful and keep your eyes open.
