How do you stop the side to side wobble while walking the yoke? I've only used it twice now but 700lbs wobbling from side to side sucks. Is it just experience in walking with the thing?
In my experience, Chaos, the wobbling of the yoke comes from hand position and sometimes stance. To better explain, when you are gripping the yoke apparatus like you would a squat bar when squatting, the yoke will tend to wobble a lot when walking with it ! So rather than gripping the yoke like I described above, try placing your hands and arms out to the sides in order to stabilize the yoke while walking with it. Helped me out a ton !! Was able to move a lot of weight that way.
So, to sum it up, try gripping the sides of the yoke, and not the top bar that rests of your neck and back. If you still notice the wobbling, try widening your stance a bit. Not too much though or you won't be able to move quick with it ( since speed is a HUGE factor in strongman ). Other than those two things I just told you, I really don't know what else would cause the wobbling. Hope I helped.
Btw, VERY nice equipment. Never seen homemade equip. look that good before. NICE job !!!
