I hate the size of that picture but don't know how to downsize it.
But that shows a simple homemade hobble.
You need 4 rings and 2 snaps.; I used swade but material would work find. I space the rings about 7 inches apart, cut the material about 2 inches wide and loop it over through the rings until it is folded double and then just use the normal sewing machine to sow it up. I end up with the rings secured about 7 inches apart with material. I then use a very powerful elastic band folded twice on itself to join two rings. The snaps are easy to clip the hobbles together around the legs.
I have done 3 horses in the past year of so and none fought in any way other then the inital wrap of the lead around the leg and that was to only step out of it or shake it off. NOne went more then 3 times per leg at learning how to hold the leg up with the rope.
It is simple for 2 people to do. Any fight and let the horse escape the rope but repeat immediately and within a few tries he will accept.
Do this for 3 or 4 days or until the horse accepts right off the bat and then while stand quiet somewhere comfortable put on the fornt pair and stand and brush letting the horse get use to the feeling. If he has his homework done he will just stand. I then try the back.
Within the week I am brushing without cross ties.
As marecare said , ground tying, just dropping the lead, slapping on the hobbles is right there. A hobbled horse learns to stand quiet anywhere and once trained to just stand you will be suprised at how quickly they accept groung tying.
Any questions? Marecare obviously has a good handle on how to do it
