hey, I tried doing a search on here and was unable to come up with good information without having to read through 147 posts. But I did a google search and this was the first site I found but there were lots more
I just made one last night. Not sure if its exactly like the others but it worked. I just got a large screw hook thing to hang it from. Then I got a large spring and some rope. I screwed the hook into the eve of the house, then i attached the spring to it and tied the rope to the other end of the spring. I will get some pics up tomorrow. Deuce liked it. I got all the stuff for it at Home Depot and it didn't cost hardly anything. I also made a flirt pole the same day.
We are making one this year. My husband would be better at explaining, but I'll give it a shot (I might make mistakes though, please correct me if I seem to be wrong).
We are buying 3 very large poles, maybe 6''-8'' in diameter, I'm not sure how high. Dig two holes about 8 feet apart (we are putting the poles far away so that when the dog is swinging they won't hit a pole) maybe 2.5-3' deep, then fill with cement. Then put the 3rd piece along the top and make sure it is secure. We are going to use a pully to put the rope through so you have controll on how high the dog is. You can use a garage door spring and attatch a jute cloth or rope to the end. I am probably missing something, but I think that's about right. It will give you an idea anyway.
