I have been building Tip Downs for over 15 years, it took some time but we have it down to a really nice setup with a frame that folds up and you can fit 9 of them in a 5 gal bucket.
Here are a few pics. If your interested in these you can PM or email me

To balance them you can lean the frame to fine tune the balance or I also carry a roll of solder with me and if needed you can wrap a little around the handle of the pole.
