From your description, I would suggest the following steps:
1. take that tower to the scrap-metal yard and sell it for scrap price.
What you have described isn't worth re-working for any ham radio
purposes .. especially that 6 m yagi.
2. take the few $$ you get for scrap and use it [with pocket funds] to
purchase a tower designed for your purposes .. even a new TV tower would
work very well
3. anchor your tower in concrete, even if using anchor rods/tilt-over
feature.
4. enjoy!
