85 GL1200A fork cap install

I had to replace the fork seals and replace the oil. I read the different ways others have compressed the spring to reinstall the fork cap from brute muscle to nice jigs. So at 180lbs, I tried the brute force with no luck.
I don't have all the tools to build a nice jig, but came up with a method using an old caulking gun. Once I figured out the best way to clamp it to the tube, it was easy from then on.
I just finished the left fork and should be able to do the right fork tomorrow.
I'll take some picture and list of materials and post once I'm done. Want to make sure it works more than 1 time before I put someone in a dangerous. It's bad enough messing with springs.

Thanks for all the previous suggestions and posts on how to replace the fork cap as well as other maintenance jobs.
