I'll probably buy a cheapo PortaPower wannabe & pancake jack from Princess Auto (its like your Harbour Freight). Also on the list is a bushing press kit.
I hate having my abilities limited by bad or absent equipment or tools. Don't need that excuse.

Thats a fact of life, one rarely has the all the tools to do everything and thats where ingenuity and resourceful minds get to work and solve the problem with whats at hand in the moment.
You did good and I dont expect to do this for another 1500 hrs (about 20 years at current rate) and by that time I will have forgotten this and a lot more.

Back to my original problem of removing bushings (before I got sidetracked with the frozen pins).
After a little trial & error I found an easy way to get the bushings out:
1) Take an old screwdriver & grind its end to a chisel with a radius on the back. Try to get it close to the radius of the bushing.
2) Drive it between the bushing & bore.
3) Collapse the old bushing.
The rounded back of the chisel leaves virtually no marks on the bore. If you use a regular screwdriver you get 2 nice parallel lines. oops.
By the way, does anyone know why the cylinder ends rust? Every cylinder on my machine is the same.

New bushings installed:
1) Start bushing. There is a short section of pin inside the bushing to keep its shape while installing (you can see the end of it in the photo)
2) MacGyver bushing insertion tool.
3) Bushing almost in. I used that short section of pin with a snap ring to push it in the last little bit.
4) Done.
