I have searched around the tutorials and have found a few youtube videos regarding how to repair legs and found one photo diagram on how to repair the head that didn't look too practical. Most of the customizations I’ve looked at are for the 30th year anniversary edition figures.

Here’s my question/situation:
I purchase some used figures in a “lot” from Ebay. Many broken pieces. I will repair what I can but I was thinking about mix-n-match and making alterations to make a few new creations for fun.

Any general tips and guidelines on how to Open these guys up? And any tips on how to change certain features and body parts –not just changing colors?
Thanks for the help!
