I'm trying to make some Stop Motion animation but some of the parts on my Minifigures are very stiff, which reduces the control I have when making small adjustments during each frame.

Is there a safe way to loosen the joints that will still allow them to hold their position once set?

    Hi James, welcome to Bricks.SE. Can you describe your "patient's" condition or provide a picture? Ageing alone is usually not a problem. Sunlight or intensive play time is more challenging for the material over the years. – Aziraphale Jun 29 at 18:16
  • Can you clarify if you want to get them loose, prevent that, or fix? – Mołot Jun 30 at 14:55
  • I need them loose, because making stop motion is extremely difficult as some figures have some extremely still joins. – James Brown Jul 1 at 13:20
  • Please edit this information into your question :) – Mołot Jul 1 at 21:16

Both arms and legs are held in place through a fairly simple compression pin.

A small dab of washing up liquid applied to the joint should lubricate it quite well - avoid oils as they can cause discolouration of the plastic.

If that doesn't work for you, then you could try physically loosening the pins - gently pull the arms out of the sockets and the legs off the hips and replace them a couple of times - this is usually enough to compress the arms of the pin enough while still maintaining a grip on the part. Going further you can obviously compress the pins manually and fairly permanently - however this will likely make the joints too loose for your needs - I've certainly got some older minifigs with very wobbly hip joints that can no longer stand up on their own.

    See the comment by the OP. You answered the question hw didn't mean to ask. – Mołot Jul 1 at 21:15

    @Molot tbh, OP's question and comment are confusing and contradicting and frankly should be closed due to lack of clarification. This answer fits the asked (initial) question. – Alex Jul 2 at 13:16
  • @Mołot I've edited both the question and my answer based on James' comments. – Zhaph - Ben Duguid Jul 3 at 12:36
  • How would I go around compressing the pins? – James Brown Jul 3 at 18:27
  • A pair of needle nose pliers or even some sturdy tweezers. – Zhaph - Ben Duguid 11 hours ago
