So I thought I'd break g1 cannon and put my grimlock into combined mode but his waist despite an obvious ratchet was terrible, it clicks and spins freely even without limbs.

I took him apart and it seems the teeth do fit (unlike cw skylynx) they just can't support it at all, how would I go about improving the ratchet clicks?

I can't force them together closer like with my cw skylynx because they fit, and not sure if using the old polish method would be safe to try, any tips?
