My threads are intact but I have a feeling the extractor I was trying is for TA cranks so only .3 of a mm too small or something at 23mm. Didn't know about bearing pullers, maybe I should look into them ..
You want this kind, you can get chinesium ones off of ebay or the house of bezos for about £30, get one with enough reach to do crown races while you're at it
