To remove them from the frame you could also use a metal pipe, but it needs to be soft, to not damage the cups so maybe copper.

Take it to a shop and have them use the correct tools for this job. The crown race extractor I use at work is an expensive piece of kit. Knocking the cups out just requires even pressure on all sides. When you see the tools, it’ll make sense. Paying someone a few bucks that knows what they are doing is the safest way.

Get a little hammer and a piece of softwood. Use it to tap around the race and go around it in circles. It’ll eventually come out. Otherwise go to a shop. But it’s doable at home.

If there’s a co-op bike shop/bike kitchen in your city take it there, use their tools and get help if you need it.

From the frame: with a headset cup remover ([like this](https://www.bike-components.de/en/ParkTool/RT-1-RT-2-Headset-Cup-Remover-p16045/)), from the fork with a different tool. Maybe [like this](https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Ffoto-thumbnails.mtb-news.de%2Fcache%2F980_auto_1_1_0%2F3c%2FaHR0cHM6Ly9mc3RhdGljMS5tdGItbmV3cy5kZS92My8yNC8yNDEyLzI0MTI0MjYtNnZ0N3FtaG53N2s0LWZvdG9fY2hyaXNfc3BhdGhfYmlyem1hbl9rb251c193ZXJremV1Z185Mzg1LW9yaWdpbmFsLmpwZw.jpg&f=1&nofb=1&ipt=f23a808fb832b0508cc6d40af11161a45857b8f17e5c1124990f851ad389f96c&ipo=images) or go around with a screwdriver and slowly tapping it from the bottom.
