What I found out when I put on different freewheels on my new set of wheels was that the appropriate freewheel removal tool for Regina freewheels, the Park Tool FR-4, didn’t work. It just didn’t want to go over the lock-out nuts as the inner diameter was just a tiny fraction of an inch too narrow. So, I had to ask for the help of cousin Gordon with all his tools and his machine shop, and he was able to drill the inner diameter just the tiniest amount wider. And I also found – on Ebay again – a Germany-manufactured removal tool with a minutely narrower rim that also fits
Here are the three freewheel removal tools I now have for Regina freewheels:
The tools are, from left to right: the one manufactured in Germany, the widened Park Tool FR-4, and the original Park Tool FR-4.
