Freewheel disassembly problem This is a cheapo Chinese freewheel, probably from a Walmart bicycle, etc. It's unusually heavy compared to my mountain bike's freewheel. I'm just trying to see if I can disassemble it. It's a learning experiment.  I've already figured out how remove the freewheel from the hub, and the gears (chain-rings) from the freewheel-hub assembly.  Now I'm trying to unscrew the central ring that allows access to the freewheel bearings and pawls. I can tell it's reverse threaded,  so I'm turning it the CW direction.  I have a pin tool for that spacing (which I normally use for bottom brackets), but the pins are too short to access the central ring's holes, b/c that central ring is recessed below the hub that the chain-rings slide over.  I've trying whacking a screwdriver tangentially in the CW direction, holding the tip against a hole. I get good purchase, not slipping, but the ring won't budge.  I've tried this with the freewheel installed on the wheel, and with it off the wheel &amp; secured to the bench, locked in place with the freewheel tool and a wrench. I've never had any problems removing that ring on any other freewheel, it's just a bearing cone after all,  so what's up? Any ideas?
This is the OP, George_San_Jose.  I finally got it turning. I'm not exactly sure what the  critical step was b/c I tried a combination of ideas.  The solution was some  combination of a couple days soaking in thread penetrant, working the job w/the freewheel on the wheel,  and using a steel center punch (rather than a screwdriver) to whack the hole tangentially with a hammer. I expect the latter was the most important, as some of the impact-value from the hammer was getting lost in the plastic handle of the screwdriver.
