It is helpful to have a good selection of tools and a good work bench with a vise . And remember that the retainer is left hand thread . If it's hard to start turning , you may get discouraged and question if you're turning it the right way .
The only reasonable way to do it without the proper tools is to remove the left handed lock ring, clamp cog into a stout vise and holding the rim firmly turn counter clockwise until it breaks free. Good chance the cog may pop out of the vise as well.
FIRST THING A SHOP NEEDS IS A PROPER VISE, THAT IS AND ONLY IS A WILTON VISE. A BIG ONE WITH THE ROUND BODY.

Best to just buy a skip tooth cog already mounted on the driver. Or, take off the LH thread lock ring and put the wheel and chain back on the bike. Stand on the brakes and it should pop loose. If it does, you saved time. If it doesn't, get out that big hammer. :mrgreen: Gary

Yes! Ex-freaking-zactly! :shock: :shock: :shock: I priced those Wiltons, the larger ones go $700, Sheesh. The Chinese version of the same size (notice I didn't slip up and say equivalent) is $159.
I have Wilton #1760 6" and a Wilton #835 3.5" vises. The 6" I bought new for stupid money (no regrets) and the 3.5" I purchased at a garage sale for $5. I have used and broken the huge Chinese vises, no comparison and 20-30-40 years later you will be glad you stepped up. These vises will go to my grand kids as good as the day they were made. The six inch which is the new one I have already had for 25 years.
Score on the driver. Good question on the rims, were they immediate post war or a little later? In general 1/2 pitch chains came on the upper level bikes, us poor kids got the 1 inch pitch stuff.
