Re: removing and adding chain links on motorized bicycle chain
A bench vise would make all the difference for a good surface but I don't have a shop or place to even have a vise, so it has to be the hard way. Last time I broke some chain down to size, I couldn't find my punch. I first used the chain breaker to get the pin started, then pushed an extra chain link into the hole and squeezed it on through with vise grips. If you have an extra link lying around of the same size chain, the pin will be the perfect size for the hole and you won't have to hunt for something else like a nail, which is rather soft.
